This study found that GLP-1 receptor agonists are linked to a 40% increased risk of non-scarring alopecia in adults, mainly due to weight loss-induced micronutrient deficiencies, with semaglutide and tirzepatide showing the highest hair loss signals.
July 2026 in “Journal of the American Academy of Dermatology” GLP-1 and GLP-1/GIP agonists may increase the risk of hair loss.
This study found that GLP-1 receptor agonists are linked to a significant 40% increased risk of non-scarring alopecia, which may result from weight loss-induced micronutrient deficiency.
June 2026 in “Skin Appendage Disorders” This meta-analysis found that GLP-1 receptor agonists are associated with a 40% increased risk of non-scarring alopecia, likely due to weight loss-induced micronutrient deficiency, with significant associations for telogen effluvium and androgenetic alopecia. However, some patients with central centrifugal cicatricial alopecia showed improvement.
October 2025 in “JEADV Clinical Practice” This study found that patients using GLP-1 receptor agonists, specifically liraglutide, dulaglutide, and semaglutide, had a higher likelihood of being diagnosed with androgenetic alopecia, while those on exenatide showed increased odds for both androgenetic alopecia and telogen effluvium.
