September 2025 in “Dermatology and Therapy” This review suggests that glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have potential benefits for dermatologic conditions but may also cause adverse skin reactions and impact surgical outcomes.
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.
June 2026 in “Annals of Clinical Pathology” This review discusses how glucagon-like peptide-1 receptor agonists, used for type 2 diabetes and obesity, may cause skin aging and hair loss, and explores methylene blue as a potential protective treatment.
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.
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.
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.
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.
September 2025 in “Cureus” This systematic review found conflicting evidence on hair loss related to GLP-1 receptor agonists in adults with type 2 diabetes or obesity, with some studies noting hair regrowth and others reporting hair loss as a side effect. Further research is needed to understand this relationship.
This review highlights concerns about dermatological side effects linked to rapid weight loss from glucagon-like peptide-1 receptor agonists used for type 2 diabetes and obesity treatment, such as skin laxity, decreased collagen, and hair loss, emphasizing the importance of managing these while retaining metabolic benefits.
August 2024 in “Nutrition Bulletin” This editorial examines how GLP-1 receptor agonists, providing significant weight loss and cardiovascular benefits, can be integrated into a comprehensive obesity treatment alongside diet and lifestyle changes, but highlights the need for further guidance on their real-world application and multidisciplinary care.
June 2026 in “Frontiers in Nutrition” This study provides a narrative review suggesting GLP-1 receptor agonists could optimize metabolic health before conception in women with PCOS, but not necessarily improve fertility outcomes, emphasizing individualized use and the need for further research to confirm their reproductive benefits and safety.
May 2026 in “Dermatologic Surgery” This study reports conflicting evidence on whether GLP-1 receptor agonists are associated with various forms of alopecia, suggesting dermatology practitioners should consider monitoring and counseling patients using these medications.
May 2026 in “Open Access CRIS of the University of Bern” This narrative review explores current evidence on GLP-1 receptor agonists and hair-related conditions, noting reports of both hair regrowth and potential associations with telogen effluvium.
October 2025 in “International Journal of Dermatology” This review suggests weak associations between GLP-1 receptor agonists and increased reports of hair loss, particularly with semaglutide and tirzepatide, while cases of hair regrowth were also occasionally documented.
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.
September 2025 in “Cureus” This review suggests that GLP-1 receptor agonists may improve various dermatologic conditions, but larger studies are needed to confirm these findings.
This review indicates that glucagon-like peptide-1 receptor agonists may be linked to hair loss, raising safety concerns despite the lack of definitive causal evidence.

August 2024 in “Cureus” In this study, GLP-1 receptor agonists reduced BMI and improved metabolic and reproductive outcomes in women with PCOS, though the long-term effects remain unclear.
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.
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.
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.
June 2026 in “Quality in Sport” This narrative review found that combined oral contraceptives remain the primary treatment for hirsutism and acne in women with PCOS, but highlighted the need for further research to refine therapeutic options given the variable efficacy and emerging treatments like GLP-1 receptor agonists.
This study observed that methylene blue, a mitochondrial-targeted antioxidant, promotes hair follicle stem cell proliferation and viability through reduced oxidative stress and enhanced β-catenin signaling, and it may also protect against hair loss related to glucagon-like peptide-1 receptor agonists by reducing metabolic stress.
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.
February 2025 in “Journal of Neonatal Surgery” This study explores the role of antidiabetic medications, particularly metformin, GLP-1 receptor agonists, and DPP-4 inhibitors, in managing PCOS, highlighting their combination with hormonal therapies and lifestyle interventions for a comprehensive treatment approach.
