August 2026 in “The Laryngoscope” This study found that adults with type 2 diabetes or obesity using semaglutide and tirzepatide experienced higher odds of nonscarring alopecia, such as telogen effluvium, compared to those using other GLP-1 receptor agonists, with hair loss potentially linked to physiologic stress from weight loss.
August 2026 in “Revista Ibero-Americana de Humanidades, Ciências e Educação” This narrative review suggests that the association between weight-loss medications and telogen effluvium is primarily due to metabolic changes from rapid weight loss, rather than a direct pharmacological effect on hair follicles.
July 2026 in “Journal of Investigative Dermatology” GLP-1 therapies can cause hair loss, but hair often regrows after stopping or reducing the drug.
July 2026 in “Journal of the American Academy of Dermatology” GLP-1 and GLP-1/GIP agonists may increase the risk of hair loss.
June 2026 in “Dermatology and Therapy” In this commentary, the authors discuss emerging evidence primarily from pharmacovigilance data and retrospective studies indicating a potential association between GLP-1 receptor agonists, like semaglutide and tirzepatide, and hair loss, although causality remains unproven, prompting recommendations for patient monitoring and further research.
