How Does Laser Hair Removal Work?

So many of us have unwanted hair on some part of our body. On the legs, back, chest, arms, face – seems we all have an area that we would like to be hair free.
Possibly the greatest advance in hair removal is laser hair removal. But, how does laser hair removal work?

The process itself starts with selective photothermolysis – SPTL, for short. This matches a wavelength of light, with pulsating action, to effect the desired area positively (hair removal), without effecting the surrounding area negatively (burning).

The laser light is directed at the hair in the area for removal. The melanin (the compound that gives color to hair and skin) then absorbs the light. This, in turn, destroys the hair follicle, making it unable to produce hair.

With that said, darker hair will be the most successful for removal. Lighter hair will be more difficult because it does not have the pigment.

There are a variety of different lasers available, for home and professional use. There is the Ultimate Light or Pulsed Light, Diode, Nd: Yag, Ruby, and Alexandrite. Though all of the basics of laser hair removal are the same, all of these lasers run at different wavelengths. Which laser is used is really a matter of preference with the specialist. When you interview specialists, they should go over the options they have available with you.

There are now thousands of accredited clinics that perform laser hair removal. It is best to interview several licensed / accredited clinics and specialists, to find what works best for you.
On the skin, it may feel like a little tingle, little pinch or snapping of a rubber band. To some people, it wont feel like much of anything. It just depends on the person.
You will need at least a few sessions, and possibly more, as hair growth and density is different for each person.

The cost will range depending on the size of the area, hair density, the clinic you use and other factors.

With the latest scientific advancements, you can now do laser hair removal at home. Some of these devices use light and heat. The No No Hair Removal system uses heat only, so it can be used on all hair colors.

If you decide to have laser hair removal at a clinic, you will be able to ask the technician questions including the type of laser they have, how does laser hair removal work and other concerns you may have.
