Laser hair removal is a cosmetic procedure of removing unwanted hair by means of a laser beam. Highly concentrated light is directed into the follicles of the hair. The pigments in the follicles soak up the light which then results in destroying the hair. It may require multiple sessions with certain period of gaps until the hair stops growing.
The most common areas of hair removal in the body are – face, shoulders, chest, arms, underarms, legs, and bikini area. Any part of the body with unwanted hair can also be treated with laser.
Laser hair removal is not permanent as some may assume but, it reduces the number of unwanted hair. Once the hair follicles are treated with light beams, they stay in a state of dormancy for a long time and when the hair grows back, it becomes lighter, fewer, and finer.
It is estimated that 10 - 25% of your hair will be reduced after the initial session and will eventually reduce. It takes longer for the hair to grow back unlike waxing and, shaving.
