Laser hair removal is the deliberate removal of body hair using the technology of laser. Thicker hair can often be in unwanted places or too excessive, laser hair removal is directed towards the removal or reduction hair.
Laser hair removal works by targeting the hair follicle with laser light, this energy damages and goes on to destroy the hair follicle, thus stopping the follicle from producing further hairs. The laser delivers an intense beam of light, which is absorbed by the hair follicle whilst the surrounding tissue remains unaffected.
This process is called selective photothermolysis (photo means light and thermolysis means to destroy with heat). It is selective as it targets hair and not skin.
Laser hair removal is not electrolysis. Electrolysis works by directing an electric current into each individual hair follicle which is painful and time consuming. Laser can target a large amount of hairs in one go virtually pain free.
What You Will See:
The dead hair coming through the skin is shed after 1 – 3 weeks. During this period the hairs will seem to ‘grow’ as they are pushed out by the new skin. After the 2nd treatment, depending on skin and hair type the area can begin to look patchy.
The skin may be red immediately following a treatment and the hair follicles where the skin has been treated may be raised and bumpy, this usually subsides within a few hours but can take up to 48 hours on some people. A few people experience itching a few days later as the hair is pushed out.
Length of Treatments:
The laser light affects only those hairs which are actively growing in the anagen phase. Different hair follicles will be in different hair growth stages at any one time. These hair growth cycles can vary between a few months and a year and for this reason it requires several sessions to ensure that we catch all hairs during in anagen phase.
Treatment is conducted every 4 weeks on the face and every 6-7 weeks on the body. The required number of treatments varies, but usually 6-8 are needed for optimum results. This means a full course of treatments on the face usually takes about 7 months and on the body the average is about 11 months.
Duration of Treatment:
Laser hair removal sessions can take from as short as 5 minutes and go up to an hour in length, depending on the size of the area being treated. For example, the upper lip takes only 5 minutes whereas treating the full legs or back could be at least 45 minutes.
