I want to buy a home laser hair removal machine, I want to ask friends who have used it, will it permanently remove hair?

This home is not going to be forever hair removal, is to destroy the hair follicles to inhibit the thickening of the hair follicles, that is, after using this will make your hair become very fine, long will not be so fast.

Laser energy can follow the hair shaft into the hair follicle inside, so that the sudden temperature, so that the hair follicle denaturation, atrophy, so that the hair stop growing, to achieve the effect of hair removal. Because this laser energy can penetrate the dermis layer of the skin, for the melanin hair follicles have selective thermal destruction, so do not damage the surrounding skin tissue.
