Laser works on dark hair only. The treatment consists of first shaving the area to be treated to direct all the laser energy below the skin where the papilla (root) is. Then the laser is scanned over the area. The dead hairs fall out on their own, usually in about three days. Patient returns for their next treatment in about 6 weeks and eventually take a total of three to seven treatments.
