Laser Hair Removal: Preparations Tips, Process, and Pros Cons – Removing hair by shaving, plucking, or waxing often only lasts a moment. Recently, many people started trying laser procedures to remove hair, as the results proved to last longer. However, the procedure also carries some risks, such as reddish skin and pain.
The laser procedure for hair removal is performed by emitting high-strength rays on the roots (follicles) of the hair. The energy of this laser beam is absorbed by a dye or a melanin substance in the roots of the hair, then converted into a heat energy that damages the roots of the hair itself.
It usually takes 2-6 times the laser procedure with a pause of several weeks, to be able to remove the hair in the desired area perfectly.
Lasers do not permanently remove hair. Hair can grow back in a few months or several years. However, the growing hair will be fewer, thinner, and not as dark as before. The laser action can be repeated when the hair grows back.
