The laser used in hair removal is an intense and concentrated beam of monochromatic light. It incidents on the skin leaving it intact, as it is absorbed by the melanin of the strain and the hair bulb, destroying it only selectively, without affecting the surrounding tissue (phenomenon of selective photothermolysis). Because hair grows in a cyclical manner, repeated treatments of laser hair removal are required for total hair destruction. Gradually and selectively, cells that produce hairs are destroyed. 

Process of laser hair removal

Before each session, the laser machine requires adjustment of several parameters by a dermatologist. These settings are the key to the successful outcome of each session. The parameters covered are: energy, pulse duration, frequency, cooling, the diameter of the beam of laser, etc. All these require specialized knowledge and experience of dermatology in laser hair removal. However, it is not uncommon for people without the specialty of dermatologist to try to handle laser machines, resulting in lack of efficacy or the occurrence of adverse reactions. The execution of the session and a scan of the treated area is performed by properly trained medical or nursing staff. The machines, with which the laser hair removal is performed, are equipped with special cooling devices that reduce irritation and protect the skin from overheating and transient pigmented lesions.
It is very important that each laser hair removal session to be done at the appropriate time, since the hairs that are in the early anagen phase (the ones that have just occurred) have higher percentage of radical destruction. Indicative, laser hair removal treatments on the face are performed every 4 weeks, on body, armpits, and bikini every 6-8 weeks and on the legs every 8 weeks.
The number of laser hair removal sessions needed depends on many factors such as:
  • the area treated
  • the quality of hair
  • age
  • coexisting hormonal disorders,
  • weight
  • medication taken
  • metabolism,
  • hereditary predisposition
  • and certain pathological conditions.

Results of laser hair removal

The percentage of hairs that are destroyed permanently in each laser hair removal session will vary depending on the area, with areas where the skin is thinner (eg, underarms and bikini) to respond more quickly, while areas with thicker skin (eg, back and chin) to respond more slowly. The reduction in hair growth after each laser hair removal session is 10-25%. The hairs that re-grow after treatment tend to be thinner.
In some cases, it may take some extra sessions where few remaining hairs are treated.
