る。Hair is damaged by chemical and thermal stimuli such as perming the hair or using a hair dryer on the hair. In damaged hair, the cuticle that protects the hair surface peels off, exposing the internal structure of the hair. If such damaged hair is not treated inappropriately, the damaged hair will rapidly become damaged, causing hair loss, split ends, and the like.
従って、例えば美容業においては、美容の施術者が、顧
客の毛髪の損傷度を調べ、毛髪の損傷度に応じてパーマ
液、シャンプー、リンス、トリートメント剤等の選択を
したり、顧客に適切な指導を行うことが求められる。Therefore, for example, in the beauty industry, a beauty practitioner examines the degree of damage to a customer's hair, selects perm solution, shampoo, conditioner, treatment agent, etc. according to the degree of hair damage, and provides appropriate treatments for the customer. Guidance is required.
従来、例えば美容業においては、毛髪の撰傷度の測定は
、美容の施術者が、直接顧客の毛髪に触れ、施術者の手
から伝わる感覚で毛髪の損傷度を判定している。Conventionally, for example, in the beauty industry, the degree of damage to hair has been measured by a beauty practitioner directly touching a customer's hair and determining the degree of hair damage by the sensation transmitted from the practitioner's hands.
上述した従来の毛髪の損傷度の判定は、施術者の感覚に

異なり、判定基準が明確ではなく、未熟な施術者の場合
は毛髪の損傷度の判定を誤り、適切な処置を行えず、あ
るいは逆に毛髪にさらにダメージを与える誤った処置を
行う危険があるという欠点がある。The conventional judgment of the degree of hair damage mentioned above relies on the senses of the practitioner, so the judgment of the degree of hair damage differs depending on the practitioner, the criteria for judgment are not clear, and inexperienced practitioners may There is a disadvantage that there is a risk of misjudging the degree of damage to the hair and not being able to perform appropriate treatment, or conversely taking the wrong treatment that will further damage the hair.

The forward frictional force when the contactor is moved and the reverse frictional force when the contactor is moved in the opposite direction from the tip of the hair to the hair root are detected, their ratio is determined, and the hair is adjusted based on this ratio. (Assessing the degree of injury.

次に本発明による毛髪の損傷度測定方法及び装置の実施
例について図面を参照して説明する。Next, embodiments of the method and apparatus for measuring the degree of hair damage according to the present invention will be described with reference to the drawings.
第１図は、本発明による毛髪の損傷度測定方法の一実施
例を説明するための毛髪の部分断面図である。第１図に
おいて、毛髪のキューティクル４は、毛髪表面を保護し
、屋根瓦状に重なり合っている。毛髪が損傷すると、こ
のキューティクル４が、毛髪表面より剥離し、毛髪の内
部構造が露出する。この、毛髪の内部構造の露出の程度
を調べることにより、毛髪の損傷度が測定できる。FIG. 1 is a partial cross-sectional view of hair for explaining an embodiment of the method for measuring the degree of hair damage according to the present invention. In FIG. 1, hair cuticles 4 protect the hair surface and overlap like roof tiles. When hair is damaged, the cuticle 4 separates from the hair surface, exposing the internal structure of the hair. By examining the degree of exposure of the internal structure of the hair, the degree of hair damage can be measured.
接触子３を毛髪に接触させると、接触子３は、毛髪表面
を被っているキューティクル４と接触する。この状態で
、毛髪と接触子３とを毛髪の長手方向に相対的に移動さ
せるが、本実施例では、接触子３を移動させる場合につ
いて述べる。図中の矢印ａで示される方向、すなわち毛
髪の毛根から毛先へ向かう方向（順方向）に接触子３を
移動する。このとき、接触子３の接触面３′とキューテ
ィクル４により発生する摩擦力（以下、順方向摩擦力と
する）を検出する。When the contactor 3 is brought into contact with the hair, the contactor 3 comes into contact with the cuticle 4 covering the hair surface. In this state, the hair and the contact 3 are moved relative to each other in the longitudinal direction of the hair. In this embodiment, a case where the contact 3 is moved will be described. The contactor 3 is moved in the direction shown by arrow a in the figure, that is, in the direction from the hair root to the hair tip (forward direction). At this time, a frictional force (hereinafter referred to as forward frictional force) generated between the contact surface 3' of the contactor 3 and the cuticle 4 is detected.
次に図中の矢印すで示される方向、すなわち毛髪の毛先
から毛根へ向かう方向（逆方向）に、接触子３を移動す
る。このとき、接触子３の接触面３′とキューティクル
４により発生する摩擦力（以下、逆方向摩擦力とする）
を検出する。Next, the contactor 3 is moved in the direction indicated by the arrow in the figure, that is, in the direction from the tip of the hair to the root of the hair (in the opposite direction). At this time, the frictional force generated between the contact surface 3' of the contactor 3 and the cuticle 4 (hereinafter referred to as reverse frictional force)
Detect.
接触子３を、毛根から毛先へ向かう方向（順方向）に移
動するとき発生する順方向摩擦力は、小さいが、接触子
３を、毛先から毛根へ向かう方向（逆方向）に移動する
とき発生する逆方向摩擦力は、瓦状のキューティクルの
先端が引っかかり、キューティクル４による抵抗が大き
くなるので、大きくなる。Although the forward frictional force generated when the contact 3 is moved in the direction from the hair root to the hair tip (forward direction) is small, the contact 3 is moved in the direction from the hair tip to the hair root (reverse direction). The reverse frictional force generated at this time increases because the tip of the tile-shaped cuticle gets caught and the resistance by the cuticle 4 increases.
従って、毛髪の逆方向摩擦力と順方向摩擦力との比をと
ると、この比は、健康な毛髪の場合は大きな値をとるが
、損傷した毛髪でキューティクル４の剥離が多くなると
、キューティクル４の先端での引っかかりが少なくなる
ため、逆方向摩擦力が健康な毛髪の場合と比べて小さく
なり、前述の比も小さな値となる。Therefore, if we take the ratio of the reverse frictional force and the forward frictional force of hair, this ratio will take a large value in the case of healthy hair, but if the cuticle 4 of damaged hair increases, the cuticle 4 Since there is less catching at the tip of the hair, the reverse frictional force becomes smaller than in the case of healthy hair, and the above-mentioned ratio also becomes a small value.
以上のように、毛髪の逆方向摩擦力と順方向摩擦力との
比を求めることによって、キューティクルの剥離の程度
、すなわち毛髪の損傷度を判定することができる。As described above, by determining the ratio of the reverse frictional force and the forward frictional force of the hair, it is possible to determine the degree of peeling of the cuticle, that is, the degree of damage to the hair.

As a result, the rotational direction of the contactor 13 is also reversed, and the reverse frictional force of the hair 11 is measured in the same way as the forward frictional force measurement, and the backward frictional force of the hair 11 is sent to the computer 19 as a digital signal. be remembered.

The rotation angle is detected by the servo galvanometer 24, and the drive current servo-controls the servo galvanometer 24 so that it always rotates and oscillates at a constant vibration angle. When friction occurs between the contact 23 and the hair 21 due to rotational vibration of the servo galvanometer 24, the drive current of the servo galvanometer 24 required to rotate the contact 23 changes depending on the magnitude of the frictional force. . This drive current is converted into a digital signal by an analog-to-digital converter 28 and input into a computer 29 to calculate the ratio of frictional force for rotation in the forward direction and in the reverse direction, that is, the ratio between the forward direction frictional force and the reverse direction frictional force. By doing so, the degree of hair damage can be determined.
