Study Links Popular Weight-Loss Drugs to Increased Male Hair Loss
Researchers found a 7% added hair-loss risk in men already genetically prone to androgenetic alopecia after GLP-1 drug use, the study said.
On Thursday, NYU Langone Health researchers published a study in the Journal of Investigative Dermatology linking GLP-1 medications like Ozempic to a 7 percent added risk of hair loss in men genetically predisposed to androgenetic alopecia.
Prescriptions for these medications have more than tripled since 2020, with patients often attributing hair thinning to rapid weight loss, though researchers now suggest a biological mechanism beyond weight loss alone.
The team analyzed genetic data from more than 31,000 men and women and more than 205,000 men, adjusting for hypertension, insulin resistance, and lowered testosterone; the 7 percent risk remained constant across all adjustments.
Senior investigator Lynn Petukhova suggested that if future experiments succeed, "some men, and possibly women too, could be screened and benchmarked for their risk" before receiving prescriptions; current prescribing guidance has not changed.
Petukhova plans to investigate whether these genetic links apply to women; the study was funded by National Institutes of Health grants, and investigators disclose paid consulting relationships with Pfizer, Lilly, Ro, Priovant, Veradermics, and Aquis.
