従来より、毛髪の傷み具合等について、目視により診断することが行われている。
これに対して、例えば、特許文献１では、毛髪の傷み具合をより適切に診断することを目的として、被験者の毛髪における複数の部位の拡大画像を同時に診断画面上で表示させることで、毛髪の正常な部位と傷んだ部位等を見比べながら診断を行うことを提案している。
Conventionally, visual diagnosis of hair damage and the like has been performed.
On the other hand, for example, in Patent Document 1, for the purpose of more appropriately diagnosing the degree of hair damage, an enlarged image of a plurality of sites in the subject's hair is displayed on the diagnosis screen at the same time, thereby It is proposed to make a diagnosis by comparing normal and damaged sites.
ところで、特許文献１に記載の診断方法等の従来の毛髪に関する診断では、毛髪自体の状態を目視により確認すること又は毛髪自体の画像を見比べることにより行われているものばかりであり、毛髪自体の状態を確認する診断方法以外の診断方法は提案されておらず、これまで検討もなされていない。 By the way, in the conventional diagnosis relating to hair such as the diagnostic method described in Patent Document 1, it is only performed by confirming the state of the hair itself by visual observation or comparing images of the hair itself. No diagnostic method other than the diagnostic method for confirming the state has been proposed and has not been studied so far.
本発明は、上記事情に鑑み、毛髪に関するこれまでに無い新しい評価方法、毛髪処理剤の選定方法、及び評価支援ツールの提供を目的とする。 In view of the above circumstances, an object of the present invention is to provide an unprecedented new evaluation method for hair, a method for selecting a hair treatment agent, and an evaluation support tool.
本発明者等が、これまで着目されていなかった観点である頭皮の赤みが毛髪にいかなる影響を及ぼすのかという観点から鋭意検討を行った結果、被評価者の頭皮の赤みに応じて、被評価者の白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率が異なることを新たに見出し、被評価者の頭皮の赤みに着目すれば、被評価者の白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率を診断することが可能になることをさらに見出すことで、本発明を完成するに至った。 As a result of intensive studies from the viewpoint of how the redness of the scalp, which has not been noticed so far, has an effect on the hair, the present inventors have evaluated it according to the redness of the scalp of the evaluated person. Newly found that the number of white hair, the number of hairs, the variation in hair thickness, and the thinning rate differ, and focusing on the redness of the scalp of the evaluator, The present invention has been completed by further finding out that it is possible to diagnose a large number, a small number of hairs, a large variation in hair thickness, and a fine hair rate.
すなわち、本願発明の評価方法では、白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかを被評価者の頭皮の赤み又は赤みに関する指標に応じて評価する。 That is, in the evaluation method of the present invention, at least one of the amount of gray hair, the number of hairs, the variation in hair thickness, and the fine hair rate is determined according to an index related to redness or redness of the scalp of the subject. evaluate.
なお、上記評価方法では、被評価者の年齢に応じた頭皮の赤み又は赤みに関する指標の比較基準となる情報を用いて評価を行うことが好ましい。
頭皮に赤みを有する者の割合や赤みの程度は年齢に応じて変化するものの、当該評価方法によれば、被評価者の頭皮の状態の同年代中での位置づけを客観的に把握することが可能になる。また、年代別の複数の情報を用いた評価を行うことで、被評価者が現状の頭皮の赤み等の程度のままで年齢を重ねた場合、及び、被評価者が現状の頭皮の赤み等の程度が加齢に応じて変化した場合における、将来の白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかを予測することが可能となる。
In the above evaluation method, it is preferable that the evaluation is performed using redness of the scalp according to the age of the person to be evaluated or information that serves as a reference for comparing indices relating to redness.
Although the percentage of people with redness on the scalp and the degree of redness vary with age, the assessment method can objectively grasp the status of the scalp in the same age group. become. In addition, by performing evaluation using multiple information by age group, when the person to be evaluated grows age with the degree of redness of the current scalp, etc., and when the person to be evaluated has redness of the current scalp, etc. It is possible to predict at least any one of the future number of gray hairs, the number of hairs, the variation in hair thickness, and the fineness rate when the degree of hair changes according to aging.
また、本願発明の毛髪処理剤の選定方法では、上記評価方法により得られる評価結果に応じて被評価者に対して推奨する毛髪処理剤の選定を行う。 Moreover, in the selection method of the hair treatment agent of this invention, the hair treatment agent recommended with respect to a to-be-evaluated person is selected according to the evaluation result obtained by the said evaluation method.

Information serving as a reference for comparison with the redness of the person's scalp or an index relating to redness is displayed.
本発明に係る評価方法、毛髪処理剤の選定方法、及び評価支援ツールによれば、白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかに関し、これまでに無い新しい評価を行うことが可能となる。 According to the evaluation method, the method for selecting a hair treatment agent, and the evaluation support tool according to the present invention, at least one of the amount of white hair, the number of hairs, the variation in hair thickness, and the fine hair rate, It is possible to perform a new evaluation that has never been done before.
以下、本発明の実施形態に係る評価方法、毛髪処理剤の選定方法、及び評価支援ツールを例に挙げつつ説明するが、これらは特に発明を限定するものではない。 Hereinafter, the evaluation method, the hair treatment agent selection method, and the evaluation support tool according to the embodiment of the present invention will be described as examples, but these do not particularly limit the invention.
（評価方法）
本実施形態の評価方法は、白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかを被評価者の頭皮の赤み又は赤みに関する指標（以下、「赤み又は赤みに関する指標」を「赤み等」と称する場合がある。）に応じて評価する。
(Evaluation method)
The evaluation method of the present embodiment uses at least one of a large amount of white hair, a small number of hairs, a variation in hair thickness, and a thinning rate as an index (hereinafter referred to as “redness or redness of the scalp of the evaluation subject). "Redness or an index relating to redness" is sometimes referred to as "redness etc.").
赤みとは、特に限定されず、肉眼による観察又はマイクロスコープ等の画像取得手段を用いた観察により赤いと感じる度合いであってもよく、特に、評価結果の客観性を高める観点から、マイクロスコープ等の画像取得手段により得られる頭皮の画像から把握されるＬ＊ａ＊ｂ＊表色系における色度ａ＊値の高さとすることが好ましい。例えば、被評価者の頭皮のａ＊値が、所定の基準となる者の頭皮のａ＊値よりも高い場合には、被評価者の頭皮が、所定の基準となる者の頭皮よりも赤みが強いということになる。 Redness is not particularly limited, and may be a degree of redness by observation with the naked eye or observation using an image acquisition means such as a microscope. In particular, from the viewpoint of enhancing the objectivity of the evaluation result, a microscope, etc. Preferably, the height of the chromaticity a * value in the L * a * b * color system is grasped from the scalp image obtained by the image acquisition means. For example, when the a * value of the scalp of the person being evaluated is higher than the a * value of the scalp of the person serving as the predetermined reference, the scalp of the person being evaluated is redder than the scalp of the person serving as the predetermined reference Is strong.
赤みに関する指標としては、特に限定されず、肉眼による観察又はマイクロスコープ等の画像取得手段を用いた観察により、赤に対して略補色の関係にある青、緑、青緑等の色味を感じる度合いであってもよく、評価結果の客観性を高める観点から、マイクロスコープ等の画像取得手段により得られる頭皮の画像から把握されるＬ＊ａ＊ｂ＊表色系における色度ａ＊値の低さとすることが好ましい。例えば、被評価者の頭皮のａ＊値が、所定の基準となる者の頭皮のａ＊値よりも低い場合には、被評価者の頭皮が、所定の基準となる者の頭皮よりも赤みが弱いということになる。 The index for redness is not particularly limited, and the color of blue, green, blue-green, etc., which are substantially complementary to red, is felt by observation with the naked eye or by using image acquisition means such as a microscope. The degree of the chromaticity a * value in the L * a * b * color system captured from the scalp image obtained by an image acquisition means such as a microscope from the viewpoint of enhancing the objectivity of the evaluation result It is preferable to make it low. For example, if the a * value of the scalp of the person being evaluated is lower than the a * value of the scalp of the person serving as the predetermined reference, the scalp of the person being evaluated is redder than the scalp of the person serving as the predetermined reference Is weak.
頭皮の赤み等の評価対象部位としては、例えば、トップ（頭の頂上部）、フロント（前頭部）、サイド（耳の上）、バック（後頭部）、ネープ（後頭部の下部・えりあし）の各部を用いることができるが、目視やマイクロスコープで観察しやすい部位であるトップ（頭の頂上部）及び／又はフロント（前頭部）を評価対象部位とすることが好ましい。なお、頭皮の日焼けが評価に与える影響を小さく抑えるために、分け目やつむじ周囲を除く部位を評価対象部位とすることが好ましい。また、評価の客観性を高める観点から、比較の際には同じ評価対象部位同士を比較することが好ましい。 Examples of scalp redness evaluation sites include the top (top of the head), front (frontal head), side (above the ears), back (back of the head), and nape (lower back of the head, area) Although each part can be used, it is preferable to set the top (top of the head) and / or the front (frontal head), which are parts that can be easily observed visually or with a microscope, as the evaluation target part. In addition, in order to suppress the influence which the sunburn of a scalp has on evaluation, it is preferable to make into the evaluation object site | parts the part except a division and the circumference of a toothpick. In addition, from the viewpoint of improving the objectivity of evaluation, it is preferable to compare the same evaluation target parts in the comparison.
白髪の多さを評価する場合には、被評価者の頭皮の赤みが強いほど白髪が多く、被評価者の頭皮の赤みが弱いほど白髪が少ない傾向があると評価する。ここで、白髪の多さの評価では、例えば、頭皮の評価対象部位における所定の単位面積当たりに生える毛髪の合計本数中の白髪の本数の割合（白髪率）を用いることができる。所定の単位面積としては、特に限定されず、例えば、マイクロスコープ等の画像取得手段を所定の倍率で用いた場合に画面に映し出される範囲としてもよい（以下、同じ）。 When evaluating the amount of gray hair, it is evaluated that the greater the redness of the scalp of the evaluated person, the more white hair, and the weaker the scalp of the evaluated person, the less white hair tends to be. Here, in the evaluation of the amount of gray hair, for example, the ratio of the number of gray hairs (white hair rate) in the total number of hairs grown per predetermined unit area in the scalp evaluation target site can be used. The predetermined unit area is not particularly limited, and may be a range displayed on the screen when image acquisition means such as a microscope is used at a predetermined magnification (hereinafter the same).
毛髪本数の少なさを評価する場合には、被評価者の頭皮の赤みが強いほど毛髪本数が少なく、被評価者の頭皮の赤みが弱いほど毛髪本数が多い傾向があると評価する。ここで、毛髪本数の少なさの評価では、頭皮の評価対象部位における所定の単位面積当たりに生える毛髪の合計本数を用いてもよいし、マイクロスコープ等の画像取得手段で取得される画像に白黒二値化処理を施した場合の黒い部分の割合を用いてもよい。 When evaluating the small number of hairs, it is evaluated that the stronger the redness of the scalp of the person to be evaluated, the smaller the number of hairs, and the weaker the redness of the scalp of the person to be evaluated, the greater the number of hairs. Here, in the evaluation of the small number of hairs, the total number of hairs grown per predetermined unit area in the scalp evaluation target site may be used, or the image acquired by image acquisition means such as a microscope may be black and white. You may use the ratio of the black part at the time of performing a binarization process.
毛髪太さのばらつきの大きさを評価する場合には、被評価者の頭皮の赤みが強いほど毛髪太さのばらつきが大きく、被評価者の頭皮の赤みが弱いほど毛髪太さのばらつきが小さい傾向があると評価する。ここで、毛髪太さのばらつきの大きさの評価では、例えば、頭皮の評価対象部位における所定の単位面積当たりに生える毛髪についての毛径の標準偏差を用いることができる。 When evaluating the variation in hair thickness, the greater the redness of the scalp of the evaluator, the greater the variation in hair thickness, and the weaker the redness of the scalp of the evaluator, the smaller the variation in hair thickness. Assess that there is a tendency. Here, in the evaluation of the size of the variation in hair thickness, for example, the standard deviation of the hair diameter of the hair grown per predetermined unit area in the scalp evaluation target site can be used.
細毛率を評価する場合には、被評価者の頭皮の赤みが強いほど細毛率が高く、被評価者の頭皮の赤みが弱いほど細毛率が低い傾向があると評価する。ここで、細毛率の評価では、頭皮の評価対象部位における所定の単位面積当たりに生える毛髪の合計本数中の毛径が４０μｍ以下である細毛の本数の割合（細毛率）を用いることができる。 When the fine hair rate is evaluated, it is evaluated that the higher the redness of the scalp of the person to be evaluated, the higher the fine hair rate, and the lower the redness of the scalp of the person to be evaluated, the lower the fine hair rate. Here, in the evaluation of the fine hair rate, the ratio (the fine hair rate) of the number of fine hairs having a hair diameter of 40 μm or less in the total number of hairs grown per predetermined unit area in the scalp evaluation target site can be used.
上記評価を行う場合には、現在の客観的な状態を把握するという観点から、被評価者の年齢に応じた頭皮の赤み等の比較基準となる情報を用いることが好ましい。 In the case of performing the evaluation, it is preferable to use information serving as a comparison criterion such as redness of the scalp according to the age of the evaluated person from the viewpoint of grasping the current objective state.
例えば、１０歳毎や５歳毎等の所定の年代毎に分けられた複数人の頭皮の赤み等に関する情報（赤み等を数値化したデータや頭皮の画像データ等）を予め用意しておき、被評価者の年齢が属する年代の頭皮の赤み等に関する情報を比較基準として用いて、被評価者の頭皮の赤み等と比較することで評価を行うことが好ましい。
頭皮に赤みを有する者の割合や赤みの程度は年代に応じて変化するものの、同年代の者の情報と比較することで、被評価者の頭皮の状態の同年代中での位置づけを客観的に把握することが可能になる。また、例えば、年代別に赤み等の程度に応じて分けた複数の段階（例えば、３段階や５段階）を予め調べて用意しておき、被評価者の頭皮の赤み等が該当する段階を特定することにより評価を行うようにしてもよいし、年代別に赤み等の程度に関する偏差値を予め調べて用意しておき、被評価者の頭皮の赤み等が該当する偏差値を特定することにより評価を行うようにしてもよい。
For example, information on the redness of the scalp of a plurality of people divided every predetermined age such as every 10 years or every 5 years (data that digitizes redness, image data of the scalp, etc.) is prepared in advance. It is preferable that the evaluation is performed by using information on the redness of the scalp in the age to which the age of the person to be evaluated belongs as a reference for comparison with the redness of the scalp of the person to be evaluated.
Although the proportion of redness on the scalp and the degree of redness vary with age, the position of the scalp of the person being evaluated in the same age can be objectively grasped by comparing it with information from those of the same age It becomes possible to do. In addition, for example, a plurality of stages (for example, 3 stages or 5 stages) divided according to the degree of redness according to age are prepared in advance, and the stage corresponding to the redness of the scalp of the evaluated person is specified. You may make it evaluate by doing, and it examines and prepares beforehand the deviation value about the degree of redness etc. according to the age, and it evaluates by specifying the deviation value to which the redness of the scalp of the person to be evaluated corresponds. May be performed.
また、複数の年代毎の頭皮の赤み等に関する情報を用いることで、被評価者が現状の頭皮の赤み等のままで年齢を重ねた場合、及び、被評価者が現状の頭皮の赤み等の程度が加齢に応じて変化した場合における、白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかのリスクを予測することが可能となる。
すなわち、被評価者の頭皮の赤み等の程度が同年代において高いと評価される場合（例えば、赤みの上位３０％）には、当該被評価者が現状の頭皮の赤みのままで年齢を重ねてしまうと、次年代以降の頭皮の赤みの程度が高い者（例えば、同じ上位３０％）における白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかと同じ状態になるリスクがあることを予測することができる。
また、被評価者の頭皮の赤みの程度が同年代において低いと評価される場合（例えば、赤みの下位３０％）には、当該被評価者が頭皮の赤みを現状の低いままで維持することができた場合には、年齢を重ねたとしても、次年代以降の頭皮の赤みの程度が低い者（例えば、同じ下位３０％）における白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかと同じ状態を確保できる傾向にあることを予測することができる。
また、被評価者の頭皮の赤み等の程度が同年代において高いと評価される場合（例えば、赤みの上位３０％）には、当該被評価者が現状の頭皮の赤みを弱めて年齢を重ねると、次年代以降の頭皮の赤みの程度が低い者（例えば、同じ下位３０％）における白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかの状態に近づける予測が可能となる。
In addition, by using information about the redness of the scalp for each of multiple ages, when the evaluated person accumulates the age with the redness of the current scalp, etc. When the degree changes according to aging, it is possible to predict the risk of at least one of the number of gray hairs, the number of hairs, the variation in hair thickness, and the fine hair rate.
That is, when the degree of redness, etc. of the scalp of the evaluated person is evaluated as being high in the same age (for example, the top 30% of redness), the evaluated person keeps the redness of the current scalp and continues to age. In other words, at least one of the number of white hair, the number of hairs, the variation in hair thickness, and the fine hair rate in those with a high degree of redness of the scalp after the next generation (for example, the same top 30%). It can be predicted that there is a risk of being in the same state.
In addition, when the degree of redness of the scalp of the evaluator is evaluated to be low in the same age (for example, the lower 30% of redness), the evaluator may maintain the redness of the scalp with the current low level. If possible, even if the age is increased, the amount of white hair, the number of hairs, and the variation in hair thickness among those with low redness of the scalp after the next generation (for example, the same lower 30%) It can be predicted that the same state as at least one of the size and the fine hair rate tends to be secured.
Further, when the degree of redness of the scalp of the evaluated person is evaluated to be high in the same age (for example, the top 30% of redness), if the evaluated person weakens the redness of the current scalp and accumulates age , At least one of the states of high white hair, small number of hairs, large variation in hair thickness, and fine hair ratio in those with low redness of the scalp since the next generation (for example, the same lower 30%) It is possible to make predictions close to.
特に、白髪の多さに関し、頭皮の赤み等の程度が同年代において高いと評価される者については、４０歳を超えたころから白髪の本数が急激に増大する傾向があることから、４０歳未満の被評価者であって頭皮の赤みの程度が高い者については、現状の頭皮の赤みのままで年齢を重ねてしまうと、今後白髪の本数が急激に増大するリスクがあることを予測することができる。 Especially for those who have a high degree of gray hair, the degree of redness of the scalp is evaluated to be high in the same age period, since the number of gray hairs tends to increase sharply from the age of 40 years old, it is less than 40 years old For those who have a high degree of redness on the scalp, predict that there will be a risk that the number of gray hair will rapidly increase in the future if the age of the scalp remains red Can do.
さらに、年代別の複数の情報を用いた評価を行うことで、被評価者の現状の頭皮の赤み等に対応する赤み等を平均値とする年代を推測すること、すなわち被評価者の頭皮の肌年齢を推測することも可能となる。 Furthermore, by performing evaluation using a plurality of information by age group, it is possible to estimate the age with an average value of redness etc. corresponding to the current scalp redness of the evaluated person, that is, the scalp of the evaluated person's scalp. It is also possible to estimate the skin age.

なお、上記評価支援ツールとしての情報端末は、特に限定されないが、例えば、頭皮の画像データ等を表示するディスプレイ、各種情報演算処理を行うＣＰＵ、ＲＡＭ、被評価者の評価の際に用いる各種データやプログラム等が格納されるＲＯＭ等の記録手段、ユーザからの情報入力を受けるタッチパネル又はキーボード等の入力手段等を有し、インターネット等のネットワークを介した通信が可能となるように構成されたものを挙げることができる。ここで、被評価者の評価の際に用いる情報は、記録手段に予め格納されていてもよいし、ネットワークを介した通信を行うことで外部のサーバ等から入手して格納してもよい。この情報端末によれは、例えば、当該入力手段を介して入力される被評価者の年代等の情報を受け付けることで、ＣＰＵが対応する年代の情報を記録手段から読み出してディスプレイに表示出力させることで、被評価者の頭皮の赤み等と比較するための比較基準となる情報を把握することができる。 The information terminal as the evaluation support tool is not particularly limited. For example, a display for displaying scalp image data, a CPU for performing various information calculation processes, a RAM, and various data used for evaluation of an evaluated person. Including a recording means such as a ROM that stores information and programs, an input means such as a touch panel or a keyboard that receives information input from the user, and is configured to be able to communicate via a network such as the Internet Can be mentioned. Here, the information used for the evaluation of the person to be evaluated may be stored in advance in the recording means, or may be obtained from an external server or the like by performing communication via a network and stored. According to this information terminal, for example, by receiving information such as the age of the person to be evaluated input via the input means, the CPU reads out the corresponding age information from the recording means and causes the display to output the information. Thus, it is possible to grasp information serving as a reference for comparison with the redness of the scalp of the person to be evaluated.
なお、評価支援ツールに表示される情報であって、被評価者の頭皮の赤み等と比較するための比較基準となる情報としては、被評価者の現在の客観的な状態を把握するという観点から、被評価者の年齢に応じた頭皮の赤み等の比較基準となる情報を用いることが好ましい。
特に、被評価者の頭皮の状態の同年代中での位置づけを客観的に把握することを可能とし、被評価者が現状の頭皮の赤み等のままで年齢を重ねた場合における、白髪の多さ、毛髪本数の少なさ、毛髪太さのばらつきの大きさ、細毛率の少なくともいずれかのリスクを予測可能とする観点から、評価支援ツールには、複数の年代毎で且つ頭皮の赤み等の程度毎に、赤み等を数値化したデータ又は頭皮の画像データ等が表示されることが好ましく、表示の仕方としては一覧表での表示であることが好ましい。
The information displayed on the evaluation support tool and used as a reference for comparison with the redness of the scalp of the person being evaluated includes the viewpoint of grasping the current objective state of the person being evaluated. Therefore, it is preferable to use information serving as a reference for comparison such as redness of the scalp according to the age of the person being evaluated.
In particular, it is possible to objectively grasp the status of the scalp of the person being evaluated in the same age, and the amount of gray hair when the person undergoes age with the redness of the current scalp remains. From the viewpoint of predicting at least one of the risks of small number of hairs, large variation in hair thickness, and fine hair rate, the evaluation support tools include the degree of redness of the scalp etc. It is preferable to display data obtained by digitizing redness or the like, or scalp image data, etc., and the display method is preferably a list display.
このような評価支援ツールにおける一覧表での表示は、例えば、図１に示すような表示を例示することができる。 The display in the list in such an evaluation support tool can illustrate the display as shown in FIG. 1, for example.
図１に示す表は、複数の年代を含む２８１人（モンゴロイドに分類される日本人女性２８１人）を対象としてマイクロスコープにより取得した頭皮の画像データと、当該画像データから把握されるａ＊値を用い、頭皮の画像データを、年代別（１０歳毎）且つａ＊値の偏差値別に示したものである。ここで偏差値は、年代毎にそれぞれａ＊値を用いて求めたものである。例えば、４０代で偏差値４５〜５５の欄に示す頭皮の画像データは、４０代におけるａ＊値の偏差値が４５〜５５である頭皮の画像データを示していることになる。 The table shown in FIG. 1 shows scalp image data acquired by a microscope for 281 people (281 Japanese women classified as Mongoloid) including a plurality of ages, and a * value obtained from the image data. The scalp image data is shown by age (every 10 years) and by a * value deviation value. Here, the deviation value is obtained using the a * value for each age. For example, the scalp image data shown in the column of deviation values 45 to 55 in the 40's indicates scalp image data in which the deviation value of the a * value in the 40's is 45 to 55.
以上の図１を参照することで、被評価者の年代の欄（縦の欄）のうち被評価者の頭皮の画像が該当する偏差値を特定することが可能になり、被評価者の同年代における頭皮の赤みの位置づけを容易に評価することができる。さらに、ここで評価された偏差値と同じ偏差値を有するより高年代の欄を参照することで、当該被評価者の将来の頭皮の赤みの推移を予測することが可能となる。また、被評価者の頭皮の画像を、各年代の偏差値５０を含む欄（横の欄）と比較することで（各年代の平均的な頭皮の画像と比較することで）、被評価者の頭皮の肌年齢を把握することも可能になる。 By referring to FIG. 1 above, it becomes possible to specify the deviation value corresponding to the scalp image of the evaluator in the age column (vertical column) of the evaluator. The position of scalp redness in can be easily evaluated. Furthermore, by referring to the column of the older age having the same deviation value as the deviation value evaluated here, it becomes possible to predict the future redness of the scalp of the subject. In addition, by comparing the scalp image of the person to be evaluated with the column (horizontal column) containing the deviation value 50 of each age (by comparing with the average scalp image of each age) It is also possible to grasp the skin age of the scalp.
なお、上記図１の例に限らず、例えば、図２に示すように、年代別（５歳毎）に、頭皮の画像データから把握されるａ＊値の偏差値を複数のグループに段階分けすることで表示してもよい。この場合には、特に、被評価者が属する偏差値のグループについて、加齢に伴う推移（ａ＊値の推移）を容易に把握することができる。 In addition to the example in FIG. 1, for example, as shown in FIG. 2, the deviation value of the a * value obtained from the scalp image data is divided into a plurality of groups for each age group (every 5 years). May be displayed. In this case, in particular, for a group of deviation values to which the evaluated person belongs, it is possible to easily grasp the transition (a * value transition) associated with aging.
なお、図１では、複数の年代のデータを一覧表として表示したが、例えば、図３〜図７に示すように、ａ＊値が高いグループ（例えば、上位３０％等）の画像データとａ＊値が低いグループ（例えば、下位３０％等）の画像データとを並べて示したものを、年代別に用意しておき、被評価者の年代に対応させて選んで用いるようにしてもよい。なお、図３〜図７は、図１に示す表の作成に当たって収集した２８１人の年代別の頭皮の画像データから作成されたものである。 In FIG. 1, data of a plurality of ages are displayed as a list. For example, as shown in FIGS. 3 to 7, image data of a group having a high a * value (for example, the top 30%) and a * Image data of a group having a low value (for example, lower 30%, etc.) arranged side by side may be prepared for each age, and may be selected and used according to the age of the person being evaluated. 3 to 7 are created from the image data of the scalp of 281 people collected at the time of creating the table shown in FIG.
なお、上記図１に示す表の作成に当たって収集した２８１人の年代別の頭皮画像のデータに基づいて、頭皮の赤みと白髪率の年代別の関係を示すグラフを図８に、頭皮の赤みと単位面積当たりの毛髪の総本数の年代別の関係を示すグラフを図９に、頭皮の赤みと毛径の標準偏差の年代別の関係を示すグラフを図１０に、それぞれ示す。なお、図８〜図１０において、「ｒｅｄ」は頭皮のａ＊値が高いグループ（例えば、上位３０％等）を示し、「ｂｌｕｅ」は頭皮のａ＊値が低いグループ（例えば、下位３０％等）を示している。 Based on the data of the 281 scalp images collected by the generation of the table shown in FIG. 1 above, a graph showing the relationship of scalp redness and gray hair rate by age is shown in FIG. FIG. 9 shows a graph showing the relationship of the total number of hairs per unit area by age, and FIG. 10 shows a graph showing the relationship by age of the redness of the scalp and the standard deviation of the hair diameter. 8 to 10, “red” indicates a group with a high scalp a * value (for example, upper 30%), and “blue” indicates a group with a low scalp a * value (for example, lower 30%). Etc.).
図８によれば、いずれの年代においても、頭皮の赤みが強い者ほど白髪率が高く、特に、頭皮の赤みが強い者については４０歳を超えてから白髪率が急激な増大する傾向にあることが確認できる（図８における矢印参照）。
また、図９によれば、いずれの年代においても、頭皮の赤みが強い者ほど単位面積当たりの毛髪の総本数が少ない傾向にあることが確認できる（図９における矢印参照）。
さらに、図１０によれば、違いの見られない２０代を除く各年代において、頭皮の赤みが強い者ほど毛径の標準偏差が大きくなる傾向にあり、毛径にばらつきが生じやすい傾向があることが確認できる（図１０における矢印参照）。
According to FIG. 8, the gray hair rate is higher for those with strong redness of the scalp in any age, and particularly for those with strong redness of the scalp, the gray hair rate tends to increase rapidly after the age of 40 years old. This can be confirmed (see the arrow in FIG. 8).
In addition, according to FIG. 9, it can be confirmed that the person with stronger redness of the scalp tends to have a smaller total number of hairs per unit area in any age (see arrows in FIG. 9).
Furthermore, according to FIG. 10, in each age except 20s in which no difference is observed, the standard deviation of the hair diameter tends to increase as the scalp has a strong redness, and the hair diameter tends to vary. This can be confirmed (see arrow in FIG. 10).
