以下針對本發明之實施方式，參照圖式詳細地予以說明。另外，在以下所示之實施方式中，對同一或共通之部分賦予圖中同一之符號，而不再重複其說明。 (實施方式1) 首先，針對實施方式1之頭皮環境改善裝置之構成予以說明。參照圖1～圖3可知，頭皮環境改善裝置具備筒狀之殼體1、握把2、及頭皮接觸體3。 在筒狀之殼體1之一端及另一端形成有吸入口11及吹出口12。在殼體1之內部，構成有可自吸入口11朝向吹出口12形成空氣之流動之內部空間。 又，在殼體1之內部配置有帶電粒子產生部13與送風部14。進而，在殼體1之內部配置有加熱器15與控制部16。 帶電粒子產生部13係用於使帶電粒子產生者。具體而言，帶電粒子產生部13具備2對針狀之放電電極與包圍放電電極之周圍之2對圓環狀之介電電極(未圖示)。 在帶電粒子產生部13中，藉由對放電電極與介電電極之間施加電壓而產生電暈放電。利用該電暈放電而在放電電極之周圍產生正離子及負離子。正離子係H＋
(H2
O)m
(m為任意之自然數)，負離子係O2-
(H2
O)m(m為包含0之任意之整數)。 送風部14係用於自吹出口12朝向殼體1之外部送出帶電粒子者，可產生自吸入口11朝向吹出口12之空氣之流動。在本實施方式中，雖例示作為軸流風扇之送風部14，但不限定於此。 上述之各部如圖3所示般，自吸入口11朝向吹出口12依次配置有吸入口11、送風部14、帶電粒子產生部13、及吹出口12。 加熱器15係用於將加熱器15附近之空氣予以加溫者。加熱器15至少配置於送風部14與吹出口12之間，較佳的是配置於帶電粒子產生部13與送風部14之間。加熱器15之構成不受特別限定，例如可例舉的是在配置於殼體1內之支持板上捲繞有電熱線之構成。 控制部16係與帶電粒子產生部13、送風部14、加熱器15、及後述之操作部21電性連接。藉此，操作部21可遵從所接受之來自使用者之操作而控制帶電粒子產生部13、送風部14、及加熱器15之動作。 握把2係為了令使用者易於利用頭皮環境改善裝置而由利用者固持之部分。在本實施方式中，在握把2上設置有用於由使用者令頭皮環境改善裝置動作之操作部21。又，在握把2連接有未圖示之電源線。藉此，頭皮環境改善裝置可相對於外部電源電性連接。 頭皮接觸體3係配置於殼體1之外部。在本實施方式1中，頭皮接觸體3之中至少與使用者之頭皮接觸之接觸部(圖2中棒狀部31之前端部分)係位於自吹出口12朝殼體1之外部送出之帶電粒子之流路內。因此，頭皮接觸體3係配置於吹出口12與頭皮之間，換言之，不是配置於殼體1之外部中之吸入口11側，而是配置於吹出口12側。 在本實施方式中，頭皮接觸體3具有複數個棒狀部31。該棒狀部31之前端部分成為與使用者之頭皮接觸之接觸部。如此之頭皮接觸體3具有對頭皮給予舒適之刺激之第1功能，與藉由將頭皮上之毛髮撥開並使其自頭皮浮起，從而使頭皮露出於外部環境，使毛髮之下之頭皮與自吹出口12送出之帶電粒子容易接觸之第2功能。 頭皮接觸體3與殼體1可一體地形成，亦能夠以可分離之方式構成。在可分離之構成之情形下，例如如圖3所示般，較佳的是殼體1具備使頭皮接觸體3之裝卸成為可能之裝卸開關17。 裝卸開關17例如可在頭皮接觸體3安裝於殼體1之情形下成為被按下之狀態，在頭皮接觸體3未安裝於殼體1之情形下成為未被按下之狀態。另外，圖2顯示頭皮接觸體3安裝於殼體1之狀態，圖4顯示頭皮接觸體3未安裝於殼體1之狀態。 進而藉由將裝卸開關17與控制部16予以電性連接，可使頭皮接觸體3之安裝動作與各部之動作連動。例如，在裝卸開關17被按下之情形下(頭皮接觸體3安裝於殼體1之情形下)，可藉由控制部16來禁止加熱器15之驅動或將利用加熱器15進行之加溫之程度控制為低度。又，在裝卸開關17未被按下之情形下(頭皮接觸體3未安裝於殼體1之情形下)，可藉由控制部16來許可加熱器15之驅動等。 根據如上述之連動動作，例如，在頭皮接觸體3安裝於頭皮環境改善裝置之情形下，可防止送風至頭皮之空氣之溫度變得過高。如此之頭皮環境改善裝置可具有在未安裝頭皮接觸體3之狀態下之利用比較高溫之溫風的毛髮乾燥，與在安裝有頭皮接觸體3之狀態下之利用比較低溫之頭皮護理此兩功能。 實施頭皮護理時之吹出口12與頭皮之距離較使毛髮乾燥時之吹出口12與頭皮之距離為短之可能性高。在該距離為短之狀態下，若自吹出口12送出之空氣之溫度過高，則有引起灼傷等之頭皮之損傷之虞，但根據上述構成，可防止如此之損傷。 實施方式1之頭皮環境改善裝置如以下般動作。首先，使自握把2延伸之未圖示之電源線與外部電源連接。另外，在頭皮接觸體3與殼體1為可裝卸之構成之情形下，預先使頭皮接觸體3安裝於殼體1。 其次，在頭皮接觸體3之棒狀部31與使用者之頭皮接觸之狀態下，操作操作部21。操作部21所受理之操作係傳遞至控制部16。控制部16遵從操作部21所受理之操作而使帶電粒子產生部13與送風部14驅動。 藉由送風部14驅動，在殼體1內產生自吸入口11朝向吹出口12之空氣之流動。又，藉由帶電粒子產生部13驅動，在殼體1內產生帶電粒子。所產生之帶電粒子乘著由送風部14產生之空氣之流動，自吹出口12朝外部送出。朝外部送出之帶電粒子逐漸擴散開。 此處，與頭皮接觸之棒狀部31之前端部分係位於帶電粒子之流路內。因此，朝殼體1之外部送出之帶電粒子之多數可前往棒狀部31之前端部分附近。進而，頭皮接觸體3如上述般，具有藉由將頭皮上之毛髮撥開並使其自頭皮浮起，而使毛髮之下之頭皮與自吹出口12送出之帶電粒子容易接觸之第2功能。因此，送出至棒狀部31之前端部分附近之帶電粒子可有效地到達在前端部分附近露出之頭皮。 如以上詳細敘述般，根據本實施方式1之頭皮環境改善裝置，利用棒狀部31之前端部分之第1功能，可對頭皮給予舒適之刺激。另外，利用該前端部分之第2功能，可使前端部分附近之頭皮露出於外部，藉此，可有效地使帶電粒子到達至露出於外部之頭皮。在如此之被給予舒適之刺激，且多數之帶電粒子所到達之頭皮上，其頭皮環境被改善。 作為頭皮環境之改善之具體例，可例舉有：(1)適宜地維持頭皮之水分量；(2)適宜地維持頭皮之油分量；(3)使用者感受之頭皮之狀態為舒適；(4)抑制馬拉色菌之繁殖；及(5)促進毛髮之育毛・發毛等。若該等之中至少1個被改善，則可認為改善了頭皮環境。 例如關於上述(1)，在表皮之頭皮之水分量過低之情形下，頭皮之障壁功能(抑制外界刺激導致之頭皮損傷之頭皮自身之功能)會降低。此係頭皮環境處於不佳之狀態。通常而言，雖認為若皮膚中之神經醯胺及玻尿酸等不足，則肌膚之保濕力會降低而引起皺紋及鬆弛，但皮膚之障壁功能降低亦為其一個原因。因此，可謂上述(1)為頭皮環境之改善之一種。特別是，在多數帶電粒子到達至頭皮之情形下，可考量起因於頭皮之表面被帶電粒子覆蓋，而抑制自頭皮之水分之蒸散。 又，關於上述(2)，在表皮之頭皮之油分量過低之情形下，與水分量過低之情形相同地，頭皮環境處於不佳之狀態。此係由於皮脂係頭皮用於發揮障壁功能之因子，若其不足，則頭皮之障壁功能會降低。因此，可謂上述(2)為頭皮環境之改善之一種。特別是，在多數帶電粒子到達頭皮之情形下，可考量起因於頭皮之表面被帶電粒子覆蓋，而抑制自頭皮之油分之過量之損失。再者，頭皮之油分量在其量過高之情形下亦然，也是頭皮環境不佳之狀態。此係由於會成為頭皮之黏膩、氣味產生之原因。 又，關於上述(3)，使用者感受之頭皮之狀態為舒適此事雖為相對的，但考量其為重要之要素。例如，感受到頭皮柔軟，或感受到頭皮溫暖等，可謂為頭皮環境之改善之一種。作為其他之頭皮環境之改善，可例舉例如感受到如頭髮髮量增加，以及感受到下述各者之減少，即：掉髮之介意程度、頭皮屑之介意程度、頭皮搔癢之介意程度、白髮之介意程度(感受到白髮顯眼之程度)、頭皮之氣味之介意程度、頭皮之分縫之介意程度(感受到分縫顯眼之程度)、及感受到頭為沉重之程度。 又，關於上述(4)，馬拉色菌雖為皮膚常在菌，但若其過量地繁殖，則會造成頭皮屑之產生及頭皮之搔癢。此係頭皮環境處於不佳之狀態。因此，可謂上述(4)為頭皮環境之改善之一種。 又，關於上述(5)，若毛髮之育毛・發毛之程度降低，則會引起頭髮稀疏。頭髮稀疏一般而言係不被期望之傾向，又，即便考量毛髮具有保護頭皮之功能之點，頭髮稀疏對於頭皮環境亦係不佳之狀態。因此，可謂上述(5)為頭皮環境之改善之一種。 根據本實施方式之頭皮環境改善裝置，如上述之頭皮環境之改善成為可能。其理由可推察如下。 例如，在僅具有帶電粒子產生部之吹風機之情形下，雖然包含帶電粒子之風係自吹風機朝向毛髮送出，但朝向頭皮送出事屬困難。其原因係由於通常頭皮由毛髮覆蓋，若朝向如此之頭皮單純地僅送出包含帶電粒子之風，則帶電粒子之多數在毛髮表面被消耗，結果而言難以使充分之量之帶電粒子到達至頭皮。另外，即便假設在吹風機之吹出口側附上梳子，梳子亦只不過具有用於梳理毛髮之構成，因此，難以使毛髮自頭皮充分地浮起，而使頭皮露出於外部環境。 相對於此，本實施方式之頭皮環境改善裝置具備頭皮接觸體3，其如上述般具有對頭皮給予舒適之刺激之第1功能，與藉由將頭皮上之毛髮撥開並使其自頭皮浮起，從而使毛髮之下之頭皮與自吹出口12送出之帶電粒子容易接觸之第2功能。因此，在對由毛髮覆蓋之頭皮使用頭皮環境改善裝置之情形下，可一面適宜地刺激頭皮，且一面使被給予該刺激之頭皮露出於外部。因此，對頭皮可同時地實施舒適之刺激之提供與充分之量之帶電粒子之導入。 可考量藉由充分之量之帶電粒子到達被適宜地刺激之頭皮，頭皮可維持適宜之水分量，及維持適宜之油分量等。又，伴隨於此，使用者可感受之頭皮之狀態為舒適。 又，藉由充分之量之帶電粒子到達被適宜地刺激之頭皮，期待可抑制馬拉色菌之繁殖。進而，藉由充分之量之帶電粒子到達被適宜地刺激之頭皮，亦可期待引起毛髮之育毛・發毛之促進。 在以上詳細敘述之本實施方式1之頭皮環境改善裝置中，較佳者係頭皮接觸體3之棒狀部31之前端部分(與頭皮接觸之一部分)與吹出口12之距離為15 cm以下。藉此，可使帶電粒子以更高濃度到達頭皮。然而，在此情形下，有必要注意到達頭皮之送風之溫度。具體而言，為了使到達頭皮之送風之溫度為55℃以下，較佳的是利用控制部16予以控制。 另外，上述距離為吹出口12與棒狀部31之前端部分之直線距離，且為最短之直線距離。該距離在構成上為10 cm以上。 又，在本實施方式1之頭皮環境改善裝置中，自帶電粒子產生部13送出之離子濃度較佳的是正離子及負離子總共為330萬個/cm3
以上。在330萬個/cm3
以上之情形下，可進一步提高上述之頭皮環境之改善效果。 另外，上述離子濃度在自吹出口12送出氣流之方向上，係於遠離15 cm之位置而計測之值。離子之計測可利用離子計數器而進行。 又，在本實施方式1之頭皮接觸體3中，就適宜地具有第2功能之觀點而言，較佳者係棒狀部31至少為2條以上。此係由於在棒狀部31為1條之情形下，有無法充分地進行將毛髮自頭皮上梳之行為之可能性。 又，自適宜地具有第1功能之觀點而言，較佳者係棒狀部31在長度方向上彎曲為碗狀。此係由於藉由棒狀部31彎曲為碗狀，與直線之構造相比，可放掉過剩之力，對頭皮給予更舒適之刺激。 又，棒狀部31藉由在長度方向上彎曲為碗狀，亦可適宜地具有第2功能。此係由於藉由棒狀部31具有呈碗狀***之部分，而可在該部分更適宜地將頭髮自頭皮舉起。 又，在本實施方式1之頭皮環境改善裝置中，在頭皮接觸體3之中，較佳者係至少棒狀部31之前端部分位於帶電粒子之流路內，而配置於該流路之外周附近。 此處，針對帶電粒子之流路及該流路之外周附近，使用圖5予以說明。圖5係用於說明吹出口之外徑之示意性立體圖。 首先，將自外部目視吹出口12時之吹出口12之外徑(圖5中以虛線表示之區域)視為排氣面(圖5中以虛線包圍之區域)。在圖5中，排氣面係欠缺了一部分之圓形。 將使該排氣面自吹出口12朝殼體1之外部側平行地連續移動而成之欠缺了一部分之圓筒狀之區域視為帶電粒子之流路。另外，自不待言在實際上，帶電粒子係一面朝四方擴散一面朝外部排出。 並且，所謂流路之中心附近，係意味著自流路所延伸之方向(自吹出口12朝殼體1之外部側延伸之方向)目視流路之情形下之中心附近，所謂流路之外周附近，係意味著自流路所延伸之方向目視流路之情形下之外周附近。 棒狀部31之前端部分配置於較帶電粒子之流路之中心附近更靠外周附近為較佳之理由，係如以下所述般。 帶電粒子一面自吹出口12朝向外部擴散一面被送出。因此，流路內之外周附近之帶電粒子之濃度有較流路內之中心附近之帶電粒子之濃度低之傾向。 以上述為前提，假定棒狀部31之前端部分配置於帶電粒子之流路內之中心附近的情形。在此情形下，在使頭皮接觸體3與頭皮接觸之狀態下，若使頭皮接觸體3移動(例如10 cm左右)，則露出於外部之頭皮成為在前端部分當前接觸之位置與自該位置偏離10 cm之位置之間的頭皮。此時，高濃度之帶電粒子所存在之中心附近之位置與露出於外部之頭皮之位置間產生偏離。其原因係由於，前端部分當前接觸之位置係流路之中心附近。 另一方面，假定棒狀部31之前端部分配置於帶電粒子之流路之外周附近的情形。在此情形下，在高濃度之帶電粒子所存在之流路之中心附近之位置與露出於外部之頭皮之位置間，與上述之情形相比偏離變小。其原因係由於，前端部分當前接觸之位置係流路之外周附近，位於其附近之露出於外部之頭皮之位置可成為流路之中心附近。 因此，藉由棒狀部31之前端部分配置於較帶電粒子之流路之中心附近更靠外周附近，可對露出於外部之頭皮更有效地導入帶電粒子。 (實施方式2) 本實施方式2在頭皮環境改善裝置進一步具備罩體此點上，與實施方式1不同。在本實施方式中，針對與實施方式1之不同點予以說明，有不再進行重複之說明之情形。 圖6係顯示實施方式2之頭皮環境改善裝置之立體圖。如圖6所示，頭皮環境改善裝置進一步具備包圍頭皮接觸體3之罩體4。罩體4具有形成流路之功能，該流路用於將自吹出口12送出之帶電粒子引導至與頭皮接觸體3接觸之頭皮。 具體而言，罩體4係連接於吹出口12之吹出口側端部41與對向於其之外部側端部42開口之大致筒狀。特別是，自吹出口側端部41朝向外部側端部42由罩體4包圍之區域具有大幅度擴展之形狀。具有如此之構成之罩體4可在不阻礙頭皮接觸體3之功能之下，構成將自吹出口12朝向外部送出之包含帶電粒子的空氣有效地引導至頭皮接觸體3之棒狀部31之前端的風路。 罩體4可如圖6所示般與頭皮接觸體3一體地形成，亦可作為與頭皮接觸體3不同之構件而個別地形成。 假如在沒有罩體4之情形下，包含帶電粒子之空氣在自吹出口12到達頭皮為止之間可自由地擴散。因此，到達頭皮之帶電粒子之濃度(個/cm3
)較自吹出口12剛送出至外部之帶電粒子之濃度(個/cm3
)變小。 相對於此，根據具備罩體4之頭皮環境改善裝置，自吹出口12送出之包含帶電粒子之空氣係被引導至罩體4構成之風路內，而到達至該風路之端部附近之頭皮。在此情形下，與包含帶電粒子之空氣自吹出口12到達頭皮為止之期間自由地擴散之情形相比，可使更高濃度之帶電粒子到達至頭皮。 (實施方式3) 本實施方式3係使用實施方式1或實施方式2之頭皮環境改善裝置的頭皮環境改善方法。該頭皮環境改善方法係在使頭皮接觸體3與頭皮接觸之狀態下，朝頭皮送出帶電粒子之方法。 圖7係顯示將實施方式3之頭皮環境改善方法予以實施之態樣之示意圖。圖8係顯示於實施方式3之頭皮環境改善方法中之頭皮附近之狀態之示意圖。 在本實施方式中，如圖7所示使用頭皮環境改善裝置。藉此，如圖8所示，可使頭皮接觸體3與頭皮M接觸。 如上述般，頭皮接觸體3具有對頭皮給予舒適之刺激之第1功能，與藉由將頭皮上之毛髮撥開並使其自頭皮浮起，從而使毛髮之下之頭皮與自吹出口12送出之帶電粒子容易接觸之第2功能。藉此，可一面適宜地刺激頭皮，一面有效地使帶電粒子到達至頭皮，因此上述之頭皮環境之改善成為可能。 上述方法係例如在使頭皮環境改善裝置之頭皮接觸體3之棒狀部31之前端部分與頭皮接觸之狀態下，在頭皮上使該前端部分移動。此時之移動較佳的是將在頭皮上滑動前進之前端部分引起之刺激設定為使用者感覺舒適之程度的速度及強度。 利用上述移動，在前端部分移動之頭皮上所生長的毛髮成為自頭皮浮起之狀態。亦即，與不使前端部分移動之情形相比，更大區域之頭皮上之毛髮成為自頭皮浮起之狀態。藉此，可擴展在頭皮之中使帶電粒子有效地到達之區域。又，利用該移動，可對頭皮給予更舒適之刺激。 [實施例] 以下顯示實施例及比較例而更具體地說明本發明，但本發明並不受該等任何限定。 (研究1) 將40歲以上65歲以下之6名之女性作為被實驗者，隨機地每3人分配為試驗區1及試驗區2，實施雙盲交叉試驗。在試驗之實施中使用機器A及機器B。機器A係實施例之機器，其相當於實施方式1之頭皮環境改善裝置。機器B係比較例用之對照機器，其相當於自實施方式1之頭皮環境改善裝置除去帶電粒子產生部13後之裝置。 〔試驗〕 由不同於被實驗者之第3者(檢查工作人員)來實施對試驗區1之被實驗者之右側頭皮之第1處理。具體而言，對試驗區1之被實驗者之右側頭皮實施60次以下動作，即實施在使機器A具備之棒狀部之前端部分與頭皮接觸之狀態下，在使該前端部分自頭部前方朝向頭部後方移動3秒鐘後，將前端部分自頭皮離開2秒鐘此動作。藉此，對試驗區1之被實驗者之右側整體之頭皮，實施5分鐘由棒狀部引起之刺激與包含帶電粒子之溫風之送風。 在結束上述動作之後，實施60分鐘使該被實驗者處於安靜之狀態之時間間隔。在結束時間間隔後，實施對該被實驗者之左側頭皮之第2處理。對左側頭皮之第2處理除替代機器A而使用機器B以外，係設定為與對右側頭皮之第1處理相同。藉此，對試驗區1之被實驗者之左側整體之頭皮，實施5分鐘由棒狀部引起之刺激與溫風(不包含帶電粒子)之送風。 表1顯示機器A及機器B之使用時之各設定條件。另外，表1之溫度係由配置於自吹出口離開15 cm之位置之溫度計測定之溫度。 [表1]
根據以上可知，在試驗區1之被實驗者中，對右側頭皮之整體實施使用機器A之第1處理，對左側頭皮之整體實施使用機器B之第2處理。 另一方面，對試驗區2之各被實驗者，除在對右側頭皮之第1處理中使用機器B，在對左側頭皮之第2處理中使用機器A以外，係實施與上述之試驗相同之試驗。亦即，試驗區1之被實驗者之右側頭皮及試驗區2之被實驗者之左側頭皮的試驗為實施例，試驗區1之被實驗者之左側頭皮及試驗區2之被實驗者之右側頭皮的試驗為比較例。 〔評價〕 針對試驗區1之被實驗者及試驗區2之被實驗者評價以下狀態，即：(a)即將實施第1處理前之右側頭皮之頭皮環境狀態；(b)剛實施第1處理後之右側頭皮之頭皮環境狀態；(c)即將實施第2處理前之左側頭皮之頭皮環境狀態；及(d)剛實施第2處理後之左側頭皮之頭皮環境狀態。 將試驗區1之被實驗者之(a)及試驗區2之被實驗者之(c)之各值的平均值設定為實施例(處理前)之值，將試驗區1之被實驗者之(b)及試驗區2之被實驗者之(d)之各值的平均值設定為實施例(處理後)之值。又，將試驗區1之被實驗者之(c)及試驗區2之被實驗者之(a)之各值的平均值設定為比較例(處理前)之值，將試驗區1之被實驗者之(d)及試驗區2之被實驗者之(b)之各值的平均值設定為比較例(處理後)之值。實施例及比較例之各值係採平均值。 在以下〔1〕～〔4〕中列舉實施例(處理前)、實施例(處理後)、比較例(處理前)及比較例(處理後)之評價項目。 〔1〕頭皮之水分量 使用經皮水分蒸散量測定器(「Tewameter TM 300」，Courage+Khazaka electronic社製)來測定頭皮之水分蒸散量(g/(m2
・hr))。將各被實驗者之結果予以平均，並將其作為評價結果。 〔2〕頭皮之油分量 使用油分計(「Sebumeter SM815」，Courage+Khazaka electronic社製)來測定頭皮之皮脂分泌量(μg/cm2

In the embodiments described below, the same or the same portions are denoted by the same reference numerals, and the description thereof will not be repeated. (Embodiment 1) First, the configuration of the scalp environment improvement device of Embodiment 1 will be described. 1 to 3, the scalp environment improving device includes a cylindrical casing 1, a grip 2, and a scalp contact 3. A suction port 11 and an air outlet 12 are formed at one end and the other end of the cylindrical casing 1. Inside the casing 1, an internal space is formed which can form a flow of air from the suction port 11 toward the air outlet 12. Further, a charged particle generating portion 13 and a blowing portion 14 are disposed inside the casing 1. Further, a heater 15 and a control unit 16 are disposed inside the casing 1. The charged particle generating unit 13 is for causing a charged particle generator. Specifically, the charged particle generating unit 13 includes two pairs of needle-shaped discharge electrodes and two pairs of annular dielectric electrodes (not shown) surrounding the discharge electrodes. In the charged particle generating portion 13, a corona discharge is generated by applying a voltage between the discharge electrode and the dielectric electrode. Positive ions and negative ions are generated around the discharge electrode by the corona discharge. Positive ion system H + (H 2 O) m (m is an arbitrary natural number), negative ion system O 2- (H 2 O) m (m is an integer containing any of 0). The blower unit 14 is configured to send charged particles from the air outlet 12 toward the outside of the casing 1, and to generate a flow of air from the suction port 11 toward the air outlet 12. In the present embodiment, the air blowing portion 14 as the axial flow fan is exemplified, but the present invention is not limited thereto. As shown in FIG. 3, each of the above-described portions is provided with a suction port 11, a blower portion 14, a charged particle generating portion 13, and an air outlet 12 in this order from the suction port 11 toward the air outlet 12. The heater 15 is for heating the air in the vicinity of the heater 15. The heater 15 is disposed at least between the air blowing portion 14 and the air outlet 12, and is preferably disposed between the charged particle generating portion 13 and the air blowing portion 14. The configuration of the heater 15 is not particularly limited, and for example, a configuration in which a heating wire is wound around a support plate disposed in the casing 1 can be exemplified. The control unit 16 is electrically connected to the charged particle generating unit 13, the air blowing unit 14, the heater 15, and an operation unit 21 which will be described later. Thereby, the operation unit 21 can control the operations of the charged particle generating unit 13, the air blowing unit 14, and the heater 15 in accordance with the received operation from the user. The grip 2 is a portion that is held by the user in order to make it easy for the user to use the scalp environment improving device. In the present embodiment, the grip portion 2 is provided with an operation portion 21 for the user to operate the scalp environment improving device. Further, a power cord (not shown) is connected to the grip 2. Thereby, the scalp environment improving device can be electrically connected to the external power source. The scalp contact body 3 is disposed outside the casing 1. In the first embodiment, the contact portion (the front end portion of the rod portion 31 in FIG. 2) at least in contact with the scalp of the user in the scalp contact body 3 is located at the outlet from the outlet 12 to the outside of the casing 1. Inside the flow of particles. Therefore, the scalp contact body 3 is disposed between the air outlet 12 and the scalp, in other words, on the side of the suction port 11 disposed outside the casing 1, but on the side of the air outlet 12. In the present embodiment, the scalp contact body 3 has a plurality of rod-shaped portions 31. The front end portion of the rod portion 31 serves as a contact portion that comes into contact with the scalp of the user. Such a scalp contact body 3 has a first function of giving a comfortable stimulation to the scalp, and by squeezing the hair on the scalp and floating it from the scalp, thereby exposing the scalp to the external environment and making the scalp under the hair The second function that is easily in contact with the charged particles sent out from the air outlet 12. The scalp contact body 3 can be integrally formed with the housing 1, and can also be constructed in a detachable manner. In the case of a separable structure, for example, as shown in FIG. 3, it is preferable that the casing 1 is provided with a loading and unloading switch 17 that makes it possible to attach and detach the scalp contact body 3. The detachable switch 17 can be pressed, for example, when the scalp contact body 3 is attached to the casing 1, and is not pressed when the scalp contact body 3 is not attached to the casing 1. 2 shows a state in which the scalp contact body 3 is attached to the casing 1, and FIG. 4 shows a state in which the scalp contact body 3 is not attached to the casing 1. Further, by electrically connecting the detachable switch 17 and the control unit 16, the attachment operation of the scalp contact body 3 can be interlocked with the operation of each unit. For example, in a case where the loading and unloading switch 17 is pressed (in the case where the scalp contact body 3 is attached to the casing 1), the driving of the heater 15 or the heating by the heater 15 can be prohibited by the control portion 16. The degree is controlled to be low. Further, when the detachable switch 17 is not pressed (when the scalp contact body 3 is not attached to the casing 1), the control unit 16 permits the driving of the heater 15 or the like. According to the interlocking operation as described above, for example, in the case where the scalp contact body 3 is attached to the scalp environment improving device, the temperature of the air supplied to the scalp can be prevented from becoming excessively high. Such a scalp environment improving device can have hair drying using a relatively high temperature warm air in a state where the scalp contact body 3 is not attached, and a scalp care which is relatively low in temperature in a state in which the scalp contact body 3 is attached. . When the scalp care is performed, the distance between the air outlet 12 and the scalp is higher than the distance between the air outlet 12 and the scalp when the hair is dried. In the state where the distance is short, if the temperature of the air sent out from the air outlet 12 is too high, there is a risk of damage to the scalp such as burns. However, according to the above configuration, such damage can be prevented. The scalp environment improving device of the first embodiment operates as follows. First, a power cord (not shown) extending from the grip 2 is connected to an external power source. Further, in a case where the scalp contact body 3 and the casing 1 are detachably connected, the scalp contact body 3 is attached to the casing 1 in advance. Next, the operation portion 21 is operated in a state where the rod portion 31 of the scalp contact body 3 is in contact with the scalp of the user. The operation accepted by the operation unit 21 is transmitted to the control unit 16. The control unit 16 drives the charged particle generating unit 13 and the blower unit 14 in accordance with the operation accepted by the operation unit 21. The air is blown by the air blowing unit 14 to generate a flow of air from the suction port 11 toward the air outlet 12 in the casing 1. Further, by the charged particle generating unit 13, the charged particles are generated in the casing 1. The generated charged particles are carried out from the air outlet 12 to the outside by the flow of the air generated by the air blowing portion 14. The charged particles sent out to the outside gradually spread. Here, the front end portion of the rod portion 31 in contact with the scalp is located in the flow path of the charged particles. Therefore, a large number of charged particles sent to the outside of the casing 1 can go to the vicinity of the front end portion of the rod portion 31. Further, as described above, the scalp contact body 3 has a second function of easily contacting the scalp under the hair with the charged particles sent from the air outlet 12 by pulling the hair on the scalp and floating it from the scalp. . Therefore, the charged particles sent to the vicinity of the front end portion of the rod portion 31 can effectively reach the scalp exposed near the front end portion. As described in detail above, according to the scalp environment improving device of the first embodiment, the scalp can be comfortably stimulated by the first function of the front end portion of the rod portion 31. Further, by the second function of the distal end portion, the scalp in the vicinity of the distal end portion can be exposed to the outside, whereby the charged particles can be efficiently brought to the scalp exposed to the outside. The scalp environment is improved on the scalp that is given the comfort stimulus and the majority of the charged particles reach. Specific examples of the improvement of the scalp environment include (1) suitably maintaining the moisture content of the scalp; (2) appropriately maintaining the oil content of the scalp; and (3) the state of the scalp perceived by the user is comfortable; 4) inhibiting the reproduction of Malassezia; and (5) promoting hair growth and hairiness of hair. If at least one of these is improved, it can be considered that the scalp environment is improved. For example, in the above (1), in the case where the moisture content of the scalp of the epidermis is too low, the barrier function of the scalp (the function of the scalp itself which suppresses scalp damage caused by external stimuli) is lowered. This department's scalp environment is in a bad state. In general, it is considered that if the skin's ceramide and hyaluronic acid are insufficient, the moisturizing power of the skin is lowered to cause wrinkles and slack, but the barrier function of the skin is also a cause. Therefore, the above (1) is one of the improvements in the scalp environment. In particular, in the case where most of the charged particles reach the scalp, it can be considered that the surface of the scalp is covered by the charged particles, and the evapotranspiration of the moisture from the scalp is suppressed. Further, in the above (2), in the case where the oil content of the scalp of the epidermis is too low, the scalp environment is in a poor state as in the case where the moisture content is too low. This is because the sebaceous scalp is used as a factor in the function of the barrier, and if it is insufficient, the barrier function of the scalp is lowered. Therefore, the above (2) is one of the improvements in the scalp environment. In particular, in the case where most of the charged particles reach the scalp, it can be considered that the surface of the scalp is covered by the charged particles, and the excessive loss of the oil from the scalp is suppressed. Furthermore, the amount of oil in the scalp is also high in the case where the amount of oil in the scalp is too high, and it is also a state in which the scalp environment is not good. This is due to the stickiness and odor of the scalp. Further, regarding the above (3), the state in which the user feels that the state of the scalp is comfortable is relatively important, but it is considered to be an important factor. For example, feeling the softness of the scalp, or feeling the warmth of the scalp, can be said to be an improvement of the scalp environment. As an improvement of other scalp environments, for example, it is felt that, for example, the hair volume is increased, and the reduction of each of the following is felt, that is, the degree of mindfulness of hair loss, the degree of mindfulness of dandruff, the degree of mindfulness of scalp itching, The degree of mindfulness of white hair (feeling the degree of white hair), the degree of scent of the scalp, the degree of mindfulness of the scalp (feeling the degree of segregation), and the degree to which the head is heavy. Further, regarding the above (4), Malassezia is often bacteria on the skin, but if it is excessively propagated, it causes dandruff and itching of the scalp. This department's scalp environment is in a bad state. Therefore, the above (4) is one of the improvements in the scalp environment. Further, in the above (5), if the degree of hair growth and hairiness of the hair is lowered, the hair is sparse. Hair thinning is generally undesired, and even if hair is considered to have a function of protecting the scalp, hair thinning is also a poor condition for the scalp environment. Therefore, it can be said that the above (5) is one of the improvement of the scalp environment. According to the scalp environment improving device of the present embodiment, it is possible to improve the scalp environment as described above. The reason can be inferred as follows. For example, in the case of a hair dryer having only a charged particle generating portion, although the wind containing the charged particles is sent from the hair dryer toward the hair, it is difficult to send it toward the scalp. The reason is that since the scalp is usually covered with hair, if only the wind containing the charged particles is simply sent toward such a scalp, most of the charged particles are consumed on the surface of the hair, and as a result, it is difficult to obtain a sufficient amount of charged particles to reach the scalp. . Further, even if the comb is attached to the outlet side of the blower, the comb has only a configuration for combing the hair. Therefore, it is difficult to sufficiently lift the hair from the scalp and expose the scalp to the external environment. On the other hand, the scalp environment improving device of the present embodiment includes the scalp contact body 3, which has the first function of giving a comfortable stimulation to the scalp as described above, and is made to float the hair on the scalp and float it from the scalp. Therefore, the second function of the scalp under the hair and the charged particles sent out from the air outlet 12 are easily contacted. Therefore, in the case where the scalp environment improving device is used for the scalp covered with hair, the scalp can be appropriately stimulated while the scalp to which the stimulation is given is exposed to the outside. Therefore, the provision of a comfortable stimulus and the introduction of a sufficient amount of charged particles can be simultaneously performed on the scalp. It is contemplated that a sufficient amount of charged particles will reach the scalp that is suitably stimulated, the scalp maintains a suitable amount of water, and maintains a suitable amount of oil. Further, along with this, the state of the scalp that the user can feel is comfortable. Further, it is expected that the growth of Malassezia can be inhibited by a sufficient amount of charged particles reaching the scalp which is suitably stimulated. Further, it is also expected to cause hair growth and hair growth by a sufficient amount of charged particles to reach the scalp which is suitably stimulated. In the scalp environment improving device of the first embodiment described above, preferably, the distance between the front end portion (one portion in contact with the scalp) of the rod portion 31 of the scalp contact body 3 and the air outlet 12 is 15 cm or less. Thereby, the charged particles can be reached to the scalp at a higher concentration. However, in this case, it is necessary to pay attention to the temperature of the supply air reaching the scalp. Specifically, in order to make the temperature of the air blown to the scalp 55 ° C or lower, it is preferably controlled by the control unit 16 . Further, the above distance is a linear distance between the air outlet 12 and the front end portion of the rod portion 31, and is the shortest straight line distance. This distance is 10 cm or more in composition. Further, in the scalp environment improving device of the first embodiment, the ion concentration sent from the charged particle generating unit 13 is preferably a total of 3.3 million positive/negative ions and negative ions. 3 the above. At 3.3 million / cm 3 In the above case, the above-described improvement effect of the scalp environment can be further improved. Further, the ion concentration is a value measured from a position away from 15 cm in the direction in which the air is sent out from the air outlet 12. The measurement of ions can be performed using an ion counter. Further, in the scalp contact body 3 of the first embodiment, it is preferable that at least two or more rod-shaped portions 31 are provided from the viewpoint of having a second function as appropriate. In this case, when the number of the rod-shaped portions 31 is one, there is a possibility that the behavior of combing the hair from the scalp cannot be sufficiently performed. Further, from the viewpoint of suitably having the first function, the rod-like portion 31 is preferably curved in a bowl shape in the longitudinal direction. This is because the rod portion 31 is bent into a bowl shape, and the excess force can be released as compared with the straight line structure, giving the scalp a more comfortable stimulation. Further, the rod portion 31 may have a second function as long as it is bent into a bowl shape in the longitudinal direction. This is because the rod portion 31 has a portion which is in the shape of a bowl, and the hair can be lifted from the scalp more suitably in this portion. Further, in the scalp environment improving device of the first embodiment, it is preferable that at least the front end portion of the rod portion 31 is located in the flow path of the charged particles in the scalp contact body 3, and is disposed outside the flow path. nearby. Here, the flow path for the charged particles and the vicinity of the outer periphery of the flow path will be described with reference to Fig. 5 . Fig. 5 is a schematic perspective view for explaining the outer diameter of the air outlet. First, the outer diameter (the area indicated by a broken line in Fig. 5) of the air outlet 12 when the air outlet 12 is visually viewed from the outside is regarded as an exhaust surface (a region surrounded by a broken line in Fig. 5). In Figure 5, the exhaust surface is missing a portion of the circle. A cylindrical region in which the exhaust surface is continuously moved in parallel from the blower outlet 12 toward the outer side of the casing 1 is regarded as a flow path of charged particles. In addition, it goes without saying that the charged particle system is discharged toward the outside while diffusing toward the square. In addition, the vicinity of the center of the flow path means the vicinity of the center in the direction in which the flow path extends (the direction in which the air outlet 12 extends toward the outer side of the casing 1), and the vicinity of the flow path It means that it is near the outer circumference in the case where the flow path is extended from the direction in which the flow path extends. It is preferable that the front end portion of the rod portion 31 is disposed near the center of the flow path of the charged particles, and the vicinity of the outer periphery is preferable. The charged particles are sent out while being diffused toward the outside from the air outlet 12. Therefore, the concentration of the charged particles in the vicinity of the outer periphery of the flow path tends to be lower than the concentration of the charged particles in the vicinity of the center in the flow path. On the premise of the above, it is assumed that the front end portion of the rod portion 31 is disposed near the center of the flow path of the charged particles. In this case, when the scalp contact body 3 is moved (for example, about 10 cm) in a state where the scalp contact body 3 is brought into contact with the scalp, the scalp exposed to the outside becomes the position at which the front end portion is currently in contact with and from the position. Deviate from the scalp between 10 cm. At this time, there is a deviation between the position near the center where the high-concentration charged particles exist and the position of the scalp exposed to the outside. The reason for this is that the position at which the front end portion is currently in contact is near the center of the flow path. On the other hand, it is assumed that the front end portion of the rod portion 31 is disposed in the vicinity of the outer circumference of the flow path of the charged particles. In this case, the deviation between the position near the center of the flow path where the charged particles having a high concentration exists and the position of the scalp exposed to the outside become smaller than the above case. The reason for this is that the position at which the front end portion is currently in contact is near the outer circumference of the flow path, and the position of the scalp exposed to the outside in the vicinity thereof can be near the center of the flow path. Therefore, the front end portion of the rod portion 31 is disposed in the vicinity of the center of the flow path of the charged particles, and the charged particles can be introduced more efficiently to the scalp exposed to the outside. (Embodiment 2) The second embodiment differs from the first embodiment in that the scalp environment improving device further includes a cover. In the present embodiment, differences from the first embodiment will be described, and the description will not be repeated. Fig. 6 is a perspective view showing the scalp environment improving device of the second embodiment. As shown in FIG. 6, the scalp environment improving device further includes a cover 4 that surrounds the scalp contact body 3. The cover 4 has a function of forming a flow path for guiding the charged particles sent out from the air outlet 12 to the scalp which is in contact with the scalp contact body 3. Specifically, the cover 4 is connected to the air outlet side end portion 41 of the air outlet 12 and a substantially cylindrical shape that opens toward the outer side end portion 42 of the air outlet 12 . In particular, the region surrounded by the cover 4 from the outlet side end portion 41 toward the outer side end portion 42 has a shape that greatly expands. The cover body 4 having such a configuration can effectively guide the air containing the charged particles sent out from the air outlet 12 to the outside before the rod portion 31 of the scalp contact body 3, without hindering the function of the scalp contact body 3. End of the wind. The cover 4 may be integrally formed with the scalp contact body 3 as shown in FIG. 6, or may be formed separately as a member different from the scalp contact body 3. If there is no cover 4, the air containing the charged particles can freely diffuse between the air exiting the outlet 12 and the scalp. Therefore, the concentration of charged particles reaching the scalp (units/cm) 3 The concentration of charged particles that have just been sent out to the outside from the outlet 12 (pieces/cm) 3 ) becomes smaller. On the other hand, according to the scalp environment improving device including the cover 4, the air containing the charged particles sent from the air outlet 12 is guided into the air passage formed by the cover 4, and reaches the vicinity of the end portion of the air passage. scalp. In this case, a higher concentration of charged particles can be reached to the scalp as compared with a case where air containing charged particles is freely diffused from the time when the air outlet 12 reaches the scalp. (Embodiment 3) The present embodiment 3 is a scalp environment improvement method using the scalp environment improvement device of the first embodiment or the second embodiment. This scalp environment improving method is a method of feeding charged particles toward the scalp in a state where the scalp contact body 3 is in contact with the scalp. Fig. 7 is a schematic view showing a state in which the scalp environment improvement method of the third embodiment is carried out. Fig. 8 is a schematic view showing a state in the vicinity of the scalp in the scalp environment improving method of the third embodiment. In the present embodiment, a scalp environment improving device is used as shown in FIG. Thereby, as shown in FIG. 8, the scalp contact body 3 can be brought into contact with the scalp M. As described above, the scalp contact body 3 has the first function of providing comfort to the scalp, and the scalp under the hair and the self-blowing outlet 12 by pulling the hair on the scalp and lifting it from the scalp. The second function of the charged particles that are easily accessible. Thereby, the scalp can be efficiently stimulated to efficiently reach the scalp, so that the above-described scalp environment can be improved. In the above method, for example, the front end portion is moved on the scalp while the front end portion of the rod portion 31 of the scalp contact body 3 of the scalp environment improving device is in contact with the scalp. At this time, the movement is preferably set to the speed and intensity at which the stimulation caused by the end portion of the scalp is moved forward to the extent that the user feels comfortable. With the above movement, the hair grown on the scalp which is moved at the front end portion becomes a state in which the scalp is floated. That is, the hair on the scalp of a larger area becomes a state of floating from the scalp as compared with the case where the front end portion is not moved. Thereby, it is possible to expand the area in the scalp where the charged particles are efficiently reached. Moreover, with this movement, the scalp can be given a more comfortable stimulation. [Examples] The present invention will be more specifically described below by showing examples and comparative examples, but the present invention is not limited thereto. (Study 1) Six women over the age of 40 and under 65 years of age were randomly assigned to test area 1 and test area 2, and a double-blind cross test was performed. Machine A and Machine B were used in the implementation of the test. Machine A is a machine according to an embodiment, which corresponds to the scalp environment improvement device of the first embodiment. The machine B is a control device for a comparative example, and corresponds to a device in which the charged particle generating unit 13 is removed from the scalp environment improving device of the first embodiment. [Test] The first treatment of the right scalp of the subject of the test area 1 was carried out by a third person (inspection worker) different from the subject. Specifically, the right side scalp of the subject in the test area 1 is operated 60 times or less, that is, in a state where the front end portion of the rod portion provided in the machine A is in contact with the scalp, the front end portion is made from the head portion. After the front side moved toward the back of the head for 3 seconds, the front end portion was removed from the scalp for 2 seconds. Thereby, the scalp of the entire right side of the subject in the test area 1 was subjected to stimulation by the rod portion for 5 minutes and air supply by the warm air containing the charged particles. After the above operation is completed, the time interval in which the subject is in a quiet state is performed for 60 minutes. After the end time interval, the second treatment of the left scalp of the subject was performed. The second treatment of the left scalp is set to be the same as the first treatment for the right scalp except that the machine B is used instead of the substitute machine A. Thereby, the scalp on the left side of the subject in the test area 1 was subjected to a stimuli caused by the rod portion and a warm air (excluding charged particles) for 5 minutes. Table 1 shows the setting conditions for the use of machine A and machine B. Further, the temperature in Table 1 was measured by a thermometer placed at a position 15 cm away from the outlet. [Table 1] As described above, in the subject of the test area 1, the first process using the machine A was performed on the entire right scalp, and the second process using the machine B was performed on the entire left scalp. On the other hand, in each of the subjects in the test area 2, the machine B was used in the first process for the right scalp, and the machine A was used in the second process on the left scalp, and the test was performed in the same manner as the above test. test. That is, the test of the right side scalp of the subject in the test area 1 and the left side scalp of the test subject of the test area 2 is an example, the left side scalp of the test subject 1 and the right side of the test subject of the test area 2 The test of the scalp is a comparative example. [Evaluation] The subjects in the test area 1 and the subjects in the test area 2 were evaluated as follows: (a) the scalp environment state of the right scalp immediately before the first treatment; (b) the first treatment was performed. The scalp environment state of the right scalp after the second scalp; (c) the scalp environment state of the left scalp immediately before the second treatment; and (d) the scalp environment state of the left scalp immediately after the second treatment. The average value of each of the (a) of the test subject 1 and the test subject 2 (c) is set to the value of the example (before treatment), and the test subject 1 is tested. (b) The average value of each value of (d) of the test subject 2 is set to the value of the example (after treatment). Further, the average value of each of the values of (a) of the subject (c) of the test area 1 and the test subject 2 was set to the value of the comparative example (before treatment), and the test area 1 was tested. The average value of each value of (b) and the subject (b) of the test area 2 is set to the value of the comparative example (after treatment). The values of the examples and comparative examples were averaged. The evaluation items of the examples (before the treatment), the examples (before the treatment), the comparative examples (before the treatment), and the comparative examples (after the treatment) are listed in the following [1] to [4]. [1] Moisture content of the scalp The amount of water evapotranspiration of the scalp was measured using a transdermal moisture evapotranometer ("Tewameter TM 300", Courage+Khazaka electronic Co., Ltd.) (g/(m 2 ・hr)). The results of the subjects were averaged and used as the evaluation results. [2] Oil content of the scalp The sebum secretion amount (μg/cm) of the scalp was measured using an oil content meter ("Sebumeter SM815", manufactured by Courage+Khazaka electronic Co., Ltd.). 2 ). The results of the subjects were averaged and used as the evaluation results. [3] Sensory evaluation 1: Softness of scalp Regarding the softness of the scalp, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. The evaluation criteria at this time are as follows. Before and after the treatment, each subject showed a position on the evaluation bar indicating only the lower limit and the upper limit, and the position of each subject was considered to be "feeling that the scalp was soft". Next, unlike the result of the third person of the subject, the values of the lower limit and the upper limit of the evaluation bar are set to "0" and "100", and the positions of the respective markers are digitized, and the processing is calculated. The average of the previous values and the average of the values after processing. [4] Sensory evaluation 2: Warmness of scalp Regarding the warmth of the scalp, the sensory evaluation of each experimenter was carried out, and the average was used as the evaluation result. The evaluation criteria at this time are as follows. Before and after the treatment, each of the subjects indicated on the evaluation bar indicating only the lower limit and the upper limit, and the position corresponding to "feeling that the scalp is gradually warming". Next, unlike the result of the third person of the subject, the values of the lower limit and the upper limit of the evaluation bar are set to "0" and "100", and the positions of the respective markers are digitized, and the processing is calculated. The average of the previous values and the average of the values after processing. Next, the value (average value) obtained from the obtained treatment is subtracted from the value (average value) before the obtained treatment. [Evaluation Results] The evaluation results of the above [1] to [4] are shown in Figs. 9 to 12 . The error bars displayed on the bars of Figures 9 to 12 mean standard errors. Fig. 9 is a graph showing the evaluation results of the moisture content of the scalp of Study 1. In the comparative example, the degree of reduction in the amount of moisture evapotranspiration was low by the treatment, and there was no significant difference after the treatment. On the other hand, in the examples, the degree of reduction in the amount of moisture evapotranspiration was large by the treatment, and it was confirmed that there was a significant difference (p < 0.05) before and after the treatment. From this, it is understood that in the examples, the amount of water evapotranspiration of the scalp was small as compared with the comparative example, and the scalp was maintained in an appropriate state. In addition, the Wilcoxon signed rank test was used in the calculation of the p value. Fig. 10 is a graph showing the results of the oil component of the scalp of Study 1. In the comparative example, the amount of sebum secretion was greatly reduced by the treatment, and the p value before and after the treatment was p < 0.2. Further, it was found that the amount of sebum secretion after the treatment of the comparative example was extremely low, and it was impossible to maintain a suitable oil content of the scalp. On the other hand, in the examples, the degree of reduction in the amount of sebum secretion was small by the treatment. Further, the p value of the difference between the difference between the difference before and after the treatment of the comparative example and the difference between the treatments of the examples was p < 0.05. From this, it is understood that in the examples, the oil content of the scalp was higher than that of the comparative example, so that the scalp was maintained in an appropriate state. In addition, the Wilcoxon signed rank test was used in the calculation of the p value. Figure 11 is a graph showing the results of Sensory Evaluation 1 of Study 1. In the comparative example, there was no change in the evaluation before and after the treatment. On the other hand, in the examples, the evaluation of the degree of "feeling that the scalp was soft" before the treatment was higher than that before the treatment, and there was a significant difference (p < 0.05) after the treatment was confirmed. From this, it can be seen that in the examples, the scalp was perceived to be softer than the comparative example, and the scalp was maintained in an appropriate state. In addition, a corresponding t-test is used in the calculation of the p-value. Figure 12 is a graph showing the results of Sensory Evaluation 2 of Study 1. The difference between before and after the treatment of the examples was larger than that before and after the treatment of the comparative examples. Further, the p value of the difference between the difference between the difference before and after the treatment of the comparative example and the difference between the treatments of the examples was p < 0.2. From this, it can be seen that in the examples, as compared with the comparative example, the scalp is more strongly felt by the treatment, and the scalp is maintained in an appropriate state. In addition, a corresponding t-test is used in the calculation of the p-value. (Study 2) 59 women over the age of 60 and under 65 were selected as the subjects, and 29 randomly selected were assigned to group A, and 30 randomly selected were assigned to group B, and a double-blind parallel group was implemented. Comparison test. Machine A and Machine B identical to Study 1 were used in the practice of the test. Machine A is used for Group A and Machine B is used for Group B. [Test] After the subject of the group A shampooed and dried at home, the first treatment was performed using the machine A. Specifically, the subject himself performs 60 times of the operation of shampooing and drying the top of his head, that is, in a state where the front end portion of the rod portion provided in the machine A is in contact with the scalp, The front end portion was moved from the front of the top of the head toward the rear of the head for 3 seconds, and the front end portion was removed from the scalp for 2 seconds. Thereby, the scalp on the top of the head of the subject in the group A was subjected to stimulation by the rod portion for 5 minutes and air supply by the warm air containing the charged particles. The subjects in Group A performed the above tests every day for 12 weeks. The tester of group B used machine B instead of machine A, and performed the same test as the tester of group A every day for 12 weeks. [Evaluation] The evaluation items of Study 2 are listed in the following [5] to [15]. [5]~[7] are inspected by the inspection staff before the start of the test (week 0), after 4 weeks from the start of the test, after 8 weeks, and after 12 weeks. Evaluation. [8]~[15] In each of the inspection institutions, each test was performed immediately before the start of the test (week 0), after 4 weeks from the start of the test, after 8 weeks, and after 12 weeks. Evaluation. [5] Water content of the scalp The amount of water evapotranspiration of the scalp of each subject in each group was measured by the same method as the above [1] (g/(m) 2 ・hr)). [6] Oil content of scalp The sebum secretion amount (μg/cm) of the scalp of each subject in each group was measured by the same method as the above [2]. 2 ). [7] The number of Malassezia in the scalp is rubbed from the machine A by using a sterilized cotton swab ("cotton stick hospital cotton swab (0-319-32)" manufactured by AS ONE Co., Ltd.). The scalp in the area where the wind is sent by the machine B is immersed in a solution of a seed tube ("seed tube (9-MR84)", manufactured by Eiken Chemical Co., Ltd.). The solution in the seed tube was used as a sowing liquid, and the seeding liquid was sown in an amica culture medium ("CHROMager (registered trademark) Marathon / Candida medium, Kanto Chemical Co., Ltd.) and cultured. After the cultivation, the number of Malassezia on the acacia medium was measured, and the number of Malassezia in each subject of each group was evaluated. In addition, the measurement of the number of Malassezia was carried out by LSI Medience Co., Ltd. [8] Sensory evaluation 3: Hair volume The amount of hair was measured, and the sensory evaluation of each subject was performed, and the average was used as the evaluation result. The evaluation criteria at this time are as follows. Each of the subjects indicated on the evaluation bar indicating only the lower limit and the upper limit, and the position of each subject to measure the degree of "feeling the increase in hair volume". Next, the inspection staff set the values of the lower limit and the upper limit of the evaluation bar to "0" and "100" for each of the subjects, and numerically quantify the positions of the respective indicators, and calculate each of the A group and the B group. average value. [9] Sensory evaluation 4: Degree of hair loss About the degree of hair loss, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. In this case, the evaluation method is set to the same method as the above [8] except that the index of the evaluation stick is changed to "the degree of intentional hair loss". [10] Sensory evaluation 5: Degree of dandruff About the degree of dandruff, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. In this case, the evaluation method is set to the same method as the above [8] except that the index of the evaluation stick is changed to "the level of mind dandruff". [11] Sensory evaluation 6: The degree of itching of the scalp about the degree of itching of the scalp, and the sensory evaluation of each subject was performed, and the average was used as the evaluation result. In this case, the evaluation method is the same as the above [8] except that the index of the evaluation stick is changed to "the degree of itchiness of the scalp". [12] Sensory evaluation 7: Degree of white hair Regarding the degree of white hair, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. In this case, the evaluation method is set to the same method as the above [8] except that the index of the evaluation stick is changed to "the degree of mindfulness of white hair". [13] Sensory evaluation 8: The odor of the scalp The degree of odor of the scalp was evaluated by the sensory evaluation of each subject, and the average was used as the evaluation result. In this case, the evaluation method is the same as the above [8] except that the index of the evaluation stick is changed to "the odor of the scalp". [14] Sensory evaluation 9: The degree of the slit of the hair was determined by the sensory evaluation of each subject, and the average was used as the evaluation result. In this case, the evaluation method is the same as the above [8] except that the index of the evaluation stick is changed to "the degree of separation of the hair". [15] Sensory evaluation 10: The severity of the head is heavy. The sensory evaluation of each subject is performed, and the average is used as the evaluation result. In this case, the evaluation method is set to the same method as the above [8] except that the index of the evaluation stick is changed to "the feeling that the head is heavy". [Evaluation Results] The evaluation results of the above [5] to [15] are shown in Figs. 13 to 23 . The error bars shown on the bars of Figures 13, 14, 16-23 mean standard errors. Fig. 13 is a graph showing the results of evaluation of the amount of moisture evapotranspiration of the scalp of Study 2. The whitening bar (Example) is the amount of change in the amount of water evapotranspiration of the scalp of the subject in Group A, and is the average of the values of the subjects from the value of the 12th week minus the value of the 0th week. value. The bars indicated by the shaded hatching (comparative example) are the amounts of change in the amount of moisture evapotranspiration of the scalp of the subjects in Group B, and are values obtained by subtracting the value of Week 0 from the value of the 12th week of each subject. The average value. In group A, the amount of change in moisture evapotranspiration was negative. That is, in the examples, the amount of water evapotranspiration of the scalp at the 12th week was smaller than that of the scalp at the 0th week. On the other hand, in the group B, the amount of change in the amount of moisture evapotranspiration was a positive value. That is, in the comparative example, the amount of water evapotranspiration of the scalp at the 12th week was larger than that of the scalp at the 0th week. Further, between the examples and the comparative examples, a significant difference (p < 0.05) was confirmed. From this, it is understood that the amount of water evapotranspiration of the scalp is smaller than that of the comparative example, and the scalp is maintained in an appropriate state. In addition, the U-test of Mann-Whitney was used for the calculation of the p value. Fig. 14 is a graph showing the evaluation results of the oil content of the scalp of Study 2. The white bars (Examples) are the oil content changes of the scalp of the subjects in Group A, and are the average values of the values of Week 8 minus the value of Week 0 for each subject. The bars indicated by the shaded hatching (Comparative Example) are the oil content changes of the scalp of the subjects in Group B, and are the average values of the values from the 8th week minus the 0th week of each subject. . The oil content changes of group A and group B were negative respectively, and the absolute value of group A was larger. That is, in the examples, the oil content of the scalp at the 8th week was significantly reduced with respect to the oil content of the scalp at the 0th week as compared with the comparative example. Further, between the examples and the comparative examples, a significant difference (p < 0.05) was confirmed. From this, it can be seen that in the examples and the comparative examples, the amount of oil in the scalp is largely reduced, so that the scalp is maintained in an appropriate state. In addition, the U-test of Mann-Whitney was used for the calculation of the p value. Fig. 15 is a graph showing the evaluation results of the number of Malassezia bacteria in Study 2. The broken line shown in the solid line (Example) is the transition from the 0th week of the number of Malassezia in the scalp of the test group of the group A, and is the 0th week, the 4th week, and the 8th week from the start of the test. The average of the number of changes in the number of Malassezia from the 0th week is linked. The fold line shown by the broken line (comparative example) is the transition from the 0th week of the number of Malassezia in the scalp of the subject of the B group, and is the 0th week, the 4th week, and the 8th week of the start of the test. The average of the changes in the number of Malassezia from the 0th week was linked. The number of Malassezia bacteria in Group A decreased significantly (approximately 64% reduction) after 8 weeks from the start of the test. In contrast, the number of Malassezia bacteria in Group B did not decrease significantly after 8 weeks from the start of the test. From this, it was found that the number of Malassezia scallops in the scalp was large as compared with the comparative example, and the scalp was maintained in an appropriate state. Fig. 16 is a graph showing the evaluation results of the sensory evaluation 3 of Study 2. The white bars (Examples) are the results of the sensory evaluation of the subjects in Group A (average values), showing the results of week 0 and the results of week 12. The bars (comparative examples) indicated by diagonal hatching are the results (average values) of the sensory evaluation of the scalp of the test group B, and the results of the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "feeling the increase in hair volume" was greater at the 12th week than at the 0th week, and in particular, the degree of the change of the embodiment was greater. Further, the p value of the comparison between the groups of the examples of the 12th week and the comparative examples was p < 0.1. From this, it is understood that in the examples, the hair growth amount tends to be increased as compared with the comparative example, and the scalp tends to be maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value. Fig. 17 is a graph showing the evaluation results of the sensory evaluation 4 of Study 2. The white bar (Example) is the result of the sensory evaluation of the subject of the group A, and is the value of the evaluation result of the 12th week from the value of the evaluation result of the 0th week of each subject. The average value. The bars indicated by the shaded hatching (comparative example) are the results of the sensory evaluation of the subjects in the group B, and the values of the evaluation results from the 12th week of each subject are subtracted from the values of the evaluation results of the 0th week. The average of the values. The average value of the change in the sensory evaluation of the group A (the amount of change in the VAS value) was about -15.0, whereas the average value of the amount of change in the VAS value of the group B was -7.0. Further, the p value of the comparison between the groups of the examples and the comparative examples was p < 0.2. From this, it can be seen that in the examples, compared with the comparative example, there is a strong tendency to reduce the degree of intentional hair loss, and the scalp tends to be maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value. In addition, the VAS system means the Visual Analogue Scale. Fig. 18 is a graph showing the evaluation results of the sensory evaluation 5 of Study 2. The white bars (Examples) are the results of the sensory evaluation of the subjects in Group A (average values), showing the results of week 0 and the results of week 12. The bars (comparative examples) indicated by diagonal hatching are the results (average values) of the sensory evaluation of the scalp of the test group B, and the results of the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "mining dandruff" was smaller at the 12th week than at the 0th week, and in particular, the degree of the change of the embodiment was greater. Further, the p value of the comparison between the groups of the examples of the 12th week and the comparative examples was p < 0.2. From this, in the examples, in comparison with the comparative examples, the degree of intentional dandruff was strongly suppressed, and the scalp was maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value. Fig. 19 is a graph showing the evaluation results of the sensory evaluation 6 of Study 2. The white bars (Examples) are the results of the sensory evaluation of the subjects in Group A (average values), showing the results of week 0 and the results of week 12. The bars (comparative examples) indicated by diagonal hatching are the results (average values) of the sensory evaluation of the scalp of the test group B, and the results of the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "inching of the scalp" was smaller at the 12th week than at the 0th week, and in particular, the degree of the change of the embodiment was greater. Further, the p value of the comparison between the groups of the Example and the comparative example at the 12th week was p < 0.05, and it was confirmed that there was a significant difference. From this, it can be seen that in the examples, the degree of itching of the scalp was strongly suppressed as compared with the comparative example, and the scalp was maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value. Fig. 20 is a graph showing the evaluation results of the sensory evaluation 7 of Study 2. The white bars (Examples) are the results of the sensory evaluation of the subjects in Group A (average values), showing the results of week 0 and the results of week 12. The bars (comparative examples) indicated by diagonal hatching are the results (average values) of the sensory evaluation of the scalp of the test group B, and the results of the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "mind white hair" at the 12th week was smaller than that of the 0th week, and in particular, the degree of the change of the embodiment was greater. Further, the p value of the comparison between the groups of the examples of the 12th week and the comparative examples was p < 0.1. From this, it can be seen that in the examples, compared with the comparative example, there is a strong tendency to reduce the degree of mindfulness of white hair, and thus the scalp tends to be maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value. Fig. 21 is a graph showing the evaluation results of the sensory evaluation 8 of Study 2. The white bars (Examples) are the results of the sensory evaluation of the subjects in Group A (average values), showing the results of week 0 and the results of week 12. The bars (comparative examples) indicated by diagonal hatching are the results (average values) of the sensory evaluation of the scalp of the test group B, and the results of the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "interesting odor of the scalp" was smaller at the 12th week than at the 0th week, and in particular, the degree of the change of the embodiment was greater. Further, the p value of the comparison between the groups of the examples of the 12th week and the comparative examples was p < 0.1. From this, it can be seen that in the examples, the degree of odor of the scalp is strongly suppressed as compared with the comparative example, and the scalp tends to be maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value. Fig. 22 is a graph showing the evaluation results of the sensory evaluation 9 of Study 2. The white bars (Examples) are the results of the sensory evaluation of the subjects in Group A (average values), showing the results of week 0 and the results of week 12. The bars (comparative examples) indicated by diagonal hatching are the results (average values) of the sensory evaluation of the scalp of the test group B, and the results of the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "intentional slitting" was smaller at the 12th week than in the 0th week, and in particular, the degree of the change of the embodiment was larger. Further, the p value of the comparison between the groups of the examples of the 12th week and the comparative examples was p < 0.1. From this, it can be seen that in the examples, compared with the comparative example, there is a tendency to feel that the degree of seizure is reduced, and the scalp tends to be maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value. FIG. 23 is a graph showing the evaluation results of the sensory evaluation 10 of Study 2. The white bar (Example) is the result of the sensory evaluation of the subject of the group A, and is the value of the evaluation result of the 12th week from the value of the evaluation result of the 0th week of each subject. The average value. The bars indicated by the shaded hatching (comparative example) are the results of the sensory evaluation of the subjects in the group B, and the values of the evaluation results from the 12th week of each subject are subtracted from the values of the evaluation results of the 0th week. The average of the values. The average value of the change in the sensory evaluation of the group A (the amount of change in the VAS value) was about -17.5, whereas the average value of the amount of change in the VAS value of the group B was about -8.0. Further, the p value of the comparison between the groups of the examples and the comparative examples was p < 0.1. From this, it can be seen that in the examples, compared with the comparative example, there is a strong tendency to feel that the head is heavy, and the scalp tends to be maintained in an appropriate state. In addition, a non-corresponding t test is used for the calculation of the p value.
