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. The light energy is converted to heat, which weakens the tube-shaped sacs within the skin (hair follicles) that produces the hair. This process slows future hair growth.
Laser hair removal effectively delays hair growth for extended periods of time. Multiple laser hair removal treatments are required for initial hair removal, and maintenance treatments may also be needed.
