Laser hair reduction is a medical procedure used to remove excessive and cosmetically disabling hair . It uses a concentrated beam of light (laser) to remove unwanted hair. The light emitted by the laser is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages hair follicles within the skin which in turn will inhibit or delays future hair growth. Laser hair removal is most effective for people who have light skin and dark hair and it is less effective for hair colors that don't absorb light well: gray, red, blond and white.
The number of treatment sessions required ay vary from 8-12 sessions and spacing between treatments depends on the body area being treated. Inadequate response to the treatment warrants hormonal evaluation and if any abnormality is detected, treatment of the same is advised.
If you are planning on undergoing laser hair removal, you should limit plucking or waxing for four to six weeks before treatment. That's because the laser targets the hairs' roots, which are temporarily removed by these procedures. Shaving is the only acceptable method of hair removal during the entire course of your laser hair reduction treatments.
Please refrain from tanning your skin either with direct sun exposure or artificial tanning products for at least 3 weeks before your laser hair removal appointment.
