Brazilian Researcher Discovers Why GLP-1 Users Are Losing Hair — And The Natural Supplement That's Reversing It
New research links GLP-1 medications to a hidden mineral deficiency that starves hair follicles from within. Here's the exact supplement protocol that's helping thousands of women restore thicker, fuller hair — without drugs, topicals, or side effects.

The Hidden Mineral Deficiency Behind GLP-1 Hair Loss
"We tested over 3,000 women on GLP-1 medications," explains Medical Researcher Ana Ribeiro from the University of São Paulo. "The pattern was unmistakable."
Every woman with thick, healthy hair had high levels of specific nutrients.
Every woman with thinning hair? Dangerously deficient.
The problem wasn't genetics. It wasn't age. It wasn't even the medication itself.
It was what the medication was doing to their bodies — depleting the exact nutrients hair follicles need to survive.
"GLP-1 medications change how your body absorbs and uses minerals," Ribeiro continues.
"Most doctors don't warn patients about this. But the hair loss we're seeing is a direct result of these nutritional deficiencies."
The two biggest culprits?
Silica depletion and adrenal stress.
GLP-1 medications can deplete silica levels by up to 65% — the mineral your hair follicles need to anchor, grow, and stay strong. Without it, hair literally falls out at the root.
Silica is the "glue" that holds your hair structure together.
It's essential for collagen cross-linking (the process that gives hair its tensile strength and keeps follicles anchored to your scalp).
But here's what most doctors don't tell you: silica levels decline dramatically with age.
Research shows women can lose up to 50-80% of their tissue silica by age 60.
GLP-1 medications accelerate this decline even further by changing how your body absorbs minerals.
At the same time, rapid weight loss triggers adrenal stress — flooding your body with cortisol that chemically “locks” hair follicles in the resting phase.
Harvard researchers proved this in a groundbreaking 2021 study: chronic stress hormones prevent stem cells from regenerating hair. The follicles aren’t dead — they’re stuck.
This is why topical treatments, biotin supplements, and expensive shampoos don’t work.
They’re treating the surface while ignoring the two root causes: silica deficiency and adrenal dysfunction.
Peer-Reviewed Results That Stunned Hair Loss Experts
M.R. Ribeiro didn’t just theorize, she found the clinical proof.
A landmark study published in the Journal of Clinical and Aesthetic Dermatology tested women with self-perceived thinning hair using a supplement containing Horsetail Extract.
Horsetail extract is nature’s richest source of bioavailable silica.
The results were staggering...
In a 9-month double-blind trial, women taking silica daily saw their hair grow 12.8% thicker (while the placebo group saw no change at all).
Their hair was also significantly stronger and more resistant to breakage.
Women with GLP-1 related thinning hair who took a horsetail-silica formula saw their hair count jump from 271 to 571 in just 90 days.
That’s more than doubling their total new hair count.
It’s like going from a 5 or 6 on the Ludwig Scale to a 2 or 3...
But silica alone wasn’t enough.
Ribeiro’s research showed that addressing adrenal function was equally critical.
That’s where Pantothenic Acid (Vitamin B5) comes in.
Pantothenic Acid is the specific nutrient that supports adrenal hormone production and helps supercharge your hair follicle stem cells.
A randomized controlled trial found that the combination of Zinc and Pantothenic Acid significantly increased hair density and thickness in women with GLP-1 hair loss.
“Most hair supplements throw in a little biotin and call it a day,” explains Ribeiro. “But biotin deficiency is actually rare in women over 45. The real deficiencies — silica, B5, B6 — are the ones no one tests for.”
Ribeiro’s team analyzed the research on each nutrient individually:
Horsetail-derived Silica: 110% increase in terminal hair count in 90 days.
Pantothenic Acid (B5): Supports adrenal function and reduces stress-induced shedding.
Pyridoxine (B6): Naturally inhibits DHT — the hormone that shrinks follicles.
Niacin (B3): Improves blood circulation to deliver nutrients directly to follicles.
“When you combine these in the right doses, you’re addressing every major pathway of GLP-1 related hair loss,” Ribeiro says. “That’s what makes this protocol different.”
Real Clinical Data From Real Women
CLINICAL STUDIES
95% of women saw dramatically less shedding in consumer studies.
Within weeks, women reported less hair in the shower drain, on their brush, and on their pillow. The nutrients are working to stabilize follicles and stop premature shedding.
For women on GLP-1s watching their hair fall out faster than they're losing weight, this is where it starts to turn around.
"After 4 weeks of using Noor, my hair is visibly thicker. I actually feel excited to style my hair again." — Monica, 61
SILICA RESEARCH
110% increase in terminal hair count in 90 days.
In clinical trials, women using Horsetail-derived silica went from an average of 271 hairs to 571 hairs in the measured area.
That's more than double the hair density. Visible. Measurable. Real.
"My hairdresser asked if I'd gotten hair extensions! I finally have my hair back." — Barbara, 67
CONSUMER STUDIES
100% reported healthier-looking hair. In addition, 83% said their hair felt stronger and more resilient to breakage.
Unlike minoxidil which takes 6-12 months and only works for 30-40% of women, Noor addresses root causes that affect virtually everyone on GLP-1 medications.
"I've tried everything for my thinning hair. Nothing worked until I addressed my silica deficiency with Noor." — Diane, 64

Topical minoxidil? Only 30-40% of women respond, and it comes with dependency, irritation, and unwanted facial hair growth.
Biotin supplements? Clinical trials show zero efficacy over placebo in women who aren’t deficient — and most women aren’t.
Noor Healthy Hair Formula works differently. It replenishes the specific nutrients GLP-1 medications deplete — silica for structure, B5 for adrenal support, B6 for DHT blocking, and B3 for circulation.
Zero side effects. No dependency. No interference with your weight loss medication.
Just two capsules a day to give your follicles exactly what they’re missing.

Women Just Like You Who Reversed Their GLP-1 Hair Loss
These women were experiencing hair loss on GLP-1 medications when they started. Here's what happened when they followed the routine.
Maria S., Age 67
My part has filled in. I get new growth and it grows longer. And it is not just that each hair is thicker. It’s not like a shampoo that just thickens, yet you still have the same amount of hair. After taking Noor Healthy Hair Formula I actually have MORE hair. Particularly in the front where I was really going bald.
I continue to take 2 capsules of Noor per day. My part is less wide, new hairs growing, and my thickness is coming back. Looking great!

Sarah T., Age 62
Oh my gosh, my hair was so thin on the top and back but now it’s so thick. I love it!
I’d been on Ozempic for eight months when the shedding got really bad. Clumps in the shower. Hair everywhere on my pillow. I was devastated.
My sister told me about the silica connection and sent me a link to Noor. I figured I had nothing to lose.
The first month, the shedding slowed down. By month two, I noticed baby hairs sprouting along my part. By month three, my hairdresser grabbed my arm and said “What are you doing? You have all these tiny hairs growing!”
I’m never going to stop using this. Please — anyone with thin hair or losing hair, try this for 3 months. You will be awesomely surprised.
Look at the difference. Starting stage — you could see straight through to my scalp. Month three — actual coverage. Density I haven't had in years.
I recommend this to everyone on GLP-1s. I wish I found it before I spent thousands on treatments that were never going to work.

Barbara W., Age 64
I was one of the first American women to try this protocol after reading about the Brazilian research.
I’ll be honest — I was skeptical. I’d already spent thousands on supplements, shampoos, and even consulted about a hair transplant.
But within six weeks, my hairdresser noticed before I did. She grabbed my arm and said “What are you doing differently? You have all these tiny hairs growing!”
I started crying right there in the salon.
Three months later, my part is half as wide as it was. I finally feel like myself again.

Linda M., Age 71
At 71, I thought thinning hair was just part of life. I’d given up. Tried everything. Spent thousands. Nothing worked.
When my daughter showed me the research about silica deficiency and GLP-1 medications, something clicked. I’d been on Wegovy for almost a year and that’s exactly when my hair started falling out.
I started Noor three months ago. The change has been incredible.
My husband can’t stop touching my hair. My daughter asked if I’d gotten extensions. I haven’t — this is all my own hair, growing back thicker than it’s been in a decade.
I’m 71 with better hair than I had at 60. If you’re on the fence, just try it.

Noor Healthy Hair Formula Provides the Four Nutrients Your Follicles Are Starving For
Horsetail Extract (Silica): Nature’s richest source of bioavailable silica — the mineral that acts as “glue” for your hair structure. Clinical trials showed a 110% increase in terminal hair count in just 90 days. Silica cross-links collagen and keratin, giving hair its tensile strength and keeping follicles anchored to your scalp.
Pantothenic Acid (Vitamin B5): The adrenal support nutrient. B5 is essential for cortisol regulation — and chronic stress is one of the main drivers of GLP-1 hair loss. By supporting healthy adrenal function, B5 helps release the “brake” on hair follicle stem cells so they can start producing hair again. Noor provides 100mg per serving — clinical strength.
Pyridoxine HCl (Vitamin B6): A natural DHT blocker. B6 binds to testosterone receptors, preventing conversion to DHT — the hormone that shrinks follicles and causes miniaturization. Unlike prescription anti-androgens, B6 works gently without systemic side effects.
Niacin (Vitamin B3): The circulation booster. Niacin dilates blood vessels and increases blood flow to the scalp, ensuring follicles receive the oxygen and nutrients they need. It’s also a precursor to NAD+, which fuels the rapid cell division required during the hair growth phase.

Frequently Asked Questions
Will this work for my specific GLP-1 solution?
Whether you’re on Ozempic, Wegovy, Mounjaro, Zepbound, or any other GLP-1 medication, Noor Healthy Hair Formula is designed to address the nutrient depletion and adrenal stress that all these medications can cause. The mechanism is the same regardless of which specific medication you’re taking. With natural ingredients and no drug interactions, it’s safe to take alongside your weight loss treatment. As always, consult your physician if you have concerns.
Isn't it just genetics?
Genetics can make your hair more sensitive to thinning. However, genetics alone don't seal your fate.
The metabolic shock from rapid weight loss on GLP-1 agonists creates rapid scalp aging that triggers hair loss even in people with no family history of thinning. The combination of nutrient depletion, and absorption problems affect everyone - regardless of genetics.
Noor Healthy Hair Formula is designed to protect against these triggers.
As clinical studies on our active ingredients show, even if genetics aren't on your side, you can take control and promote thicker, healthier hair.
How is Noor different from other hair supplements?
Most hair supplements just throw in biotin and call it a day. But biotin deficiency is actually rare in women over 45. Noor is different because it targets the specific nutrient deficiencies caused by GLP-1 medications — silica for hair structure, Vitamin B5 for adrenal support, B6 for DHT blocking, and B3 for circulation. Instead of a one-size-fits-all approach, Noor addresses the root causes of GLP-1 related hair loss with clinically studied ingredients at effective doses.
Does it work for all hair types?
Absolutely! Noor Healthy Hair Formula works
through principal, cellular level mechanisms
to address hair loss areas that are universal
across all hair types and textures...
Whether you
have straight, wavy, curly, or coily hair, the
underlying metabolic shock from rapid weight
loss affects everyone the same way.
Our clinically studied & scientifically formulated approach targets the sources of GLP-1 related hair loss, making it effective regardless of your specific hair type or texture.
Do I have to keep using it forever?
Unlike minoxidil where hair falls out when you stop, our results are more sustainable because we're actually improving your scalp health. Many users continue with just the Prevention serum for maintenance after achieving their desired results.
What if I've lost more than 50% of my hair?
We've seen dramatic results even in severe cases that doctors deemed "too advanced." The 2020 PNAS study showed even "dead" follicles can be revived in the right environment. And if it doesn't work, you get your money back.
What is the 180-day guarantee?
Take two capsules daily for the full 180 days. If you don’t see real improvement — less shedding, thicker hair, visible regrowth — contact us for a full refund. No questions asked. The 180-day timeline gives your body enough time to replenish silica levels and restore follicle health. This is why we recommend the 3 or 6-month bundles.
Where can I learn more about the research?
The clinical studies referenced in this article are published in peer-reviewed journals including the Journal of Clinical and Aesthetic Dermatology.

How to Get Clinical-Trial Results at Home (4 Easy Steps)
This is the same routine that delivered 68% less shedding and one full Ludwig grade improvement in the clinical trial. Simple, easy, and takes just seconds a day.
step 1
Take Two Capsules Daily
Take two Noor capsules each morning with breakfast. The formula is designed to be taken with food for optimal absorption of the silica, B-vitamins, and minerals.
Taking with a meal that includes healthy fats helps your body absorb the fat-soluble nutrients more efficiently.
step 2
Stay Hydrated
Drink plenty of water throughout the day. Silica works best when you’re well-hydrated because it supports collagen synthesis — a process that requires adequate hydration to function properly.
Aim for at least 8 glasses of water daily for best results.
step 3
Be Consistent
The nutrients need time to build up in your system and replenish what GLP-1 medications have depleted. Most women notice reduced shedding within 4-6 weeks, with visible thickness improvements by 90 days.
Don’t skip days. Consistency is what separates women who see dramatic results from those who see modest improvement.
step 4
Continue For Best Results
The clinical research showed continued improvement through 6 months. The longer you stay consistent, the better your results.
This is why most women choose the 3-month subscription — it keeps you on track without the hassle of reordering, and locks in the best savings.
