Hair loss on a GLP-1

Mounjaro’s and Wegovy’s leaflets list it as common, up to 1 in 10 people, and both NHS pages name it. Mounjaro’s lists it for people treated for weight management, and Wegovy’s says it may happen more often at 7.2mg. Zepbound’s label says hair loss in its trials was associated with weight reduction.

What else they say

  • More often in women

    In two Zepbound weight trials, one with type 2 diabetes, 7.1% of women on it reported hair loss, against 0.5% of men.

  • None stopped for it

    In those trials, the label says, nobody on Zepbound stopped treatment due to hair loss; one person on placebo did.

  • If it bothers you

    If a side effect bothers you or doesn’t go away, the NHS says a pharmacist or doctor may give advice on how to reduce it.

  • On stopping

    The NHS says keep taking your medicine unless you’re advised to stop, and talk to your doctor if you want to stop.

Questions

Does Ozempic cause hair loss?

Ozempic’s leaflet doesn’t list it. The NHS semaglutide page, which covers Ozempic and Wegovy, lists hair loss among semaglutide’s common side effects.

Is it linked to losing weight?

Zepbound’s label says hair loss in its trials was associated with weight reduction. Mounjaro’s leaflet lists it for people treated for weight management.

Will my hair grow back?

None of these sources says how long hair loss lasts. If it bothers you or doesn’t go away, the NHS says speak to a pharmacist or doctor.

Side effects

Count the days hair loss is there.

“Hair Loss” is one of the check-in’s side effect tags. Side Effects counts the days you felt each one, over 7, 30 or 90 days, ready for your next review.
