The Principles Behind our Hair Removal technique

Selective Photothermolysis is the name given to a process in which the hair is selectively heated to a much higher temperature than the skin through the action of light.

Melanin, the chromophore which colours the hair and which is also present in the inner and outer sheath, absorbs light from the laser, becomes hot and passes this heat on to the hair itself. The proliferative region of the hair follicle responsible for the actively growing hair is then heated because of its proximity to the hair shaft. If these cells are heated to a temperature greater than 65 degrees, the protein making up the cells will coagulate and these cells will die.

The death of these actively dividing cells of the hair bulb section of the hair follicle results in an inactive follicle no longer capable of producing hair. Death of a proportion of the cells only, results in the miniaturisation of the follicle with the result that the hair will grow finer on return. Death of some of the melanocytes, the cells that five colour to the hair, will result in a fairer hair returning.

So from this you will see that the degree to which the hair is heated is absolutely critical to the achieving a permanent result of the treatment. Too low a fluence ( the energy setting on the device) will result in insufficient heat to kill the cells responsible for hair growth. This is most often the outcome of the treatment with devices such as pulsed light systems used at beauty salons and non specialist centres. Too much energy and the skin pigment ( also melanin) will absorb sufficient light to heat the germinal cells of the epidermis resulting in an aggressive response.

We have successfully performed over 60,000 procedures and are eminently qualified to produce results which are permanent at our hair removal clinic in Markham. Our medical lasers are the most advanced systems in the market for hair removal and you can rest assured that they generate the appropriate  amount of energy to generate the heat required to cause the coagulation of the cells.
