Does Biotin Help to Fight Hair Loss when taking Semaglutide? I've Tested Dozens of Biotin Vitamins and Gummies. - Here Are 5 That Actually Work in 2026
If you have experienced rapid weight loss, such as with semaglutide treatments, you’ll most likely experience hair issues like extreme shedding or heavy hair loss.
Over the last couple of months I saw a spike in clients experiencing these issues. Most of them were going through Semaglutide treatments.
While these drugs can be life-changing for many patients, one concern is showing up more frequently in the hair loss industry: Increased shedding and sudden hair thinning.
There is a difference between what the drug companies officially claim, and what trichologists are observing in real life.
Hair loss is not listed as a direct side effect in semaglutide. But many trials have reported that hair loss was a side effect of rapid weight loss.
This is backed by what trichologists and dermatology clinics are noticing:
Clients experiencing diffuse shedding 2–4 months after starting semaglutide.
This pattern is extremely consistent with a condition called telogen effluvium, a stress-induced
shedding response. A common condition I’ve already worked on with many clients.
In most cases it narrows down to increasing your nutritional support with targeted vitamin blends.
The product that my clients have seen the best results with were Biotin hair vitamin gummies. That’s why they have become my chosen professional recommendation.
Oral ingestion of a vitamin gummy allows for better absorption into the bloodstream, delivering essential vitamins and minerals directly to hair follicles. Speeding up natural recovery.
But with so many hair vitamin gummies brands out there, it wasn't easy for my clients to find the brands that really worked.
I've examined and tested many hair gummies (so you don't have to!), and would love to share with you my top 5 that actually helped me and my clients look visibly younger in 2026.
After testing multiple vitamins, WEEM was the clear standout above all, especially if you’re on GLP-1s.
WEEM addressed the thinning hair and shedding head-on with a high-absorption blend of 5000 mcg biotin, full-spectrum B-complex, and antioxidants like vitamins C and E to protect fragile follicles.
These nutrients are essential for healthy follicle function and new hair growth, without them, hair cells can’t regenerate properly, which is why so many women on GLP-1s experience unexpected hair loss
They're vegan, gut-friendly and were also very easy to take, even on an upset stomach. No pills to swallow, or chalky powders, just a delicious bunny shaped gummy that fits into my daily ritual.
Results came fast for me, many other users also reported less shedding and new baby hairs within 2 to 4 weeks without pausing their medication.
With 170,000 5 star reviews, and 4.6 rating, and verified by a certified specialist, WEEM stood out not just for its formula but for actually working when others didn’t.
WEEM is the gold standard for women seeking beauty support during and after GLP-1 weight loss.
#2 Nutrafol High-Potency, Doctor-Formulated… But Expensive
After comparing multiple formulas, Nutrafol ranked high for ingredient quality but came with a few trade-offs.
It’s packed with marine collagen, adaptogens, saw palmetto, and a full range of vitamins and minerals that target follicle strength, stress response, and scalp health.
That said, it’s positioned as a premium product. Although, at $88 a bottle, it’s significantly more expensive than others on this listts marine collagen base also makes it non-vegan, which may not suit all dietary needs. Some users noted the capsules were harder to take, particularly if they were already experiencing nausea from GLP-1 therapy.
Results were positive but often took longer with visible improvements typically showing after several months. And for those with sensitive stomachs or smaller budgets, consistency was more of a challenge.
For those seeking a high-potency formula and don't mind the price point, Nutrafol remains a strong choice. But for everyday ease and faster results, others like WEEM may be a better fit.
Viviscal earns points for its smart, nutrient-focused formula especially for GLP-1 users who may be low in iron or collagen.
It combines marine collagen with iron, zinc, and other essential vitamins that support hair structure and root-level growth. Iron, in particular, plays a vital role in oxygenating follicles, which is often overlooked in hair loss vitamins.
Since GLP-1s can impact iron absorption, Viviscal may offer meaningful support for women with thinning tied to both medication use and iron deficiency, a common but underdiagnosed combo.
The format is pill-based, and while generally well-tolerated, may not be ideal for those experiencing appetite suppression or queasiness. It’s also not vegan, due to marine-derived ingredients and animal-based additives.
Results came in slower and most users reported visible improvements around 8 to 12 weeks, which is a longer timeline compared to WEEM or Nutrafol. But for those with underlying iron-related hair loss, the targeted support can make a difference.
#3 Viviscal Iron and Collagen Power, But Too Slow
#4 Nature’s Bounty Gentle and Budget-Friendly, But Lower Impact
For early signs of shedding, Nature’s Bounty Hair, Skin & Nails offers an easy, affordable entry into hair support.
It includes core nutrients like biotin, B12, and vitamin D3, which contribute to overall hair health. While the doses are light and it lacks GLP-1-specific nutrients like zinc and folate, it may still benefit those with mild symptoms or sensitive systems.
Because it’s budget-friendly and widely available, it’s a practical option for easing in before upgrading to a more comprehensive formula.
Some users saw modest improvements in shedding with regular use. Just note, results tend to come slower, and the pill format may not suit those with GLP-1-related nausea or reduced appetite.
Overall, it’s a gentle first step, but for faster or more targeted results, a stronger formula may be needed down the line.
#5 Mary Ruth’s Clean, Natural, But Underpowered for GLP-1 Hair Loss
Mary Ruth’s Biotin Gummies are a favorite among wellness shoppers, thanks to their clean, plant-based formula and easy daily use.
They include biotin, zinc, B-vitamins, and a small dose of Fo-Ti, a traditional herb tied to hair support. It’s a gentle, non-toxic option that fits well into a routine especially for those just starting to address mild shedding.
Although, with 2500 mcg of biotin, it’s a significantly lighter-dose formula compared to options like WEEM, and it doesn’t include GLP-1–specific nutrients like folate, B12, or antioxidants. Some users reported stronger nails and light regrowth, though results typically appeared after 2 to 3 months.
For general wellness or early maintenance, it’s a solid pick. For faster, deeper support tied to GLP-1 use, a more targeted formula may be a better option.
