Laser hair removal is a procedure to remove unwanted hair from the body by using a laser beam light with different wavelengths against the skin. The limits on strength or power used on a laser is carefully designed by countless studies conducted of the hair follicle to best match the laser light and pulse duration to the follicle size, depth and location in efforts to stop hair from re-growing. Laser hair removal is performed by a certified trained laser specialist or a physician, who places the positioning of the long pulse laser onto the skin. The laser works by ultimately destroying hair follicles that are in their active growth cycle at the time of treatment. A percentage of hair follicles are active at any given time while other hair follicles enter this active phase at different times, therefore, several treatments are needed to destroy all the hair follicles per given area.
A set of at least 6-9 treatments every 4-6 weeks are generally necessary to achieve significant hair removal with any laser system. Factors that determine the length of treatment include area to be treated, the texture of hair, frequency of treatments, history of waxing, tweezing, shaving, and depilatories, etc.
