Can semaglutide cause hair loss?

Hair loss is not one of semaglutide's most common side effects in studies. Those are mostly stomach and gut problems. But fast, large weight loss of any kind is a known trigger for a short-term shedding pattern called telogen effluvium. Whether that applies to someone on semaglutide is a personal medical question. This site's own studies for the drug do not report hair loss as a measured result.
