Permanent Hair Reduction By Laser

The laser light is absorbed by the pigment called melanin which is present in the root of the hair follicle.

This light energy penetrates through the skin is converted into heat energy. The heat thus formed bursts the melanin pigment which in turn destroys the hair follicle.


The amount of light absorbed depends:

  • colour of the skin.
  • colour of the hair.
  • thickness of the hair follicle.
  • wavelength of the light.
  • spot size.

The best absorption is seen in fair skinned individuals with thick, dark and coarse hair. Optimum energy has to be decided to attain maximum benefits with minimum side effects. Lighter skin individuals have less amount of melanin in the skin therefore less amount of energy is absorbed by the skin. This laser light does not work on gray or white hair, as gray or white hair does not have melanin.
