Laser hair removal is a medical procedure that uses a concentrated beam of light (laser) to remove unwanted hair.

During laser hair removal, a laser emits light that is absorbed by the pigment (melanin) in the hair.

Light energy is converted into heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hair. This damage inhibits or delays future hair growth.

Although laser hair removal effectively delays hair growth for long periods, it usually does not result in permanent hair removal.

Multiple laser hair removal treatments are required for initial hair removal, and maintenance treatments may also be needed. Laser hair removal is most effective for people who have light skin and dark hair, but can work well on all skin types.
