GLP-1 hair loss: which labels actually list it
Whether hair loss is on a GLP-1's label depends on the drug, and this page answers it for all 13 labels stored here, with the date on each. Most pages answer only the clinical half: shedding follows rapid weight loss from any cause, and it grows back. That is probably true, and it is not what someone typing a brand name is asking.
Do GLP-1s cause hair loss?
It is printed on 3 of the 13 labels: Foundayo and Wegovy and Zepbound. On the other 10 the words do not appear.
The split is not by molecule, which is the part nobody prints. Tirzepatide lists hair loss as Zepbound and does not list it as Mounjaro — the same molecule from the same maker, on labels published on the same day. A page telling you this drug causes hair loss and a page telling you it does not can both be quoting a current FDA label. They are quoting different ones.
What that does not settle is why, and the labels do not say. The obesity labels carry longer lists of common reactions in general, so part of this is a reporting threshold rather than a different effect — but nothing on the page distinguishes the two, so neither does this one.

Every label, and what it records
Sorted by molecule so the pairs sit together. The count is how many common adverse reactions that label lists in total, which is the context the yes or no sits in.

Hair loss, answered from the labels
- Do GLP-1s cause hair loss?
- On 3 of the 13 FDA labels this site reads, hair loss is printed among the common adverse reactions: Foundayo and Wegovy and Zepbound. On the other 10 it is not there at all. That is a statement about what each label records, which is the only thing a label settles. It is not a statement that the other drugs never do it, and no label says that either.
- Does Ozempic cause hair loss?
- The Ozempic label does not list it — and that label, published 2026-06-10, is older than Wegovy's, published 2026-06-30, which does. Both are semaglutide, from the same maker. So a page telling you semaglutide causes hair loss and a page telling you it does not can both be quoting a current FDA label, and they are quoting different ones.
- Why would the same molecule be listed differently?
- The labels do not say, and this page will not invent a reason. What can be measured is that the obesity labels carry longer lists of common reactions in general — Foundayo lists 13, Wegovy lists 17, Zepbound lists 12, against Ozempic at 5 and Rybelsus at 6 and Wegovy pill at 10 and Mounjaro at 7. A longer list can come from a lower reporting threshold or a longer trial rather than a different drug effect, and nothing on the label distinguishes those.
- Is GLP-1 hair loss reversible?
- No label here describes it as permanent, and none of them describes a course for it at all — the entry is a line in a table of common reactions, with no duration and no management. The course comes from dermatology instead: the American Academy of Dermatology lists losing 20 pounds or more among the common triggers of excessive shedding, and says that as the body readjusts the shedding stops and the hair tends to regain its normal fullness within six to nine months — unless whatever set it off continues.
- How do you stop hair from falling out on Ozempic?
- No label here says, and no trial has tested a way. The American Academy of Dermatology names two things that cause hair loss on their own and can be checked: too little biotin, iron, protein or zinc, and too much vitamin A or selenium — a deficiency is something a blood test can find. Biotin is the supplement usually suggested, and the NIH Office of Dietary Supplements says only case reports, all in children, support it for hair. The same fact sheet records FDA's report of a patient taking high-dose biotin who died after a troponin test, used to diagnose a heart attack, read falsely low — which is why a lab needs to know about it.
- Does a lower dose avoid it?
- Nothing on any of these labels ties hair loss to the dose. Where a reaction does track the schedule the labels usually say so — Wegovy's altered skin sensation is recorded as mostly at 7.2 mg, and hair loss carries no such note on either label that lists it.
