Is laser hair removal permanent and what are the risks?

The word “definitive” is a dangerous term, in any case excessive, in terms of laser hair removal. Indeed, after a session, the treated zone appears well depilated and, in theory, all the hair bulbs present were destroyed. However, non-pigmented resting hair bulbs, which have escaped the action of the laser, will progressively activate and give rise to new hairs. Hair removal will last a few weeks, before a regrowth appears: a new session of laser will then be necessary. It will be followed again by a phase of depilation, then a new regrowth, less important than the previous one however. In fact, as the sessions repeat, the regrowth will be more and more discreet.

At the armpit, jersey or abdomen level, it can be reasonably assumed that after five or six sessions the patient can hope to show only a small and discrete hairiness, with a hair reduction of more than 80%. That the persistent hairs are generally very fine, and therefore not very visible. In the face, the number of sessions is unfortunately higher, especially if there are associated hormonal abnormalities. Once a satisfactory result is obtained, a maintenance session every 12 to 18 months can perpetuate the effects.

What is the optimal rhythm of the sessions?

Laser hair removal etobicoke treatment destroys in a way a generation of hair bulbs. It is therefore necessary to wait until new hairs appear before considering a new session. This time is very variable according to the regions, much faster on the face, slower on the limbs. Thus, just after a session it is not possible to know when the next one will take place, which will be practiced when the patient will see again a little hairiness.

What are the risks and side effects?

Laser hair removal is a technique nowadays extremely practiced in Etobicoke on probably several tens of thousands of patients per year. The number of incidents observed, compared to the actual frequency of this act, is very low. Most side effects are mild. The most problematic side effect is burning which can be followed by depigmentation of the skin. The elective target of the laser hair removal is the pigment of the skin, that is to say melanin.
