GLP-1 & your hair · Evidence Review
Losing your hair on Ozempic or Wegovy? Here's what actually helps.
A certified scalp specialist on why Ozempic, Wegovy and Zepbound trigger shedding, and a plain review of the five supplements worth considering.
The short version
- The shots don't attack hair directly. Rapid weight loss and eating less starve the follicle, and it sheds two to three months later.
- It won't stop on its own, but it's usually temporary, and you don't have to quit the shots to turn it around.
- Of the five reviewed, WEEM was the most complete and the best value for getting through it.
You did the hard thing, and the weight came off. Then, a couple of months in, the shedding started: more hair in the shower drain, a thinner ponytail, more scalp in the mirror. It is easy to fear the drug is ruining your hair, but that is not what is happening.
Why it happens
Doctors call it telogen effluvium, the same shedding people see after surgery or a crash diet. None of it is the drug poisoning your hair, and none of it is your shampoo. The follicle is starved, not damaged, so the fix is internal: eat more protein than feels natural, lose the weight a little slower if you can, and refill the vitamins and minerals that drop when you eat less. That last part is where a supplement earns its place, not a mega-dose of biotin on its own, but the full blend working together, taken every day. And the hair you have now is the most you will ever have to work with, so waiting only loses ground. You do not have to quit the shots to turn this around.

The five, ranked
Built around the whole nutrient picture, not a single headline ingredient, and easy to keep down when your appetite is all but gone.
- A complete blend: biotin with Vitamins A, C and E, a full B group, and zinc, the nutrients that run short when you eat less
- Just two gummies a day, no fish, no gelatin, no horse-pill to force down on an empty stomach
- Less shedding within a couple of weeks, fuller, thicker-looking hair by around 90 days
- A premium formula at around a quarter of what the big names charge, backed by a money-back guarantee
- Sold online only, not on store shelves
WEEM is currently giving a free Starter Pack with first orders, over $45 in additional value. It's a limited time offer, so I'd order now while it's still available.

One of the better known names. It's built more around stress botanicals than the nutrient gap that opens when you eat less, and it's the priciest here by some way.
- Includes adaptogens like ashwagandha
- Contains antioxidants and collagen peptides
- Around $88, nearly four times the price, and four capsules a day
- Fish based, so not for vegans
A long established brand with a loyal following. Built around iron, which is a different gap to the one described here, and it tends to take a while to show.
- Built around its marine protein complex
- Contains iron and collagen
- Two tablets with food, and slower to show than the others
- Fish and shark based, not for vegans
The drugstore standby. Fine for basic biotin, but it wasn't built for this kind of shedding.
- Easy to find almost anywhere
- A little B12 and vitamin D
- Mostly biotin on its own, without the zinc and full blend hair is built from
- Made with gelatin, not vegan
A vegan gummy from a popular wellness brand. A gentle, lower dose choice for someone who only wants a light biotin top-up.
- Has B vitamins and zinc
- A touch of Fo-Ti, a traditional herb
- A lower dose, around 2,500 mcg of biotin
- Didn't match WEEM's results in our testing
Keep the weight off, and keep your hair
The shedding doesn't wait, and every week underfed is more hair to grow back later. Of everything tested, WEEM was the most complete, the easiest to take when you're barely eating, and the best value to stay on for the full ninety days.

Weight-loss shedding (telogen effluvium) usually eases as your weight steadies and your eating evens out; shedding that continues past about six months is worth checking with your doctor.
