Hair loss is one of the most distressing — and underreported — side effects of GLP-1 medications like semaglutide (Wegovy, Ozempic) and tirzepatide (Mounjaro, Zepbound). Real-world research suggests it affects as many as 70% of GLP-1 users, roughly 10 times higher than the rates reported in clinical trials.
The good news: it is usually temporary, and in most cases it is caused by rapid weight loss triggering telogen effluvium — not a direct effect of the drug on your hair follicles. That means it is largely preventable and treatable.
This section covers everything you need to know: what causes GLP-1 hair loss, what the research actually shows, and the evidence-based strategies that genuinely help.
