The laser works to remove unwanted hair by producing a beam of highly concentrated light that is scanned across an area of the body. The pigment within the hair follicles of that area absorb the light emitted by the laser. The laser pulses for a fraction of a second, just long enough to vaporize the pigment, disabling several follicles at a time to reduce or significantly impede the hair re-growth. Hair grows in cycles, and in any given area on the body you may have various hairs all at different phases of the cycle. With laser hair removal, only the hair follicles that are in the active growth phase will be most affected.

After the laser hair removal treatment, the remaining hair may be patchy, since some hairs are more resilient than others. The results from a laser hair removal treatment may vary from one individual to another, based on factors such as hormonal hair growth patterns, hair type, color of hair, ethnic background and the specific area being treated.
