Hair growth comprises three stages. Laser technology is designed to treat hair in its active, or anagen, phase of growth when it contains the most pigment.

Highly concentrated light is transmitted 1-5 millimeters into the skin. The light targets the melanin, or pigment, in hair follicles. The pigment absorbs the light, where it is converted to heat, causing thermal damage to the follicle without harming the surrounding skin. The follicle is then disabled, and hair regrowth is prevented.

Several factors determine the number of treatments required to achieve the desired results: the rate of hair growth, the type of hair (coarse or thin) and the color of hair. Each varies between individuals and different body areas. While most patients report a significant reduction in hair growth after one or two laser sessions, additional laser treatments are usually necessary to achieve the desired effect.

Areas which are commonly treated include women’s upper lip, chin, bikini, legs and underarms; and men’s shoulders and backs. Additional treatment sites include the nose, ears and buttocks.
