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 a light that is absorbed by the pigment
(melanin) in the hair. The light energy is converted to heat, which damages the tube-
shaped sacs within the skin (hair follicles) that produce hairs. This damage inhibits or
delays future hair growth.
Although laser hair removal effectively delays hair growth for long periods, it usually
doesn't result in permanent hair removal. Multiple laser hair removal treatments are
needed for initial hair removal, and maintenance treatments might be needed as well.
Laser hair removal is most effective for people who have light skin and dark hair, but it
can be successfully used on all skin types.
