Laser hair removal is the process of removing unwanted hair by means of exposure to pulses of laser light that destroy the hair follicle. Lasers can cause localized damage by selectively heating dark target matter, melanin, in the area that causes hair growth, the follicle, while not heating the rest of the skin . Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged. If you are planning on undergoing laser hair removal, you should limit plucking, waxing, and electrolysis for six weeks before treatment. That’s because the laser targets the hairs’ roots, which are temporarily removed by waxing or plucking.
