Laser hair removal is the process of hair removal by means of exposure to pulses of laser light that destroy the hair follicle.

Hair grows in several phases and a laser can only affect the current active growing hair follicles so several sessions are needed to damage the hair in all phases of growth and force it to revert to a vellus non-colored small hair.

Multiple treatments depending on the type of hair and skin color have been shown to provide long-term reduction of hair. Most patients need eight treatment sessions.
