Laser hair removal works by using a targeted laser to slow down follicular hair growth. Eventually, the growth becomes so slow that it takes months – if not years – for the client to see new hair growth at the treatment site.
So while laser hair removal results aren’t permanent, they can last for such a long time that they feel permanent!
During your laser hair removal treatment, a technician uses a handheld laser unit that emits a concentrated beam, set at a wavelength that targets the melanin in the hair and/or at the follicle growth center (called the hair bulb).
The laser beam passes through the skin and is absorbed by the melanin in the hair follicle. This causes the hair follicle to heat up and eventually fall out. A new hair will grow back in its place, but at a slower rate.
Over time and with a set number of laser hair removal treatments (usually six to eight sessions), hair regrowth will slow down to the point where the skin is smooth and hair-free for several months before a maintenance session is needed.
