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.

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.
May 2026 in “Pharmaceuticals” This study analyzed safety data for semaglutide, liraglutide, and tirzepatide from the EudraVigilance database, identifying potential safety signals not listed in current SmPCs, such as optic ischemic neuropathy and pancreatitis, underscoring the importance of ongoing pharmacovigilance.
April 2026 in “Science Progress” This study found that among users of glucagon-like peptide-1 receptor agonists, semaglutide and tirzepatide were associated with higher incidences of hair loss, particularly androgenetic alopecia and telogen effluvium, with rapid weight loss identified as a potential contributor to telogen effluvium.
October 2025 in “Brazilian Journal of Hair Health” This narrative review identifies telogen effluvium as a growing concern linked to weight-loss interventions, such as GLP-1 receptor agonists and bariatric surgery, attributing hair loss to systemic and metabolic stress rather than permanent hair follicle damage.
April 2026 in “Open MIND” This review article discusses the aesthetic impacts of GLP-1 medications like Ozempic (semaglutide), including "Ozempic Face," skin sagging, and loss of lean mass, and explores potential recovery methods such as biostimulators, HIFU, endolaser, and PRP.

July 2026 in “Preprints.org” In this observational study, researchers found that new users of tirzepatide experienced a higher incidence of alopecia compared to semaglutide users over a 12-month period, with increased risk persisting even when accounting for achieved weight loss and treatment duration.
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.

August 2025 This study found that GLP-1 receptor agonists show potential for improving psoriasis and hidradenitis suppurativa by reducing inflammation and lesion severity, but they also pose dermatological risks such as alopecia and injection site reactions.
August 2026 in “Journal of Cosmetic Dermatology” This study observed that dermatological and hair changes, like skin sagging and hair shedding, commonly occur early during weight loss with GLP-1 receptor agonists, highlighting the need for tailored dermatological care alongside treatment.
April 2026 in “Journal of Clinical Medicine” This review summarizes recent research into the effects of GLP-1 receptor agonists on skin processes, noting potential benefits for wound healing but also potential cosmetic concerns like facial fat loss and decreased collagen, highlighting the need for more clinical studies to clarify their dermatological impact.
