Laser Hair Removal 101

How Does it Work?

Laser light is absorbed by the hair shaft, damaging the follicles and thereby stunting hair growth. The result is temporary to permanent hair loss in the affected area.

Laser hair removal is based on the principle of selective photothermolysis, the technique used in microsurgery to target specific tissues. The laser matches the tissue and heats it without damaging any of the surrounding areas.

The procedure has to be done regularly in a clinic in intervals of 2-3 weeks every 1, 3, 6, 9, and 12 months by a professional aesthetician or at home. Not all devices are the same, so it is recommended to use only the best IPL products to avoid any adverse effects. The most popular brands include: Braun, Gillette, Tria, and Remington.

Hair Reduction and Regrowth

Studies have shown that patients can have either temporary or permanent hair loss with the procedure. Almost 100% of patients experienced temporary hair loss while at least 90% had permanent hair reduction after a year of treatments.

The efficacy of last hair removal largely depends on the combination of skin color and hair color. Those with less melanin, e.g. those with blonde hairs, have less melanin so the treatments are less effective. Those with contrasting skin tones and hair color, e.g. dark hair with fair skin, have the best results.
