Ozempic and Hair Loss: Is Weight the Only Thing You Lose?

If you're on Ozempic, Wegovy or Zepbound and your hair seems thinner, the usual explanation is the weight loss, not the drug. Two new lines of research complicate that answer. One is a September 2026 genetic study of about 205,000 men that found a modest link between GLP-1 receptor activity and patterned hair loss. The other is a pair of early, not-yet-peer-reviewed conference studies that found hair and nail changes reported more often among people taking these drugs. I break down what each study measured, what it can't tell us, why the weight-loss explanation may be incomplete, and what to bring up with your prescriber if you're noticing changes.
