May 2026 in “Open Access CRIS of the University of Bern” Glucagon-like peptide-1 receptor agonists (GLP-1RAs), used for type II diabetes and obesity, have shown mixed effects on hair conditions. While some studies report hair regrowth in androgenetic alopecia and reduced inflammation in cicatricial alopecia, others associate GLP-1RAs with telogen effluvium. Due to varied findings, careful clinical evaluation and monitoring are advised. Further controlled studies are needed to understand GLP-1RAs' impact on hair biology and ensure safe use without discontinuing beneficial treatments.

March 2006 in “Regulatory Peptides” Mice skin has components that could help with hair growth and might be used for diabetes treatment.
November 2024 in “Circulation” GLP1-RAs may have higher reports of suicide and hair loss, but no strong evidence links them to these issues.
June 2026 in “Dermatology and Therapy” Glucagon-like peptide 1 receptor agonists (GLP-1RAs), used for type 2 diabetes and weight loss, have been linked to hair loss, particularly with semaglutide and tirzepatide, though causality is not established. Evidence primarily comes from pharmacovigilance databases and retrospective studies, with no prospective, controlled studies specifically addressing this issue. Rapid weight loss from these drugs may cause telogen effluvium, a potential mechanism for hair loss. As prescriptions rise in Europe, cases may increase, necessitating further research into causality and risk factors. Clinicians should inform and monitor patients for potential hair loss.
