Hair Loss and "Ozempic Face" on a GLP-1: What Causes Them and What Helps

Hair loss and “Ozempic face” on a GLP-1 usually aren’t caused by the drug itself. Both come from losing weight quickly, and both happen with any rapid weight loss. Hair shedding is usually temporary. Keeping your protein up, protecting muscle and not losing faster than you need to help with both.

Hair loss

Seeing more hair in the shower a few months into treatment is common. Rapid weight loss is a stress on the body, and it can push many hairs into their resting phase at once; they shed together a few months later. This is called telogen effluvium. It’s usually temporary, and the hair grows back. Low protein and gaps in nutrients make it worse, which is one more reason to keep protein up while your appetite is small (see protein and muscle on a GLP-1). If shedding is heavy, lasts more than several months or comes with patchy loss, see your doctor, since thyroid problems and low iron can cause it too.

“Ozempic face”

“Ozempic face” describes a face that looks thinner, older or looser after weight loss. It isn’t caused by the drug. It’s caused by fat loss in the face, and it’s most noticeable when weight comes off fast, before the skin has time to adapt. It happens with any rapid weight loss, with or without medication.

What helps with both

• Don’t lose faster than you need to. Faster isn’t better. A dose that erases your appetite can be lowered.
• Eat enough protein, about 1.2 to 1.6 grams per kilogram of body weight a day while you’re losing.
• Strength train to keep muscle, which shapes how you look as the weight comes off.
