Source — Semaglutide Hair Loss Mechanisms. Semaglutide (marketed for weight loss as Wegovy and for diabetes as Ozempic) is a GLP-1 receptor agonist that reduces appetite and supports significant weight loss, and is increasingly discussed in relation to Semaglutide Hair Loss. As use grows, many patients ask whether it can cause hair shedding or thinning. The short answer: hair loss has been reported with semaglutide in weight-loss trials, but it appears uncommon and is often linked to rapid weight loss (telogen effluvium) rather than a direct toxic effect on hair follicles.
