As we all know, Chinese hair is black because it contains melanin particles. These melanin particles are the target tissue of laser therapy.
The laser can pass through the epidermis and enter the dermis, which is selectively absorbed by the melanin particles in the hair and hair follicles, resulting in photothermal effect. The heat energy in the hair can be transmitted to the surrounding, completely destroying the “hair roots” such as hair follicles and stem cells, and permanent hair removal. The normal tissue around the hair follicle does not absorb this laser because it does not contain melanin particles, so it is less affected and generally will not cause scar. 800 nm, 100 ms laser hair removal machine has very advanced performance.

Laser hair removal generally takes three to six times, mainly due to two factors: first, most hair follicles are bound together in groups of three and open in the same pore. A hair in the pore is the hair growing from one of the three hair follicles in the following group, so one treatment can only destroy one hair follicle in a group; Second, hair growth should go through growth period, degenerative period and resting period. Laser hair removal in growth period is 75% effective, degenerative period is 25%, and resting period is almost invalid.
