April 2026 in “Science Progress” This systematic review evaluates the association between glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and hair loss, identifying semaglutide and tirzepatide as having the highest incidence rates. Among the 24 studies included, androgenetic alopecia and telogen effluvium were the most reported subtypes, with tirzepatide frequently linked to telogen effluvium due to significant weight loss. Semaglutide's hair loss risk appears dose-dependent, affecting females more. Rapid weight loss is a potential contributor to telogen effluvium. Other GLP-1 RAs like liraglutide and dulaglutide showed lower risks. The review highlights the need for further research to understand the mechanisms, identify at-risk populations, and confirm causality through large-scale trials.
