What Is the Procedure for Laser Hair Removal?

The science underlying laser hair removal is explained here. The hair on our body grows out from specific regions of the skin (dermal), known as hair follicles. The hair follicle is the particular region from which the hair follicle stems.

When hair grows out of a strand, it gets longer, and some end up on the skin. Whatever hair length we observe above the skin is just a part of the total hair length. The hair root is attached to the follicle. The follicle is permanently present in the skin. Even if hair falls out, new hair will grow from the follicle.

To obtain smooth skin, we use various hair removal processes such as shaving, hair removal creams, and waxing. But none of these hair removal techniques can permanently remove the hair because they act superficially only on the hair strand. None of these standard hair-removal techniques targets the hair follicles. The only approved process is laser hair removal to permanently remove the hair from the follicles.

Science of Laser Hair Removal Process

When laser rays are applied to the skin, they reach the hair follicles in the deeper skin layers beyond superficial skin. The rays damage the skin hair follicles to a certain degree, so they cannot grow any new hair. When the hair follicles cannot grow any more hair, hair does not appear on the skin. This helps almost permanently to stop the problem of body hair.

The scientific process revolves around using the properties of laser rays on the skin. The laser rays are a beam of high-intensity laser light. The laser beam penetrates through the top skin layers and reaches the hair follicles deep inside the skin layers.

When the light hits the follicles, it transduces into the heat energy and destroys the regeneration power of the follicles so no more hair can grow from them. The heat energy, when running down the follicles, makes the existing hair shaft fall off and causes damage just enough to stop the growth of hair from the follicles.

The laser rays render the follicles dormant and lead to a stoppage of hair growth. Laser hair removal does not lead to permanent blockage of hair growth just after one or two applications. Still, it makes the hair follicles ineffective and permanently dysfunctional after a few applications. A single hair removal session can reduce body hair growth by around 25%.


Most people are in a dilemma, does the hair come back after the laser hair removal process? There is a simple science to explain this. It takes at least six rounds or sessions of laser treatment to make the hair follicles incapable of giving rise to more hair shafts. Let us understand hair growth cycles.

At any time, the skin hair is in either of any of these three stages of hair growth:

  • Anagen Phase( hair growth phase)
  • Catagen (transitional hair phase)
  • Telogen (hair follicle resting phase)

The laser rays mainly affect the hair in the anagen phase. Anagen is usually the most extended phase in hair growth and generation. Laser treatment primarily works on the hair in the anagen phase. So, it takes repeated laser treatment sessions to catch up with all the hair in its anagen phase. Several individual differences in the hair growth process affect the success rate of laser treatment.

Some people’s hair follicles are more well-developed than others. More than six laser sessions may be needed for them to eradicate the skin hair growth process. Identifying skin type and other physiological conditions is crucial before opting for any hair removal process. Because their follicles repair more quickly in some people, they require more laser hair removal treatments to limit hair growth.

People also have certain pathophysiological conditions affecting their hair growth that can be influential during laser hair removal application. Book your appointment today and get smooth, hair-free skin with the complete scientific and trusted laser hair removal process. There are some follow-up processes for laser hair removal.

First, any skin that has been laser-treated should not come in direct contact with the direct sun rays because it can aggravate skin infections and diminish the effectiveness of the treatment. Always use sunscreen on laser-treated skin.
