Does Wegovy cause hair loss?

Yes, and it is on the label rather than only in reports: hair loss appears among the common adverse reactions in Wegovy's FDA prescribing information, published 2026-06-30. Listed means it was seen often enough in the trials to be printed, not that it happens to everyone. Rapid weight loss pushes hair follicles into their resting phase at the same time, and they shed together a few months later. It is called telogen effluvium and it is a response to the speed of the loss rather than to the molecule — the same thing happens after surgery, illness or childbirth. It does not follow the dose schedule. The shed tends to start a few months after rapid weight loss begins, and it is self-limiting: the follicles are not damaged, and regrowth follows over the months after it. What helps first: time. The shed is self-limiting and follicles are not damaged; regrowth follows. It stops being ordinary at a specific line: patchy loss rather than a general thinning, or loss with a rash or scalp pain. That is a different problem and needs a look.

What helps with hair loss on Wegovy?

1Time. The shed is self-limiting and follicles are not damaged; regrowth follows.
2Enough protein and enough iron, both of which fall easily on a much smaller intake.
3Slowing the rate of loss if it can be slowed, which is the only lever that acts on the cause.

Nausea, diarrhea, vomiting and constipation are the reason most people stop. They are worst in the first days after each dose increase and usually settle; a schedule held longer at one step is the standard answer, and it is a conversation with the prescriber rather than a reason to quit unannounced.

When is hair loss on Wegovy serious?

Patchy loss rather than a general thinning, or loss with a rash or scalp pain. That is a different problem and needs a look.

Separately, Wegovy carries a boxed warning. In rodents this molecule caused thyroid C-cell tumors at human-relevant doses. Whether it does so in people is unknown, and the label carries that as a boxed warning. It is contraindicated outright with a personal or family history of medullary thyroid carcinoma or MEN 2.

Would switching drugs help?

Hair loss is on 3 of the 13 FDA labels tracked here; the other 3 products on the same molecule do not list it, which is a fact about the labels rather than a promise about any one person. What a switch does change is what you pay, and Wegovy is $349 a month at the maintenance dose here.
