Permanent hair removal
Laser permanent hair removal
During sessions of permanent hair removal, hair is permanently destroyed and the follicles "burned", becoming unable to regrow hair.
However, in the aftermath of a comprehensive treatment of permanent laser hair removal, a few new hairs will appear. It's actually kind of “hair down”, which, over the years, will become thicker.
The time to onset of new hair is usually 2 to 5 years or more. A second session of laser hair removal will be necessary at this time, but there will never again be need for a complete treatment of five sessions.
Does permanent hair removal increase skin cancer risk?
The laser and flash lamp used in permanent hair removal are not responsible for skin cancer. Skin cancers are caused by "ionizing" radiation, that is to say carcinogens such as ultraviolet rays (UV).
In permanent hair removal, lasers and flash lamps do not emit UV light, but visible light (from violet to red) or high power infra-red (YAG). The wavelengths of visible light and infrared are not carcinogenic.
Tweezing:
This is the classic technique of hair removal performed by the person herself with tweezers. It runs the risk of ingrown hairs as a result of pulling the hair out, and inflammatory spots or pimples caused by bacterial contamination.
Waxing:
Usually performed by a beautician in a salon or by the person him or herself, the technique of waxing also exposes the risk of ingrown hairs and therefore skin infections by bacteria (creating folliculitis or abscesses) or by viruses (molluscum contagiosum, herpes...). This happens most often when the wax is re-used.
Techniques for permanent hair removal or long-term
Electrolysis and laser or lamp hair removal are techniques that destroy the hair bulb. These are commonly called permanent hair removal because the destruction of the hair is considered almost final.
Please note:
Laser and lamp hair removal are very long term, but nothing is permanent. It is still possible that under the influence of various factors (including hormones), soft, downy hair adjacent to the destroyed hair will begin to become thicker and darker over time. The result on the area of hair is very long term, but there can always be a regrowth of hair in the treated area.
