Do GLP-1 weight-loss medicines cause hair loss?
Why some people notice hair shedding on Wegovy or Mounjaro, and whether it lasts.
Hair loss is reported by some people taking GLP-1 medicines. It's usually linked to telogen effluvium, temporary shedding triggered when the body is under stress, for example from rapid weight loss, eating much less, or changes in nutrients, rather than a direct effect of the drug.
Shedding like this is often temporary and improves as the body adapts. Eating enough protein and a varied diet can help. If hair loss is severe or doesn't improve, speak to your doctor.
