What is laser hair removal?

Well, basically a laser is a very strong and very focused beam of light. Lasers are used in a huge range of applications, from industry, to communications, to mapping. Laser hair removal relies on specially designed medical grade lasers that are safe to use on human skin. So, laser treatment can either permanently reduce the density of the hair or permanently remove unwanted hair.

Permanent reduction in hair density means some hairs will regrow after a single course of therapy and patients will need ongoing laser treatment. Also, permanent hair removal means none of the hairs in the treated area will regrow after a single course of therapy and no ongoing laser therapy is needed.

Whether hair is removed permanently or just reduced in density is influenced by:

  1. The colour and thickness of the hairs being treated
  2. The colour of the patient’s skin.
  3. The type and quality of the laser used.
  4. The competence and training of the person operating the laser.

Laser hair removal and how does it work

Laser hair removal works because the light of the laser beam can be converted to heat. The light is attracted to the pigment (melanin) in the hair. Dark pigment absorbs the light and the converts it to heat. The heat then affects the hair follicles to prevent hair growth.

In order to destroy a hair follicle, the bulb of the hair follicle where the blood supplies the hair with oxygen to grow needs to be destroyed as well as the stem cells which are responsible for hair regeneration. To be able to do this, a temperature of about 70 degrees needs to be reached.

The darker and the thicker a hair is the more pigment it will hold, and the more light it will absorb. This is why it is important that you don’t wax or pluck your hair before a treatment, because if there is no hair there, there is no way for the laser light to treat that hair follicle.
