We’re sharing easy nutrient secrets that keep follicles well-fed even when you’re eating less
Key Takeaways
- Ozempic and GLP-1s don't directly harm hair—but rapid weight loss can
- Getting enough protein and iron daily can help prevent GLP-1-related hair thinning
- Hair loss from weight loss is usually temporary, with regrowth in about 3 to 6 months
Does Ozempic cause hair loss? It’s a question many women are asking as GLP-1 medications like Ozempic, Wegovy, Mounjaro and Zepbound become household names. For those of us over 50 and already seeing extra strands in the shower drain, the concern feels even more serious (especially after a Real Housewives regular Sophia Umansky said she practically went bald).
So we went to top experts for answers—and we discovered good news, along with very important cautions if you begin losing weight rapidly with or without GLP-1s. Keep scrolling for everything you need to know about protecting your hair health.
Why Ozempic gets blamed for hair loss—and keto dieters should pay attention
“GLP-1 medications themselves aren’t directly toxic to hair follicles,” says Dawn Queen, MD, a board-certified dermatologist and hair loss specialist at Park Avenue Dermatology in New York City. If you use the medications as part of an overall health lifestyle, your hair shouldn’t be impacted at all. Woot!

But reports of hair loss while people are taking Ozempic aren’t made up. Turns out, any form of rapid weight loss—whether it’s due to GLP-1s, weight loss surgery, even an all-natural keto or low-cal plan—can lead to excess shedding. Meaning hair loss isn’t actually a side effect of Ozempic, but speedy weight loss itself.
“Most women experiencing increased shedding after rapid weight loss are dealing with a temporary condition called telogen effluvium, where a larger percentage of hairs shift into the shedding phase,” Dr. Queen explains. “Hair is a ‘non-essential’ tissue, so when the body is under stress or under-fueled, it diverts resources away from hair growth first.” The result: You may experience hair loss or hair thinning.
Taking measures to cover your nutritional bases and reduce weight-loss-related stress can prevent the issue. And if you’re already experiencing hair loss, you can rest assured it will most likely grow back. “Generally, hair loss due to rapid weight loss is not permanent and is fully reversible,” says Farhan Abdullah, DO, a board-certified internist, hormone expert and UT Southwestern professor.
How to prevent hair loss if you’re on Ozempic
Whether you’re taking a GLP-1 or losing weight through diet and exercise, these smart tips can help correct nutritional deficiencies and support healthy new hair growth.
Boost your protein intake
The single most important strategy for preventing hair loss while on Ozempic or during weight loss is maintaining adequate protein intake. “Hair follicles need amino acids to grow hair, and dietary protein is the best source,” says Dr. Abdullah. “Ensuring these are present in your body through diet can greatly alleviate hair loss issues.”
How much protein do you need? Research on bariatric surgery patients—who often experience extremely rapid weight—suggests that getting one gram of protein for every two pounds of ideal body weight daily helps protect muscle as well as hair and other body tissue. So if your optimal weight is about 160 pounds, you want to be sure you get at least 80 grams of protein from your food. If your appetite is so low you struggle to get this amount from sources like cottage cheese, beans and meat, Dr. Abdullah suggests using a protein shake to make up the difference.
Consider an iron supplement
When we eat less, it’s easy to skimp on key nutrients. “I’ve seen GLP-1s really reduce iron levels in some patients, and low iron can be a huge driver for hair loss,” says Aaron Erez, DO, a board-certified family medicine physician and functional medicine practitioner.
You can have your doctor test your levels. Or consider donating blood for a free test. A 2024 study found that telogen effluvium sufferers put on an iron supplement reported significant improvement and increased satisfaction with their hair in three months.
Dr. Erez recommends heme iron supplements, which are “much better tolerated and better absorbed.” As always, get your doctor’s okay before trying any new supplement.
Also important: From vitamins B and D to zinc, being deficient in any number of vitamins and minerals can cause or worsen hair shedding. So when your appetite is low, eat nutrient-dense options first—protein, produce and good fats—before you dig into any low-nutrient processed food or treats. “You want to aim for a healthy, balanced diet,” says Dr. Queen.
Try microdosing
If you’re on a GLP-1 medication like Ozempic, switching to smaller or less frequent doses reduces the odds of weight loss so rapid it triggers hair loss and other side effects. It can save a good bit of money too! “I personally utilize microdosing of GLP-1s in my practice so that weight loss is a slower process and less stressful on the body,” says Dr. Erez.
A new study in the journal Obesity suggests that patients on GLP-1 drugs such as Ozempic and Zepbound may be able to sustain weight loss and health improvements with fewer injections—instead of one every week, making them as infrequent as once every two months. While this approach may not suit every patient, it is something you can discuss with your doctor.
A happy ending for your hair
If you are reading this before you begin a GLP-1 or any weight-loss journey, you’re now armed with the know-how to keep your hair healthy the whole time. And if you’ve already experienced shedding, prepare for your hair to bounce back. “It takes anywhere between three to six months for the average woman to see hair regrowth,” says Dr. Abdullah. “Hair grows at a rate of half an inch per month.” Just make sure you’re fueling your body—and your strands—with the protein and nutrients they need to thrive.
