た。2. Description of the Related Art Gloss of hair indicates the degree of hair damage and fatigue, that is, the degree of health of hair, and is a major factor in the appearance of hair. It is also an important index for judging the effects of hair cosmetics such as shampoos, rinses and hair styling. For this reason, measurement of the gloss of hair has been conventionally performed by various methods.

This method is a visual evaluation method. However, in order to perform an objective evaluation by this method, specialized knowledge and experience are required, and there is a drawback that it cannot be easily carried out at a sales site or the like. In particular, in recent years, the number of colored hairs has increased, and it has become more difficult to visually evaluate the gloss.

一定方向とすることが可能となる。An appropriate amount (number) of the hair 6 whose gloss is to be measured is sandwiched between the gaps 2. As shown in FIG. 2 and FIG. 4, the gap 2 has a structure in which one side is open, this portion is wide, and becomes narrower toward the inside to pinch the hair. The width of the gap 2 can be appropriately determined, but it is generally preferably about 1 to 3 mm, particularly preferably about 1 to 2 mm at the portion where the hair is sandwiched. Also,
As shown in FIG. 3, the gap 2 has a structure that communicates widely from the near side to the far side. Therefore, if the hair is sandwiched in the gap 2, the hair is inevitably in the longitudinal direction and the light irradiation direction (light source). 3a, 3b and the direction connecting the light receiving section 4) are substantially the same. As described above, it is preferable that the longitudinal direction of the hair and the light irradiation direction coincide with each other, but it is not always necessary that they coincide completely, and an error of about 30 to 45 ° is allowed in actual measurement. With such a structure of the gap, the hair can be easily caught, the amount of the hair to be sandwiched is automatically adjusted to be almost constant, and the light irradiated to the hair can be directed in a certain direction.

In the device shown in FIGS. 1 to 4, the light source 3a and the light receiving portion 4 are arranged at a substantially right angle (90 °) through the hair surface, and the light source 3b and the light receiving portion 4 are arranged at almost 45 ° through the hair surface. Have been. Light from the light source 3a is applied to the hair surface at an incident angle of 45 °, and is sensed by the light receiving unit 4 as regular reflected light. Similarly, the light from the light source 3b is also reflected on the hair surface, but only the light diffusely reflected at an angle of 45 ° is detected by the light receiving unit 4. The light source used here is a light emitting diode (LED)

ができる。The basic principle of measuring the gloss of the hair with the instrument of the present invention is as shown in FIG. 9, the regular reflection (incident angle θ 1 , reflection angle θ 1 ′) of the light emitted from the light source 3a and the light source The diffuse reflection (incidence angle θ 2 , reflection angle θ 1 ′) of the light emitted from 3b is measured, and the gloss of the hair is determined from the difference between these intensities. Therefore, various modifications can be made to the device of the present invention as long as this principle is used. For example, the angle of incidence of the light emitted from the light source can be appropriately changed, and a single movable light source can be used instead of two or more light sources. Furthermore, it is also possible to provide a plurality of light receiving units instead of the light sources. These changes can be made in consideration of economy, accuracy of measurement, and the like.
