Laser hair removal: how does it work?

Laser hair removal is a permanent hair removal technique that is based on the principle of selective photothermolysis. It primarily targets melanin , which is the pigment responsible for the colour of hair. Indeed, the laser emits an infrared radiation that is absorbed by the melanin. This melanin then transfers this energy along the hair shaft to the hair bulb and this heat destroys the hair follicle. Once the bulb is destroyed, the hair can no longer regrow.

This technique is particularly effective when the hairs are in the anagen phase, that is, the growth phase, as it is at this point that the melanin rate is at its highest. However, this method does not work on blonde, very light or even white hairs, as these are simply devoid of melanin and the laser is not sensitive to it. Generally, 5 to 6 sessions of laser hair removal every six weeks are necessary to eliminate the hairs.

Laser hair removal during pregnancy: is it possible?

Eliminating rapid hair regrowth during pregnancy is possible, but laser treatment is not the solution to adopt. Although there is no evidence thatlaser hair removal is harmful to your future child, specialists do not recommend it as a precaution.

Indeed, pregnancy is characterised by hormonal fluctuations, such as an increase in androgen hormones, such as testosterone. This hormone secretes dihydrotestosterone (DHT), known for shortening the anagen phase (growth phase) and increasing the telogen phase (shedding phase) of hair, although its mode of action is not yet clear. Consequently, hair can regrow even after a treatment session, which equates to a waste of time.

A pregnant woman facing hyperpigmentation of the skin, particularly a pregnancy mask, should avoid laser treatment which easily targets melanin and risks causing burns on the skin. You also risk the appearance of permanent unsightly spots and unwanted scars caused by the burns.

Waxing is an appealing alternative if you wish to remove your hair during pregnancy. Whether it's cold, lukewarm or hot, wax is not dangerous as it does not penetrate the skin barrier. However, it is advisable to avoid hot wax which can cause slight dilation of the blood vessels, promoting venous problems that are already common during pregnancy. The shaving can also be recommended for pregnant women if you struggle with the pain caused by waxing.

Note : It is possible to resume laser hair removal approximately 2 to 6 months after your pregnancy. It is recommended to consult a qualified professional who will help you determine the optimal time for your individual situation.
