Principle of Laser Hair Removal 2017

Laser hair removal is become the most common method for removing the hair for the unsightly body parts and Women mostly use these method as compared to men. It is commercially used since 1997 as the therapy of removing hair. According to FDA (food drug administration) of United States of America it is a permanent hair removal method. In this article we will discussed about the principle use in the hair removal through the laser.

SPTL (selective photo thermo lyses) is the primary principle adopted for the laser hair removal in which specific wave length light is thrown on to the selected body pats for specific duration to obtained the desired result with minimal or no effects on the surrounding tissue of the targeted tissues. Laser light absorb the dark target matter “melanin” and damaged the hair follicles which is responsible for the hair growth and does not effect the rest of the skin.

As melanin plays an important role in the laser hair removal which is also term as chromophore which is naturally present or if not naturally present then it is introduced in the body. Melanin have two main types Eumelanin and pheomelanin, first one gives black or brown color to skin while later one gives red or blond color to skin and hairs.

As photons present in the laser light are selectively absorbs so it is only effective in the dark and brown color skin and hair and is not used in blond or red color hairs and among the brown or black skin it works best in the light skin tone with the dark color hair but latest technologies are also effective against dark skin and hair color also.

Laser hair removal is the quickest and effective way of hair removal but still all of these results greatly depend upon the experience and skill of the person who is operating the laser. So all way hire the professional for hair removal with care, because their little negligence can lead to some serious health risks such as skin cancer.
