May 2003 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.
1 citations
,
July 2020 in “Dermatology” This review discusses the mechanisms, applications, and research evidence of photobiomodulation, highlighting its efficacy, safety, and potential for standardized evaluation methods, but reports no new clinical results.

September 1972 in “British Journal of Pharmacology” In this study on male rats, parachlorophenylalanine treatment induced hypersexual behavior and hair loss linked to increased social interaction but had no effect on brain serotonin when testosterone was used instead.
This study found that in-person photobiomodulation treatments improved hair growth in men and some women with androgenetic alopecia, except for the laser band and combination laser/LED helmet in women.
