Description
la METHOD OF MEASURING HAIR STATE
SUCH AS HAIR FRIZZ AND HAIR VOLUME
FIELD OF THE INVENTION
The present invention relates to a method to more precisely measure hair state such as hair frizz and hair volume.
BACKGROUND OF THE INVENTION
Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scalp. The soiling of hair causes it to have a dirty feel and an unattractive appearance. The soiling of the hair necessitates shampooing with frequent regularity.
Shampooing cleans the hair by removing excess soil and sebum. However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.
A variety of approaches have been developed to condition the hair. These approaches range from post-shampoo application of hair conditioners such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to both clean and condition the hair from a single product.
A common method of providing conditioning benefit to the hair is through the use of hair conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point oils, silicone compounds, and mixtures thereof.
Most of these conditioning agents are known to provide various conditioning benefits such as moisturized feel, softness, and static control to the hair.
There has been a desire for a method of measuring hair state such as hair frizz and hair volume for the purpose of, for example, evaluations of hair conditioning agents/compositions, and some methods have been developed. For example, WO 01/68051 discloses "Image Analysis Protocol" which is a system and procedure which is designed to digitally measure hair areas by a digital camera, and analyze the components of bulk hair area and flyaway hair area which in turn form the total hair area. This method is based on two dimensional image analyses. However, it has been found that such two dimensional image analyses are not sufficient to precisely evaluate the hair state.
Based on the foregoing, there remains a need for a method to more precisely measure hair state such as hair frizz and hair volume.
None of the existing art provides all of the advantages and benefits of the present invention.
SUMMARY OF THE INVENTION
The present invention is directed to a method of measuring hair state comprising following steps:
(a) setting a light emission element to emit a light to a hair sample, and setting a light receiving element to receive the light which is reflected by the hair sample;
(b) placing the hair sample at a position which is within the focal area of the light;
(c) irradiating the light from the light emission element to the hair sample;
(d) receiving the reflected light by the light receiving element;
(e) converting the received light to the position of the surface of the hair sample by triangulation;
and (f) evaluating the state of a certain portion of the hair sample and/or overall the hair sample by using the position of the surface of the hair sample.
The present invention can provide a method more precisely measure hair state including, for example, hair frizz, hair volume, flyaway, and hair style, by the above three dimensional measurement of the hair.
The present invention is also directed to an equipment of measuring hair state comprising:
(a) a light emission element to emit a light to a hair sample (b) a light receiving element to receive the light which is reflected by the hair sample;
(c) a conversion element to convert the received light to the position of the surface of the hair sample by using triangulation; and (d) an evaluation element to evaluate the state of a certain portion of the hair sample and/or overall the hair sample by using the position of the surface of the hair sample.
These and other features, aspects, and advantages of the present invention will become better understood from a reading of the following description, and appended claims.

METHOD OF MEASURING HAIR STATE
The method of measuring hair state of the present invention comprises following steps:
A method of measuring hair state comprising following steps:
(a) setting a light emission element to emit a light to a hair sample, and setting a light receiving element to receive the light which is reflected by the hair sample;
(b) placing the hair sample at a position which is within the focal area of the light;
(c) irradiating the light from the light emission element to the hair sample;
(d) receiving the reflected light by the light receiving element;
(e) converting the received light to the position of the surface of the hair sample by triangulation;
and (f) evaluating the state of a certain portion of the hair sample and/or overall the hair sample by using the position of the surface of the hair sample.
Fig. 1 illustrates a preferred embodiment of the measurement of hair state of the present invention. In the illustrated embodiment as shown in Fig. 1, the hair sample is placed in front of a center plane (x-z plane at y=0) at a position which is within the focal area of the light, and the position of the surface of the hair sample is the distance y of the surface of the hair sample from the center plane.
The light emission element used in the method of the present invention includes, for example, line laser, circular laser, LED, and halogen lamp. Preferred light emission element is line laser and circular laser, more preferred is line laser as shown in Fig. 1 in view of accurate measurement especially when used with CCD with higher spatial resolution. The wavelength of the laser can be from about 100nm to about 10micron, preferably from about 450nm to about 800nm, more preferably from about 550nm to about 700nm in view of precise measurement especially when using CCD camera as the light receiving element, and in view of commercial availability. The light receiving element used in the present invention can be any two dimensional sensors such as CCD, CMOS, PSD, and InGaAs. Preferred is CCD as shown in Fig.
1 in view of precise measurement. The resolution of CCD is at least 320x240 dotts. In the illustrated embodiment shown in Fig.l, CCD has 300micrometer spatial resolution. Although it is not shown in Fig. 1, the light receiving element such as CCD is preferably connected to a computer for the conversion of the received light to the position of the surface of the hair sample such as the distance y by triangulation and/or for the evaluation of the hair state.
The conversion of the received light to the position of the surface of the hair sample, i.e., the distance y of the surface of the hair sample from the center plane is made by triangulation.
For the evaluation of the overall hair volume, the hair sample can be scanned in whole, i.e., from root to tip and from right side to left side. For the evaluation of hair frizz, the hair sample can be scanned in whole, or a certain area of the hair sample can be scanned.
The evaluation is made with or without the reproduction of the structure of the hair sample in three dimensions on the screen of computer which is connected to, for example, the light receiving element such as CCD. For example, the evaluation of hair state is made with the reproduction of the structure of the hair sample in three dimensions and made by showing the hair in different colors based on the distance y of the surface of the hair sample from the center plane.
Fig. 2 shows an illustrated embodiment of hair samples for the evaluations which results are shown in Fig. 3 and 4. Fig. 3 is an illustrated embodiment of the result of the evaluation of hair state, especially hair frizz according to the measurement method of the present invention. In Fig.3, the horizontal axis shows the distance y which is a distance of the surface of the hair sample from the center plane, and the vertical axis shows the percentage of hair volume compared to the hair volume at y 10. In Fig.3, Sample A shows a larger percentage at y=30 or more, i.e., larger amount of hair volume compared to Samples B and C at y=30 or more. Larger amount of hair volume at a certain distance such as y=30 or more means expanded hair and/or hair which is not aligned well, i.e., larger amount of hair frizz. Fig. 4 is an illustrated embodiment of the result of the evaluation of hair volume according to the measurement method of the present invention. In Fig.4, Samples A, B and C show clear differences in the amount of hair volume. The evaluations shown in Fig. 3 and 4 can be made with or without the reproduction of the structure of the hair sample in three dimensions.
