July 2026 in “Journal of the American Academy of Dermatology” GLP-1RA medications may increase the risk of hair loss, especially in non-diabetic people.
October 2025 in “EMJ Dermatology” This study found that glucagon-like peptide-1 receptor agonist therapy was independently associated with an increased incidence of non-scarring hair loss, including telogen effluvium and androgenic alopecia, in adults but not alopecia areata.
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.
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 “JAAD reviews.” This literature review highlights a potential but uncertain link between GLP-1 receptor agonist therapy for type 2 diabetes and obesity and hair loss, with variations among different medications.
