This method cannot be used on unshaven areas and has not been used to obtain any conclusions about the duration of the necessary hair growth cycle as mentioned in the previous paragraph
Also, it is not possible to measure and record any changes in hair shaft diameter size and growth rate during growth of the same hair shaft
[0006] Although measurements of hair density are also available through specialized devices that take photographs or images used for manual counting, this method does not give information on how hair density varies
[0007] Indeed, none of the available methods can precisely observe and record the dynamic changes of all parameters of the hair throughout its life cycle
[0008] Furthermore, all available methods are not practical for daily basic application and cannot benefit those who want to actually implement them in the medical sector

Embodiment Construction
[0043] Specific areas of skin to be used as research subjects on hairy body parts are preferentially those areas with naturally pigmented lesions such as moles, moles, lentigines, seborrheic keratoses, telangiectasias. These areas of damage can be easily located each time we need to review changes in all hair quality parameters. Small lesions (P) that are easily identifiable in the detection zone, as shown in Figure 1, can also help to map the specific location of each follicle. This simple technique will provide the observer with a good opportunity to observe the specific changes determined for each hair shaft during the time the hair is measured.
[0044] Without any prior skin preparation, only natural markers are used as an accurate marker, which can provide information on hair density, hair size and a rough estimate of whether individual hairs are growing over time compared to the actual image of the target point, as shown in Fig. 2. Follicle 1 shows a new hair tip emer...

A method of measuring hair quality in a predefined area of the scalp. The method addresses the preparation of the scalp and the process for measuring the density, the size of hair shaft, the length of each hair growing out from the area. A video capture device capable of storing images transferred from a camera, computer hardware and software capable of archiving the images and measuring the size and length of each hair shaft in the images. A method of dying hair shafts combined with above image processing techniques will provide measure of almost every phases of hair cycle. The end result will be the statistical data of the ratio of growing hairs and non-growing hairs with the average of hair growth rates and other data such as the maximum and minimum growth rate, the standard error, the variance etc.
Description
technical field [0001] The present invention relates to a method of measuring various hair quality parameters such as the diameter of the hair shaft, the growth rate of each hair shaft, the total time in each phase of the hair growth cycle. The method can be iterated to observe dynamic changes in these parameters so that the method can be used to study changes in these hair parameters due to food, drugs, specific products, activities and habits. Background technique [0002] Hair problems and diseases, especially body hair and thinning hair, are very common in both humans and animals. Thinning of body hair and hair is estimated to be due to many specific changes in the hair growth cycle. If there is a high percentage of body hairs and hairs on the body part concerned that do not perform the function of growing hair stems, then those body hairs and hairs are in the arresting or degenerative phase of the hair cycle. The resting hair will soon fall out, and at this stage, if ...
