Semaglutides such as Ozempic and Wegovy have changed the way millions manage their weight, but for many women, it’s come with an unexpected side effect: hair shedding.
While dermatologists say the culprit isn’t the medication itself, the rapid weight loss and lower nutrient intake that often follow can stress your hair cycle, pushing more strands into the shedding phase.
The good news: With the right nutrition and targeted supplementation, it’s possible to nourish follicles back to strength. Below, we’ve rounded up the five best hair supplements to help support healthy hair.

Routine Wellness Hair Supplement is made from ingredients that have been clinically shown to regrow hair. Simply put, they were my favorite supplements for hair growth if you’re on semaglutides.
The reason this supplement is so effective is twofold. First, the specific form of biotin they use is patented and is clinically shown to support hair growth in as few as 3 weeks. The reason this biotin works so well is because it is 40X more more soluble than traditional D-biotin (Vitamin B8), so your body is able to absorb it better. This provides your hair with a fuller and thicker look. In addition, this biotin is shown to reduce facial wrinkles and fine lines among women. Second, the supplement contains eggshell membranes that have been shown to have a significant impact on hair thickness and reduce breakage.
I was really happy to find a product that was geared towards women suffering from thinning hair. Almost everything I see on the market is just for men, so its great to see products that acknowledge women can also suffer from hair loss. Routine Wellness has thousands of reviews from insanely happy women, and many customers have had some incredible results.
Due to its effectiveness. clinically-tested ingredients, and ingredient profile, this was my favorite hair supplement if you’re on a semaglutide.

2. Natures Bounty Hair Gummies

A classic that’s stood the test of time, Nature’s Bounty Hair, Skin & Nails is a solid starting point for anyone noticing mild hair shedding. With biotin, vitamin C, and vitamin E, these gummies support keratin production and antioxidant protection — all in a sweet, berry-flavored chew that’s easy to stick with.
If your appetite has dropped and your overall vitamin intake has fallen, this affordable supplement helps fill basic nutritional gaps.

A long-time favorite, Viviscal uses its signature AminoMar marine complex — a protein blend that nourishes existing hair and encourages new growth. It’s been clinically studied for promoting thicker, fuller hair, and worth a try

Sometimes simple really is best. Amazon Elements Biotin delivers a straightforward 5,000 mcg dose of biotin — the most studied B-vitamin for hair and nail support. For women whose semaglutide routine has reduced their food intake (and possibly their biotin intake), this no-frills capsule helps support keratin production from within. To be clear, this isn’t the patented form of biotin that is super soluble, which is why it was ranked #4 on our list.

If semaglutide has lowered your appetite, you may not be eating enough protein — and hair health suffers fast when protein is low. Adding a scoop of collagen peptides to your coffee or smoothie helps replenish amino acids that support strong, elastic hair (and glowing skin as a bonus).
Remember, each person will have different experiences with these products and our tests weren’t scientific – these are just our opinions. We recommend you stick to something for at least 6 months to see if you are responding well to it.
