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 addition, in the embodiments shown below, the same or common parts are given the same reference numerals in the drawings, and descriptions thereof will not be repeated. (Embodiment 1) First, the structure of the scalp environment improvement apparatus of Embodiment 1 is demonstrated. As can be seen with reference to FIGS. 1 to 3, the scalp environment improving device includes a cylindrical casing 1, a grip 2, and a scalp contact body 3. A suction port 11 and a blowing port 12 are formed at one end and the other end of the cylindrical casing 1. An internal space is formed inside the casing 1 so that air can flow from the suction port 11 toward the blowout port 12. In addition, a charged particle generating section 13 and a blower section 14 are arranged inside the casing 1. Further, a heater 15 and a control unit 16 are arranged inside the casing 1. The charged particle generator 13 is a generator for generating a charged particle. Specifically, the charged particle generating section 13 includes two pairs of needle-shaped discharge electrodes and two pairs of circular-shaped dielectric electrodes (not shown) surrounding the discharge electrode. The charged particle generator 13 generates a corona discharge by applying a voltage between the discharge electrode and the dielectric electrode. This corona discharge generates positive and negative ions around the discharge electrode. Positive ion system H ＋ (H 2 O) m (m is any natural number), negative ion system O 2- (H 2 O) m (m is an arbitrary integer including 0). The air blowing unit 14 is used for sending out charged particles from the air outlet 12 toward the outside of the casing 1, and can generate a flow of air from the air inlet 11 toward the air outlet 12. In the present embodiment, the air blowing unit 14 as an axial flow fan is exemplified, but it is not limited to this. As shown in FIG. 3, each of the above-mentioned parts is arranged in this order from the suction port 11 toward the blow-out port 12. The heater 15 is used to warm the air near the heater 15. The heater 15 is arranged at least between the air blowing section 14 and the air outlet 12, and is preferably arranged between the charged particle generating section 13 and the air blowing section 14. The configuration of the heater 15 is not particularly limited. For example, a configuration in which a heating wire is wound on a support plate disposed in the housing 1 is exemplified. The control unit 16 is electrically connected to the charged particle generation unit 13, the air supply unit 14, the heater 15, and an operation unit 21 described later. Thereby, the operation section 21 can control the operations of the charged particle generating section 13, the air supply section 14, and the heater 15 in accordance with the operation received from the user. The grip 2 is a portion held by the user so that the user can easily use the scalp environment improving device. In this embodiment, the grip 2 is provided with an operation unit 21 for operating a scalp environment improving device by a user. A power cord (not shown) is connected to the grip 2. Thereby, the scalp environment improving device can be electrically connected to an external power source. The scalp contact body 3 is disposed outside the casing 1. In the first embodiment, at least the contact portion (the front end portion of the rod-shaped portion 31 in FIG. 2) of the scalp contact body 3 that is in contact with the scalp of the user is charged when it is sent from the blow-out port 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, the scalp contact body 3 is disposed not on the side of the suction port 11 in the outside of the casing 1 but on the air outlet 12 side. In the present embodiment, the scalp contact body 3 includes a plurality of rod-shaped portions 31. The front end portion of the rod-shaped portion 31 becomes a contact portion that comes into contact with the scalp of the user. In this way, the scalp contacting body 3 has a first function of providing a comfortable stimulus to the scalp and removing 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 is easy to contact with the charged particles sent from the self-blowing outlet 12. The scalp contact body 3 and the housing 1 may be formed integrally or may be configured in a detachable manner. In the case of a detachable structure, for example, as shown in FIG. 3, it is preferable that the housing 1 is provided with a detachable switch 17 that enables attachment and detachment of the scalp contact body 3. The attaching and detaching switch 17 may be in a pressed state when the scalp contact body 3 is attached to the case 1, and may be in an unpressed state when the scalp contact body 3 is not attached to the case 1. In addition, FIG. 2 shows a state where the scalp contact body 3 is mounted on the case 1, and FIG. 4 shows a state where the scalp contact body 3 is not mounted on the case 1. Furthermore, by electrically connecting the attachment / detachment switch 17 and the control unit 16, the mounting operation of the scalp contact body 3 can be linked with the operation of each unit. For example, when the attachment / detachment switch 17 is pressed (when the scalp contact body 3 is mounted on the housing 1), the control unit 16 can be used to prohibit the driving of the heater 15 or the heating by the heater 15 The degree is controlled to be low. In addition, when the attachment / detachment switch 17 is not pressed (when the scalp contact body 3 is not attached to the case 1), the control unit 16 may permit the driving of the heater 15 or the like. According to the interlocking operation as described above, for example, when the scalp contact body 3 is mounted on the scalp environment improving device, the temperature of the air supplied to the scalp can be prevented from becoming too high. In this way, the scalp environment improving device can have the functions of using relatively high-temperature hot air to dry the hair in a state where the scalp contact body 3 is not installed, and using a relatively low-temperature scalp care in a state where the scalp contact body 3 is installed . The distance between the air outlet 12 and the scalp when performing scalp care is more likely than the distance between the air outlet 12 and the scalp when the hair is dry. When the distance is short, if the temperature of the air sent from the air outlet 12 is too high, the scalp may be damaged due to burns, etc. 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. In a case where the scalp contact body 3 and the case 1 are detachable, the scalp contact body 3 is attached to the case 1 in advance. Next, the operation portion 21 is operated with the rod-shaped portion 31 of the scalp contact body 3 in contact with the scalp of the user. The operations accepted by the operation unit 21 are transmitted to the control unit 16. The control unit 16 drives the charged particle generating unit 13 and the air blowing unit 14 in accordance with the operation accepted by the operation unit 21. Driven by the air blowing unit 14, a flow of air from the suction port 11 toward the blowout port 12 is generated in the housing 1. The charged particles are driven by the charged particle generating unit 13 to generate charged particles in the housing 1. The generated charged particles ride on the flow of air generated by the air blowing unit 14 and are sent out from the blowing outlet 12 to the outside. The charged particles sent out to the outside gradually spread out. Here, the front end portion of the rod-shaped portion 31 in contact with the scalp is located in the flow path of the charged particles. Therefore, most of the charged particles sent out of the casing 1 can go to the vicinity of the front end portion of the rod-shaped portion 31. Furthermore, as described above, the scalp contacting body 3 has the second function of making the hair on the scalp lift off from the scalp and floating from the scalp, so that the scalp under the hair and the charged particles sent from the self-blowing outlet 12 can easily contact . Therefore, the charged particles sent out near the front end portion of the rod-shaped 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 first function of the front end portion of the rod-shaped portion 31 can be used to provide comfortable stimulation to the scalp. In addition, by utilizing the second function of the front end portion, the scalp near the front end portion can be exposed to the outside, thereby effectively bringing charged particles to the scalp exposed to the outside. On such a scalp that is given a comfortable stimulus and most of the charged particles reach, the scalp environment is improved. Specific examples of the improvement of the scalp environment include: (1) suitably maintaining the scalp's water content; (2) properly maintaining the scalp's oil content; (3) the state of the scalp that the user feels is comfortable; ( 4) Inhibit the reproduction of Malassezia; and (5) Promote hair growth and hair growth. If at least one of these is improved, it is considered that the scalp environment is improved. For example, regarding the above (1), when the moisture content of the scalp of the epidermis is too low, the barrier function of the scalp (the function of the scalp itself that suppresses scalp damage caused by external stimuli) is reduced. The scalp environment is in a poor state. Generally speaking, if ceramide and hyaluronic acid are insufficient in the skin, the skin's moisturizing power is reduced and wrinkles and sagging are caused, but the barrier function of the skin is also reduced. Therefore, it can be said that (1) is an improvement of the scalp environment. In particular, in the case where most charged particles reach the scalp, it can be considered that the surface of the scalp is covered with the charged particles to suppress the evapotranspiration from the scalp. Regarding the above (2), when the oil content of the scalp of the epidermis is too low, as in the case where the water content is too low, the scalp environment is in a poor state. This is because sebum is a factor used by the scalp to exert the barrier function. If it is insufficient, the barrier function of the scalp will be reduced. Therefore, it can be said that (2) is an improvement of the scalp environment. In particular, when most charged particles reach the scalp, it can be considered that the surface of the scalp is covered with the charged particles and the excessive loss of oil from the scalp can be suppressed. Furthermore, the oil content of the scalp is too high, and the scalp environment is not good. This is because it will become sticky and odorous to the scalp. Regarding the above (3), although it is relative that the state of the scalp felt by the user is comfortable, it is considered as an important factor. For example, feeling the scalp is soft, or feeling the scalp is warm, can be described as one of the improvements of the scalp environment. As another improvement of the scalp environment, for example, feeling the increase in hair volume and the decrease in each of the following, namely, the degree of mind for hair loss, the degree of dandruff, the degree of scalp itching, The degree of white hair (the degree of white hair being noticeable), the degree of odor of the scalp, the degree of subdivision of the scalp (degree of subtleness being noticeable), and the degree of heavy head. Regarding the above (4), although Malassezia is a skin resident bacteria, if it multiplies excessively, it may cause dandruff and itching of the scalp. The scalp environment is in a poor state. Therefore, it can be said that (4) is an improvement of the scalp environment. In addition, regarding the above (5), if the degree of hair growth and hair reduction is reduced, the hair becomes thinner. Thinning hair is generally a tendency not to be expected, and even considering that the hair has a function of protecting the scalp, thinning hair is not good for the scalp environment. Therefore, it can be said that (5) is one of the improvements of the scalp environment. According to the scalp environment improving device of this 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 section, although a wind system including charged particles is sent from the hair dryer toward the hair, it is difficult to send the wind toward the scalp. The reason is that the scalp is usually covered with hair. If only the wind containing charged particles is sent toward such a scalp, most of the charged particles are consumed on the hair surface. As a result, it is difficult to reach a sufficient amount of charged particles to the scalp. . In addition, even if a comb is attached to the blower outlet side of the hair dryer, the comb has only a structure for combing hair. Therefore, it is difficult to sufficiently lift the hair from the scalp and expose the scalp to the external environment. In contrast, the scalp environment improving device of the present embodiment includes the scalp contact body 3, which has the first function of providing a comfortable stimulus to the scalp as described above, and by removing the hair on the scalp and floating it from the scalp. The second function is to make it easy for the scalp under the hair to come into contact with the charged particles sent from the blow-out port 12. Therefore, when 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 stimulus is given is exposed to the outside. Therefore, it is possible to provide comfortable stimulation to the scalp and introduction of a sufficient amount of charged particles at the same time. It can be considered that with a sufficient amount of charged particles reaching the scalp that is suitably stimulated, the scalp can maintain a suitable amount of water and maintain a suitable amount of oil. With this, the state of the scalp that the user can feel is comfortable. Moreover, it is expected that a sufficient amount of charged particles reach the scalp that is suitably stimulated, and it is expected that the reproduction of Malassezia can be suppressed. Furthermore, when a sufficient amount of charged particles reach the scalp that is suitably stimulated, it is also expected that hair growth and hair promotion will be promoted. In the scalp environment improving device of the first embodiment described in detail above, the distance between the front end portion of the rod-shaped portion 31 of the scalp contact body 3 (a portion in contact with the scalp) and the air outlet 12 is preferably 15 cm or less. This allows the charged particles to reach 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 control the temperature of the blown air reaching the scalp to 55 ° C. or lower, it is preferably controlled by the control unit 16. The above-mentioned distance is a straight line distance between the blowout port 12 and the front end portion of the rod-shaped portion 31 and is the shortest straight line distance. This distance is 10 cm or more in structure. Further, in the scalp environment improving device of the first embodiment, it is preferable that the ion concentration sent from the charged particle generating unit 13 is 3.3 million / cm in total. 3 the above. 3.3 million pieces / cm 3 In the above circumstances, the improvement effect of the scalp environment described above can be further improved. In addition, the above-mentioned ion concentration is a value measured at a position away from 15 cm in the direction of the air flow sent from the blowing outlet 12. The ion measurement can be performed using an ion counter. Moreover, in the scalp contact body 3 of this Embodiment 1, it is preferable that the number of the rod-shaped parts 31 is at least 2 or more from a viewpoint of having a 2nd function suitably. This is because when the rod-shaped portion 31 is one, the action of combing hair from the scalp may not be sufficiently performed. From the viewpoint of having the first function as appropriate, the rod-shaped portion 31 is preferably curved in a bowl shape in the longitudinal direction. This is because the rod-shaped portion 31 is bent into a bowl shape, and compared with a straight structure, excess force can be released, and the scalp can be more comfortably stimulated. In addition, the rod-shaped portion 31 may have a second function as appropriate by being bent into a bowl shape in the longitudinal direction. This is because the rod-shaped portion 31 has a bowl-shaped raised portion, so that the hair can be more appropriately lifted from the scalp in this portion. In the scalp environment improving device according to the first embodiment, it is preferable that at least the front end portion of the rod-shaped portion 31 is located in the flow path of the charged particles in the scalp contact body 3 and is disposed on the outer periphery of the flow path. nearby. Here, the flow path of the charged particles and the periphery of the flow path will be described using FIG. 5. Fig. 5 is a schematic perspective view for explaining an outer diameter of a blow-out port. First, the outer diameter of the air outlet 12 (the area indicated by a broken line in FIG. 5) when the air outlet 12 is viewed from the outside is regarded as an exhaust surface (the area surrounded by a broken line in FIG. 5). In Fig. 5, the exhaust surface is missing a part of the circle. A portion of the cylindrical shape formed by continuously moving the exhaust surface from the outlet 12 in parallel to the outer side of the casing 1 is regarded as a flow path of charged particles. In addition, it goes without saying that in practice, the charged particles are discharged to the outside while being diffused in all directions. In addition, the vicinity of the center of the flow path means the vicinity of the center when the flow path is viewed from the direction in which the flow path extends (the direction in which the self-blowing outlet 12 extends toward the outer side of the housing 1), and the vicinity of the periphery of the flow path , Means the vicinity of the outer periphery when the flow path is visually viewed from the direction in which the flow path extends. The reason why the front end portion of the rod-shaped portion 31 is arranged closer to the outer periphery than the vicinity of the center of the flow path of the charged particles is as follows. The charged particles are sent out while being diffused outward from the blowing outlet 12. Therefore, the concentration of the charged particles near the periphery in the flow path tends to be lower than the concentration of the charged particles near the center in the flow path. Based on the premise described above, it is assumed that the front end portion of the rod-shaped portion 31 is arranged near the center in the flow path of the charged particles. In this case, when the scalp contact body 3 is brought into contact with the scalp, if the scalp contact body 3 is moved (for example, about 10 cm), the scalp exposed to the outside becomes the current contact position at the front end portion and from that position. Off the scalp between 10 cm. At this time, a deviation occurs between the position near the center where the high-concentration charged particles exist and the position of the externally exposed scalp. The reason is that the current contact position of the front end portion is near the center of the flow path. On the other hand, it is assumed that the front end portion of the rod-shaped portion 31 is arranged near the outer periphery 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 high-concentration charged particles exist and the position of the scalp exposed to the outside is smaller than in the case described above. The reason is that the current contact position of the front end portion is near the outer periphery of the flow path, and the position of the scalp exposed to the outside in the vicinity of the flow path can be near the center of the flow path. Therefore, by disposing the front end portion of the rod-shaped portion 31 closer to the outer periphery than the vicinity of the center of the flow path of the charged particles, it is possible to more effectively introduce the charged particles to the scalp exposed to the outside. (Second Embodiment) This second embodiment is different from the first embodiment in that the scalp environment improving device further includes a cover. In the present embodiment, the differences from the first embodiment will be described, and there is a case where the description will not be repeated. 6 is a perspective view showing a scalp environment improving device according to a second embodiment. As shown in FIG. 6, the scalp environment improving device further includes a cover body 4 surrounding the scalp contact body 3. The cover 4 has a function of forming a flow path for guiding the charged particles sent from the blow-out port 12 to the scalp in contact with the scalp contact body 3. Specifically, the cover 4 has a substantially cylindrical shape that is connected to the outlet-side end portion 41 of the outlet 12 and the outer-side end portion 42 facing the outlet. In particular, the area surrounded by the cover body 4 from the blow-out outlet-side end portion 41 toward the outer side end portion 42 has a greatly expanded shape. The cover 4 having such a structure can effectively guide the air containing charged particles sent from the blowing outlet 12 to the outside to the rod-shaped portion 31 of the scalp contact body 3 without hindering the function of the scalp contact body 3. Wind road. The cover body 4 may be formed integrally with the scalp contact body 3 as shown in FIG. 6, or may be separately formed as a member different from the scalp contact body 3. If the cover 4 is not provided, the air containing the charged particles can be freely diffused between the self-blowout port 12 and the scalp. Therefore, the concentration of charged particles reaching the scalp (a / cm 3 ) Compared with the concentration of charged particles just sent to the outside from the blowing outlet 12 (pcs / cm 3 ) Becomes smaller. In contrast, according to the scalp environment improving device provided with the cover body 4, the air containing charged particles sent from the blowing outlet 12 is guided into the air passage formed by the cover body 4 and reaches the vicinity of the end of the air passage scalp. In this case, as compared with a case where the air containing the charged particles diffuses freely from the time when the air outlet 12 reaches the scalp, the charged particles with a higher concentration can reach the scalp. (Embodiment 3) This Embodiment 3 is a scalp environment improvement method using the scalp environment improvement apparatus of Embodiment 1 or 2. This scalp environment improvement method is a method of sending charged particles to the scalp in a state where the scalp contact body 3 is in contact with the scalp. FIG. 7 is a schematic diagram showing a state in which the scalp environment improvement method according to the third embodiment is implemented. FIG. 8 is a schematic diagram showing a state near the scalp in the scalp environment improving method according to the third embodiment. In this embodiment, a scalp environment improving device is used as shown in FIG. 7. 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 a comfortable stimulus to the scalp and removing the hair on the scalp and floating it from the scalp, so that the scalp under the hair and the self-blowing outlet 12 The second function is that the delivered charged particles are easy to contact. Thereby, while the scalp can be properly stimulated, the charged particles can effectively reach the scalp, so the improvement of the scalp environment described above becomes possible. The above method is to move the front end portion on the scalp in a state where the front end portion of the rod-shaped portion 31 of the scalp contact body 3 of the scalp environment improving device is in contact with the scalp, for example. For the movement at this time, it is preferable to set the speed and intensity of the stimulus caused by sliding forward on the scalp to the front end to a degree that the user feels comfortable. With the above-mentioned movement, the hair growing on the scalp moving at the front end portion becomes a state of floating from the scalp. That is, compared with a case where the front end portion is not moved, the hair on the scalp in a larger area becomes a state floating from the scalp. Thereby, it is possible to expand a region in the scalp where the charged particles efficiently reach. Moreover, by using this movement, a more comfortable stimulation can be given to the scalp. [Examples] The present invention will be described more specifically below with reference to examples and comparative examples, but the present invention is not limited in any way. (Study 1) Six women between the ages of 40 and 65 were taken as subjects, and every three people were randomly assigned to test area 1 and test area 2 to perform a double-blind crossover test. Machine A and Machine B were used in the test. The machine A is an example machine, which is equivalent to the scalp environment improving device of the first embodiment. Device B is a control device for a comparative example, and is equivalent to a device obtained by removing the charged particle generating unit 13 from the scalp environment improving device according to the first embodiment. [Experiment] A third person (inspection staff) different from the subject is subjected to the first treatment on the right scalp of the subject in the test area 1. Specifically, the right side scalp of the subject in the test area 1 was performed 60 times or less, that is, in a state where the front end portion of the rod-shaped portion provided in the machine A was in contact with the scalp, the front end portion was moved from the head After moving the front toward the back of the head for 3 seconds, move the front part away from the scalp for 2 seconds. As a result, the entire right scalp of the subject in the test area 1 was subjected to stimulus caused by the rod-shaped portion and warm air blowing including charged particles for 5 minutes. After the above operation is completed, a time interval of 60 minutes for keeping the subject in a quiet state is performed. After the end of the time interval, a second treatment was performed on the left scalp of the subject. The second treatment on the left scalp is set to be the same as the first treatment on the right scalp, except that the device B is used instead of the device A. As a result, the entire left scalp of the subject in the test area 1 was subjected to stimulus and warm air (excluding charged particles) from the rod-shaped portion for 5 minutes. Table 1 shows the setting conditions when using machine A and machine B. In addition, the temperature in Table 1 is measured by a thermometer arranged at a position 15 cm away from the self-blowing outlet. [Table 1] As can be seen from the above, among the subjects in the test area 1, the first treatment using the machine A was performed on the entire right scalp, and the second treatment using the machine B was performed on the entire left scalp. On the other hand, for each subject in test area 2, the same test as above was performed except that machine B was used for the first treatment on the right scalp and machine A was used for the second treatment on the left scalp. test. That is, the test of the right scalp of the subject in the test area 1 and the left scalp of the subject in the test area 2 is an example. The scalp test is a comparative example. [Evaluation] The following conditions were evaluated for subjects in test area 1 and subjects in test area 2, namely: (a) the scalp environment status of the right scalp immediately before the first treatment; (b) the first treatment was just performed The scalp environmental state of the right scalp on the right; (c) the scalp environmental state of the left scalp immediately before the second treatment; and (d) the scalp environmental state of the left scalp immediately after the second treatment. The average of the values of (a) of the subject in test area 1 and (c) of the subject in test area 2 is set to the value of the example (before treatment), and The average value of (b) and (d) of the subject in the test area 2 is set to the value of the example (after treatment). In addition, the average value of each value of (c) of the test subject in test area 1 and (a) of the test subject in test area 2 was set to the value of the comparative example (before processing), and the test value in test area 1 was tested. The average of the values of (d) of the subject and (b) of the subject to be tested in the test area 2 is set to the value of the comparative example (after treatment). The values in the examples and comparative examples are average values. The evaluation items of the examples (before processing), the examples (after processing), the comparative examples (before processing), and the comparative examples (after processing) are listed in the following [1] to [4]. [1] The scalp moisture content is measured using a transdermal moisture evapotranspiration measuring device ("Tewameter TM 300", manufactured by Courage + Khazaka electronic) (g / (m 2 ・ Hr)). The results of each subject were averaged and used as the evaluation results. [2] The oil content of the scalp was measured using an oil content meter ("Sebumeter SM815", manufactured by Courage + Khazaka electronic) to measure sebum secretion (μg / cm) 2 ). The results of each subject were averaged and used as the evaluation results. [3] Sensory Evaluation 1: Softness of Scalp About 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 indicated on the evaluation stick indicating only the lower limit and the upper limit, at the position where each subject considered that the scalp was soft. Secondly, different from the result of the third person for each subject, the lower and upper limits of the evaluation stick are set to "0" and "100", the positions of each mark are digitized, and the processing is calculated. The average of the previous value and the average of the processed value. [4] Sensory evaluation 2: scalp warmth About the scalp warmth, the sensory evaluation of each experimenter 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 marked the position corresponding to the "feel that the scalp is gradually warming" on the evaluation stick indicating only the lower limit and the upper limit. Secondly, different from the result of the third person for each subject, the lower and upper limits of the evaluation stick are set to "0" and "100", the positions of each mark are digitized, and the processing is calculated. The average of the previous value and the average of the processed value. Next, a value obtained by subtracting the obtained value (average value) from the obtained processed value (average value) is calculated. [Evaluation Results] The evaluation results of the above [1] to [4] are shown in Figs. 9 to 12. The error bars shown on the bars of Figures 9 to 12 represent standard errors. FIG. 9 is a graph showing the evaluation results of the moisture content of the scalp in Study 1. FIG. In the comparative example, the reduction degree of the water evapotranspiration was low by the treatment, and there was no significant difference before and after the treatment. On the other hand, in the examples, the degree of reduction in moisture evapotranspiration was large by the treatment, and it was confirmed that there was a significant difference before and after the treatment (p <0.05). From this, it can be seen that in the examples, the amount of evapotranspiration of the scalp was smaller than that of the comparative example, and therefore the scalp was maintained in a suitable state. In addition, a Wilcoxon sign rank test is used in the calculation of the p-value. FIG. 10 is a graph showing the results of the oil content of the scalp of Study 1. FIG. 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. Furthermore, 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 an appropriate oil amount on the scalp. On the other hand, in the examples, the degree of reduction in the amount of sebum secretion was small by the treatment. The p-value of the comparison between the groups before and after the treatment of the comparative example and the difference between the before and after treatment of the example is p <0.05. From this, it can be seen that, in the examples, the scalp oil content was higher than that in the comparative example, so the scalp was maintained in a suitable state. In addition, a Wilcoxon sign rank test is used in the calculation of the p-value. FIG. 11 is a graph showing the results of sensory evaluation 1 of study 1. FIG. In the comparative example, the evaluation before and after the treatment did not change. On the other hand, in the examples, the evaluation of the degree of "feeling the scalp to be soft" after the treatment was higher than that before the treatment, and it was confirmed that there was a significant difference before and after the treatment (p <0.05). From this, it can be seen that, in the examples, the scalp was 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. FIG. 12 is a graph showing the results of sensory evaluation 2 of study 1. FIG. The difference before and after the treatment in the example is larger than the difference before and after the treatment in the comparative example. In addition, the p-value of the group-to-group comparison of the difference before and after the treatment of the comparative example and the difference before and after the treatment of the example is p <0.2. From this, it can be seen that, in the examples, the scalp was warmed more strongly by the treatment than in the comparative example, so that the scalp was maintained in a suitable state. In addition, a corresponding t-test is used in the calculation of the p-value. (Study 2) A group of 59 women aged 40 to 65 was selected as subjects, randomly assigned 29 to group A, and randomly selected 30 to group B, and implemented a double-blind parallel group Comparison test. In the implementation of the test, the same machine A and machine B as in Study 1 were used. Machine A is used for group A and machine B is used for group B. [Test] Subjects in group A washed and dried their hair at home, and then performed the first treatment using machine A. Specifically, the subject himself performed the following 60 or less operations on the top of his head after shampooing and drying it, that is, in a state where the front end portion of the rod-shaped portion provided in the machine A was in contact with the scalp, After moving the front part from the front of the head to the back of the head for 3 seconds, the front part is moved from the scalp for 2 seconds. As a result, the scalp on the top of the subject's head in group A was subjected to stimulus caused by the rod-shaped portion and warm air blowing including charged particles for 5 minutes. The subjects in group A performed the above test every day for 12 weeks. The subjects in group B used machine B instead of machine A, and the same tests as those in group A were performed every day for 12 weeks. [Evaluation] The evaluation items of Study 2 are listed in the following [5] to [15]. [5] to [7] are those immediately before the start of the test (week 0), 4 weeks after the test start date, 8 weeks after the test, and 12 weeks after the test. Evaluation. [8] to [15] were performed immediately before the start of the test (week 0), after 4 weeks from the start date of the test, after 8 weeks, and after 12 weeks. Person evaluation. [5] Moisture content of scalp Using the same method as in [1] above, the amount of evapotranspiration (g / (m 2 ・ Hr)). [6] Oil content of scalp Using the same method as in [2] above, the sebum secretion amount (μg / cm) of the scalp of each subject in each group was measured. 2 ). [7] The number of Malassezia bacteria on the scalp was rubbed with machine A using a sterile cotton swab ("Cotton swab for hospital use (0-319-32)", manufactured by AS ONE Co., Ltd.) in which cotton balls were dipped in physiological saline Or the scalp of the area contacted by the wind sent from the machine B, the cotton swab was immersed in a solution in a seed tube ("seed tube (9-MR84)", manufactured by Rongken Chemical Co., Ltd.). The solution in the seed tube was used as a seeding bacterial solution, and the seeding bacterial solution was seeded on an agar culture medium ("CHROMager (registered trademark) Malasse / Candida medium", Kanto Chemical Co., Ltd.) and cultured. After the cultivation, the number of Malassezia on the agar culture medium was measured, and the number of Malassezia of each subject in each group was evaluated. The measurement of the malassezia count was performed by LSI Medience Co., Ltd. [8] Sensory evaluation 3: Hair volume The hair volume of each subject was subjected to a sensory evaluation and averaged as the evaluation result. The evaluation criteria at this time are as follows. Each subject indicated on the evaluation stick that only has a lower limit and an upper limit, and marked at a position where each subject considered the degree of "feeling the increase in hair volume" equivalent. Next, the inspection staff set the values of the lower and upper limits of the evaluation stick to "0" and "100" for the results of each subject, digitized the positions of each mark, and calculated each of the A and B groups. 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. The evaluation method at this time was set to the same method as in [8] above except that the index of the evaluation stick was changed to the degree of "mind the 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. The evaluation method at this time was set to the same method as in the above [8] except that the index of the evaluation stick was changed to the degree of "mind dandruff". [11] Sensory Evaluation 6: Scalp Itching Regarding the degree of scalp itching, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. The evaluation method at this time was set to the same method as in [8] above except that the index of the evaluation stick was changed to the degree of "mind itching of the scalp". [12] Sensory evaluation 7: Degree of white hair About the degree of white hair, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. The evaluation method at this time was set to the same method as in [8] above except that the index of the evaluation stick was changed to the degree of "mind the white hair". [13] Sensory evaluation 8: The degree of odor of the scalp with respect to the odor of the scalp, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. The evaluation method at this time was set to the same method as in [8] above except that the index of the evaluation stick was changed to the degree of "mind the odor of the scalp". [14] Sensory evaluation 9: The degree of the seam of the hair with respect to the seam of the hair, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. The evaluation method at this time was set to the same method as in [8] above except that the index of the evaluation stick was changed to the degree of "mind the seam of hair". [15] Sensory evaluation 10: Heavyness of the head Regarding the degree of heavyness of the head, the sensory evaluation of each subject was performed, and the average was used as the evaluation result. The evaluation method at this time was set to the same method as the above [8] except that the index of the evaluation stick was changed to a degree of "heavy head felt 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, and 23 mean standard error. FIG. 13 is a graph showing the evaluation results of the evapotranspiration of the scalp in Study 2. FIG. The blank stick (Example) is the change amount of the water evapotranspiration of the subject's scalp in group A, and it is the average of the values of each subject from the value of week 12 minus the value of week 0 value. The bar (comparative example) indicated by oblique shading is the change amount of the evapotranspiration of the subject's scalp in group B, and it is the value of each subject from the value of week 12 minus the value of week 0 The average. In group A, the amount of change in water evapotranspiration was negative. That is, in the embodiment, the evapotranspiration of the scalp at the 12th week is smaller than that of the scalp at the 0th week. On the other hand, in the B group, the change amount of the water evapotranspiration amount was a positive value. That is, in the comparative example, the amount of evapotranspiration of the scalp at the 12th week was larger than that of the scalp at the 0th week. Furthermore, a significant difference was confirmed between Examples and Comparative Examples (p <0.05). From this, it can be seen that the evapotranspiration of the scalp was smaller in the examples than in the comparative examples, and therefore the scalp was maintained in a suitable state. In addition, in the calculation of the p-value, a Mann-Whitney U test was used. FIG. 14 is a graph showing the evaluation results of the oil content of the scalp in Study 2. FIG. The blank stick (example) is the amount of change in the oil content of the subject's scalp in group A, and is the average of the values of each subject from the value of week 8 minus the value of week 0. The bar (comparative example) indicated by oblique shading is the amount of change in the oil content of the subject's scalp in group B, and is the average of the values of each subject from the value of week 8 minus the value of week 0 . The changes in the oil content of Group A and Group B were negative, and their absolute values were larger for Group A. That is, the oil content of the scalp of the 8th week compared with the comparative example in Example was significantly reduced compared with the oil content of the scalp of the 0th week. Furthermore, a significant difference was confirmed between Examples and Comparative Examples (p <0.05). From this, it can be seen that the degree of reduction in the amount of oil in the scalp was greater in the examples than in the comparative examples, and therefore the scalp was maintained in a suitable state. In addition, in the calculation of the p-value, a Mann-Whitney U test was used. FIG. 15 is a graph showing the evaluation results of the Malassezia count of Study 2. FIG. The broken line (example) shown by the solid line is the change of the number of Malassezia from the scalp of the subject in group A from the 0th week, and the 0th, 4th, and 8th weeks of the start of the test Each Malassezia number is the average of the changes from the 0th week. The broken line (comparative example) shown by the dotted line is the transition of the number of Malassezia from the scalp of the subject in group B from the 0th week, and the 0th, 4th, and 8th weeks of the start of the test The average value of the amount of change of each Malassezia number from the 0th week is consecutive. The number of Malassezia in group A decreased significantly after 8 weeks (about 64% reduction). In contrast, the number of Malassezia bacteria in group B has not seen a significant decrease after 8 weeks from the start of the test. From this, it can be seen that the degree of reduction of the number of malassezia in the scalp was larger in the examples than in the comparative examples, and therefore the scalp was maintained in a suitable state. FIG. 16 is a graph showing evaluation results of sensory evaluation 3 of study 2. FIG. The blank stick (example) is the result (average value) of the sensory evaluation of the subject in group A, and shows the result of the 0th week and the result of the 12th week. The bar (comparative example) indicated by oblique shading is the result (mean) of the sensory evaluation of the subject's scalp in group B, and the results at the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "feeling an increase in hair volume" was greater in the 12th week than in the 0th week, and in particular, the degree of the change was greater in the examples. Furthermore, the p-value of the comparison between the examples and comparative examples at the 12th week was p <0.1. From this, it can be seen that, in the examples, the hair volume tends to be strongly felt compared with the comparative example, and therefore the scalp tends to be maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used. FIG. 17 is a graph showing evaluation results of sensory evaluation 4 of study 2. FIG. The blank stick (example) is the result of the sensory evaluation of the subject in group A, and is the value of the value of the evaluation result of the test subject minus the value of the evaluation result of the 0th week for each subject. The average. The bar (comparative example) indicated by the oblique hatching is the result of the sensory evaluation of the subjects in group B, and is the value of each subject from the evaluation result of the 12th week minus the evaluation result of the 0th week The average of the values. The average value of the degree of change in sensory evaluation (change in VAS value) in group A was about -15.0, while the average value of change in VAS value in group B was about -7.0. Furthermore, the p-value of the comparison between the examples and comparative examples was p <0.2. From this, it can be seen that in the examples, compared with the comparative examples, there is a tendency that the degree of reduction in the degree of hair loss is strongly felt, and therefore the scalp tends to be maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used. In addition, the VAS system means Visual Analogue Scale. FIG. 18 is a graph showing evaluation results of sensory evaluation 5 of study 2. FIG. The blank stick (example) is the result (average value) of the sensory evaluation of the subject in group A, and shows the result of the 0th week and the result of the 12th week. The bar (comparative example) indicated by oblique shading is the result (mean) of the sensory evaluation of the subject's scalp in group B, and the results at the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "mind dandruff" was smaller in the 12th week than in the 0th week, and in particular, the degree of change in the examples was larger. Furthermore, the p-value of the comparison between the Examples and Comparative Examples at Week 12 was p <0.2. From this, it can be seen that, in the examples, compared with the comparative example, there is a tendency that the degree of reduction of the dandruff is strongly felt, and therefore the scalp tends to be maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used. FIG. 19 is a graph showing evaluation results of sensory evaluation 6 of study 2. FIG. The blank stick (example) is the result (average value) of the sensory evaluation of the subject in group A, and shows the result of the 0th week and the result of the 12th week. The bar (comparative example) indicated by oblique shading is the result (mean) of the sensory evaluation of the subject's scalp in group B, and the results at the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "mind itching of the scalp" was smaller in the 12th week than in the 0th week, and in particular, the degree of change in the examples was larger. Furthermore, the p-value of the comparison between the examples and comparative examples at week 12 was p <0.05, and a significant difference was confirmed. From this, it can be seen that, in the examples, compared with the comparative example, it was strongly felt that the itchiness of the scalp was reduced, so the scalp was maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used. FIG. 20 is a graph showing evaluation results of sensory evaluation 7 of study 2. FIG. The blank stick (example) is the result (average value) of the sensory evaluation of the subject in group A, and shows the result of the 0th week and the result of the 12th week. The bar (comparative example) indicated by oblique shading is the result (mean) of the sensory evaluation of the subject's scalp in group B, and the results at the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "mind the gray hair" is smaller in the 12th week than in the 0th week, and the degree of the change in the example is greater in particular. Furthermore, the p-value of the comparison between the examples and comparative examples at the 12th week was p <0.1. From this, it can be seen that, in the examples, compared with the comparative example, there is a tendency that the degree of reduction of the degree of minding of white hair is strongly felt, and therefore the scalp tends to be maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used. FIG. 21 is a graph showing evaluation results of sensory evaluation 8 of study 2. FIG. The blank stick (example) is the result (average value) of the sensory evaluation of the subject in group A, and shows the result of the 0th week and the result of the 12th week. The bar (comparative example) indicated by oblique shading is the result (mean) of the sensory evaluation of the subject's scalp in group B, and the results at the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "mind the odor of the scalp" was smaller in the 12th week than in the 0th week, and in particular, the degree of change in the degree was larger in the examples. Furthermore, the p-value of the comparison between the examples and comparative examples at the 12th week was p <0.1. From this, it can be seen that, in the examples, compared with the comparative example, there is a tendency that the odor of the scalp is strongly felt to be reduced, and therefore the scalp is tended to be maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used. 22 is a graph showing evaluation results of sensory evaluation 9 of study 2. The blank stick (example) is the result (average value) of the sensory evaluation of the subject in group A, and shows the result of the 0th week and the result of the 12th week. The bar (comparative example) indicated by oblique shading is the result (mean) of the sensory evaluation of the subject's scalp in group B, and the results at the 0th week and the 12th week are shown. In either of the examples and the comparative examples, the degree of "mind the slitting" in the 12th week is smaller than that in the 0th week, and in particular, the degree of variation in the degree is larger in the examples. Furthermore, the p-value of the comparison between the examples and comparative examples at the 12th week was p <0.1. From this, it can be seen that, in the examples, compared with the comparative example, there is a tendency that the degree of mindfulness of the seam reduction is strongly felt, so the scalp tends to be maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used. FIG. 23 is a graph showing evaluation results of sensory evaluation 10 of Study 2. FIG. The blank stick (example) is the result of the sensory evaluation of the subject in group A, and is the value of the value of the evaluation result of the test subject minus the value of the evaluation result of the 0th week for each subject. The average. The bar (comparative example) indicated by the oblique hatching is the result of the sensory evaluation of the subjects in group B, and is the value of each subject from the evaluation result of the 12th week minus the evaluation result of the 0th week The average of the values. The average value of the degree of change in sensory evaluation (change in VAS value) in group A was about -17.5, while the average value of change in VAS value in group B was about -8.0. Furthermore, the p-value of the comparison between the examples and 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 lighter, and the scalp tends to be maintained in an appropriate state. In addition, in the calculation of the p-value, a t-test without correspondence is used.
