Laser hair removal
process of removing unwanted hair by means of exposure to pulses of laser light
Laser hair removal is the process of hair removal by means of exposure to pulses of laser light that destroy the hair follicle. It had been performed experimentally for about twenty years before becoming commercially available in 1995–1996. One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998. Laser hair removal is widely practiced in clinics, and even in homes using devices designed and priced for consumer self-treatment. Many reviews of laser hair removal methods, safety, and efficacy have been published in the dermatology literature.
R. Rox Anderson and Melanie Grossman discovered that it was possible to selectively target a specific chromophore with a laser to partially damage basal stem cells inside the hair follicles. This method proved to be successful, and was first applied in 1996. In 1997, the United States Food and Drug Administration approved this tactic of hair removal. As this technology continued to be researched, laser hair removal became more effective and efficient; thus, it is now a common method in removing hair for long periods of time.
Procedure
The primary principle behind laser hair removal is selective photothermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue.

Why this record matters
“Laser hair removal” is worth following because a concise public description often conceals a longer documentary argument. Here, Laser, hair and removal provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q783007. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995, 1996, 1998 and 1997.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
