What laser light does to hair follicles during treatment

The mechanism of laser hair removal fits in one sentence, and that sentence carries more constraints than it first appears to.

The one-sentence version

www.plasticsurgery.org explains that the laser light is absorbed by the pigment in the hair shaft, and the heat generated in the follicle damages the follicle to inhibit future hair growth.

Reading the sentence for constraints

The sentence has three links. Pigment in the hair shaft is the first, heat is the second, and damage to the follicle is the third. Each link depends on the one before it.

ASPS covers the wider picture in what you need to know about laser hair removal, which is the place to go once the mechanism makes sense.

Where a complicated case departs

The source's verb is inhibit. That is a narrower word than eliminate, and it is worth keeping in mind when you picture the outcome.

For a reader in Ypsilanti weighing a course of sessions, the useful question is not whether the light works in general. It is whether this chain applies to your hair and your skin.

The compromise

Take the mechanism as stated: absorption by pigment, heat, and follicle damage that inhibits future growth. Then ask a provider how that chain applies to your case, and what they would do if one link does not.

The caveat that stays attached

Only someone who examines your hair and skin can say whether that chain holds for you.
