Color light depilation can achieve good depilation effect, but why should a course of treatment go through several times? Let’s take a look at the professional explanation of experts!
Why does color light depilation go through several times in a course of treatment? Plastic and cosmetic experts explained that color light depilation has a certain high-tech content and strong physical foundation. The main principle is the application of a physical concept, that is, the material of a certain color must have the strongest light absorption rate of a special wavelength. In the hair follicle of our black hair, the hair nipple is rich in melanin. This melanin has a strong absorption rate for monochrome laser with special wavelengths of 775nm and 800nm. After absorbing the light wave, it will produce a thermal effect on the hair follicle. If the hair follicle necrosis occurs, the hair will stop growing, so as to achieve the purpose of hair removal.
Color light depilation generally requires three to six times, or even more times, mainly due to two factors:
First, most hair follicles are bound together in groups of three and open in the same pores. A hair in the pores is the hair growing from one of the three hair follicles in the group below it. Therefore, one treatment can only destroy one hair follicle in a group;
Second, because the hair growth cycle has three stages: growth period, degenerative period and resting period, only the hair in the growth period can be effectively removed. Therefore, in order to achieve permanent hair removal, we must go through several treatments. Effective laser treatment should basically have no hair growth within one month after treatment.
It is important that after treatment, it does not affect work and life, so it is also called “midday beauty”.
