Does laser work for everyone?

The differences between electrolysis and laser treatments used to reduce hair are many, but the main difference is how energy is converted for destruction of the lower follicle. With laser, light energy turns into heat energy when a dark hair (or dark skin) absorbs the light and produces heat.

Think of two cats in the sun, one white and one black. When you touch them, which one feels hot? The black one, right?

Laser light works in much the same way. It must pass through the skin and into the lower tissues beneath the epidermis, including the hair follicle. The concentrated laser light is absorbed by the pigment (melanin) of the hair growing inside the lower portion of the hair follicle.

Hairs that are light and hairs in the resting (telogen) stage, dehydrated and close to the surface of the skin are not successfully treated with laser. The optimal condition for successful laser treatment is light skin growing very dark hairs. In those with dark skin, the epidermis may absorb the light as well, creating heat on the surface of the skin. 

This can lead to skin damage.


If the hair is dark colored, exactly in the actively growing stage and fully engaged in the depth of a well-hydrated follicle, chances are that it will absorb the light and heat of the laser adequately enough to produce destruction of the hair growth cells and thus, the hair.





Electrolysis uses three modalities of electricity to cause the destruction of the hair growth cells and the lower hair follicle. Each, or a combination thereof, causes the tissue to coagulate and renders the growth cells permanently disabled. The treatment is focused, exact and targets each follicle. The electrologist will work with you, your skin and comfort level to obtain the best results. Their skill will determine the success of permanency.

Electrolysis treatment for permanent removal is successful for hair of any color, thickness, depth in any stage of growth, with skin of any color.


Finally, the main difference between the two is how the FDA allows the methods to be labeled.


Laser can only be called “Permanent Hair Reduction.”


Electrolysis is the ONLY method that is:

“Permanent Hair Removal.”
