Frequently Asked Questions

Yes. And the evidence is now peer-reviewed, substantial, and undeniable:

• 3.4× increased risk — Meta-analysis of 24 clinical studies found women on GLP-1 medications are 3.4 times more likely to experience hair loss vs. placebo (Gupta et al., Science Progress, January 2026, P = 0.02)
• 6.97× for Ozempic/Wegovy specifically — University of Miami study found semaglutide users have nearly 7 times the hair loss risk of non-users (Burke et al., 2025)
• 14× higher risk for women — Women on Zepbound face 14 times the hair loss risk that men on the same medication face (Sodhi et al., 2025 & FDA prescribing data)
• 1,000+ FDA reports — Formal adverse event reports filed with the Food and Drug Administration (Rojas Lopez et al., Cureus, 2025)

It's in your medication's prescribing information. It's in multiple peer-reviewed journals. It's being discussed by dermatologists at specialist centers across the country. It's real, it's documented, and it's happening to approximately 1 in 4 women on these medications.

This is one of the most common and most frustrating experiences GLP-1 users describe. Your doctor isn't wrong — your results may genuinely fall within the standard lab reference ranges.

Here's the problem: standard lab reference ranges for ferritin (stored iron) consider anything above 12–20 ng/mL to be "normal." But hair specialists and trichologists consistently require ferritin above 70 ng/mL for adequate follicle function during active shedding.

There's a 50-point gap between "lab normal" and "hair normal." Women who have been eating significantly less for 3–6 months frequently land in the 20–40 ng/mL range — technically fine by lab standards, functionally insufficient for hair growth.

If your doctor says your bloodwork is fine but your hair is still falling out, ask them specifically about your ferritin level and request the actual number (not just "normal"). A number below 70 ng/mL is worth discussing.

This question perfectly captures the mechanism of telogen effluvium — the type of hair loss caused by GLP-1 medications.

Here's the timeline: From your first injection, your appetite is suppressed. You eat less. Gradually, your body's reserves of zinc, iron, and B12 begin to deplete. Simultaneously, your body perceives rapid weight loss as physiological stress and starts pushing hair follicles into their "resting" phase (telogen).

Here's the catch: there's a 60–90 day delay between when follicles enter the resting phase and when they shed. The follicle stress happens in months 1–2. The hair falls out in months 3–4.

This is why so many women describe it happening "right on schedule" at month 3, and why starting Alluvani before the shedding begins (or as early as possible) gives your follicles the best chance.

For some women, GLP-1 hair loss does stabilize on its own — typically when their body reaches a new nutritional equilibrium. However, clinical research has found something critical: unlike nausea (which typically improves over time), GLP-1-associated hair loss can continue to progress alongside treatment for some women.

Here's what happens if you wait too long: Prolonged, untreated telogen effluvium leads to hair shaft miniaturization — a real, documented phenomenon where the hairs that regrow become progressively thinner and finer. This is not cosmetic damage. This is biological change:

• Months 2–4 of untreated shedding: Optimal intervention window. Starting support here prevents miniaturization entirely.
• 4–6 months without support: Miniaturization begins. Regrowth starts coming in noticeably finer. Still recoverable, but harder.
• 6+ months of untreated shedding: Pronounced miniaturization. Hairs may permanently thin by 30-50%. Recovery takes much longer and may not fully restore pre-loss density.

This is not scare tactics. This is peer-reviewed mechanism. The longer telogen effluvium continues untreated, the more permanent the density change becomes. Dermatologists know this. That's why they recommend early intervention.

Additionally, for women over 45 who may have underlying androgenetic alopecia (AGA) accelerated by the GLP-1-induced telogen effluvium, waiting without nutritional support means the window for preventing permanent density loss gets smaller every month.

The sooner you address the nutritional depletion, the shorter the shedding window and the faster the recovery. Alluvani works best when started early — ideally within the first 2–3 months of shedding, before miniaturization begins. If you're already weeks into hair loss, that's still fine — but waiting longer significantly reduces your recovery options.

Yes — and this combination is more common than most people realize. Women in perimenopause or early menopause face a potential "double problem."

As estrogen declines, hair follicles become more sensitive to androgens. This creates a slow, gradual thinning (androgenetic alopecia, or AGA) that many women don't notice until a trigger event occurs. GLP-1-induced telogen effluvium is exactly that trigger: a mass shedding event that can reveal and accelerate the underlying AGA.

If you're 45–65 and on a GLP-1 medication, your hair may be experiencing two separate mechanisms simultaneously. Alluvani's formula includes saw palmetto to address the DHT component of the AGA mechanism, in addition to the nutritional support for GLP-1-induced TE.

Biotin alone: Biotin supports keratin synthesis — one of the six or seven nutritional inputs your follicles need. GLP-1 appetite suppression depletes the other five: zinc, iron (ferritin), B12, vitamin D, and the amino acids that build keratin. Taking biotin alone for GLP-1 hair loss is like fixing one tire on a car with four flats.

Nutrafol: Nutrafol is a quality product — designed for genetic and hormonal hair thinning in women who are eating normally. Their clinical trials did not involve GLP-1 users. Their formula targets DHT-driven androgenetic alopecia and general stress-related thinning. At $88/month, it doesn't address the specific nutritional crash that GLP-1 appetite suppression causes. Nutrafol's own website never mentions Ozempic, Wegovy, Mounjaro, or telogen effluvium from weight loss.

Alluvani: Every ingredient was selected based on the specific nutrient depletion profile of GLP-1-driven caloric restriction: chelated iron (for ferritin), zinc picolinate, methylcobalamin B12 (the form that absorbs even when stomach acid is reduced), vitamin D3, marine collagen peptides, saw palmetto, and biotin. The complete picture, not just one piece.

Yes. Alluvani contains only vitamins and minerals — micronutrients that your body requires for healthy cellular function. There are no known interactions between these nutrients and GLP-1 medications (semaglutide, tirzepatide, liraglutide, or others).

We always encourage you to discuss new supplements with your prescribing doctor or pharmacist, especially if you have other medical conditions or take additional medications. In our experience, healthcare providers who understand GLP-1 nutrition are supportive of targeted micronutrient supplementation during caloric restriction.

Alluvani contains no stimulants, hormones, prescription medications, or controlled substances.

Because biotin alone cannot address GLP-1 hair loss — and this is not a marketing claim, it's a mechanistic reality.

GLP-1-induced telogen effluvium is driven by systemic nutrient depletion: depleted ferritin (from reduced dietary iron), depleted zinc (from reduced food intake), depleted B12 (from GLP-1's effect on stomach acid), and reduced protein availability (for keratin synthesis).

Biotin deficiency is extremely rare in adult women eating even a modest amount of food. Most women on GLP-1 medications who are experiencing hair loss are NOT biotin-deficient. They are iron-deficient (specifically ferritin), zinc-depleted, and protein-low. Taking more biotin in that context does very little.

Alluvani addresses the actual depletion profile. If you've tried biotin and it didn't work, it's not because supplements can't help — it's because you were solving the wrong deficiency.

Topical serums work by delivering active ingredients to the scalp surface and follicle openings. They can be effective at stimulating follicles from the outside. However, they cannot do something fundamental: replenish the internal nutrients that GLP-1 appetite suppression depletes.

Topical application cannot raise your ferritin levels. It cannot replace the zinc your body isn't getting from food. It cannot deliver methylcobalamin B12 to your cells. These are systemic deficiencies that require systemic solutions.

Alluvani works from the inside — addressing the nutritional root cause that drives the follicle-level problem. Both approaches can be complementary, but oral supplementation is the only way to address the internal nutritional depletion that GLP-1 creates.

Please don't make that decision without first addressing the nutritional component. Clinical research has found that hair loss is one of the most common reasons women discontinue GLP-1 therapy before reaching their health goals — and it's a decision many regret, because they gave up progress that was actually working.

Here's what the research tells us: GLP-1 hair loss is a nutritional problem, not a medication problem. The medication is doing its job — suppressing appetite and driving weight loss. The nutritional depletion that follows is addressable. Most women who address the nutritional gap can continue their GLP-1 journey without sacrificing their hair.

Give Alluvani 90 days before making any changes to your medication. Our money-back guarantee means you risk nothing. If after 90 days you haven't seen meaningful improvement in shedding, you get a full refund — and you'll have information to take to your doctor.

Yes — significantly more. Standard nutritional recommendations suggest 0.8 grams of protein per kilogram of body weight per day. But clinical research shows that women on GLP-1 medications actually need 1.2 to 1.6 grams per kilogram per day — that's 50-100% more protein.

Here's why: Your body's reduced appetite makes hitting this higher protein target extremely difficult. Most women eating 40-60% of their normal food intake simply cannot consume enough protein to sustain active hair growth — or muscle maintenance, or other critical functions.

Alluvani includes marine collagen peptides (pre-hydrolyzed amino acids) to help bridge this gap. But meeting your protein needs also requires intentional food choices: eggs, Greek yogurt, lean meats, fish, legumes.

If you're not consciously eating more protein than you normally would, your body is prioritizing it for vital organs. Your hair is last in line.

Hair grows slowly — about half an inch per month. The clinical recovery timeline for telogen effluvium is 3–6 months for full density restoration. Here's what most women experience with Alluvani:

• Weeks 1–4: Nutritional reserves rebuilding. Invisible internal work.
• Weeks 4–6: Most women notice reduced shedding. Less in the drain, less on the pillow.
• Weeks 8–12: Baby hairs visible at temples and hairline — the first visible sign of new growth.
• Months 3–6: Meaningful density and volume improvement. Ponytail recovery.

The 90-day money-back guarantee exists because we know this timeline. We're confident enough in the results to back them fully for the length of a complete hair growth cycle.

Yes — and starting early is actually the best strategy.

Remember the 90-day delay: the nutritional depletion begins on day one of GLP-1 use. Follicles that enter their resting phase in months 1–2 shed in months 3–4. The shedding you see is the result of damage that happened months earlier.

If you start Alluvani within your first 2 months on GLP-1, you're building a nutritional buffer before your follicles reach crisis point. Many women who start early report that their shedding, while present, is significantly less severe than what they hear about from friends and online communities.

Prevention is always easier than recovery.

No — and clinical research supports continuing your therapy while addressing the hair loss.

A 2025 study on therapeutic adherence found that "awareness of GLP-1-associated hair loss may improve therapeutic adherence" (Rojas Lopez et al., Cureus). Translation: when women understand that hair loss is a treatable side effect, they're more likely to continue their medication.

Women who quit their medications because of hair loss are giving up medications that work — not because the medication failed, but because they didn't know the hair loss was nutritionally addressable.

"I've lost 35 lbs and I feel so much better... but I'm watching my hair disappear and I don't know if it's worth it."

The evidence is clear: Your medication is working. The hair loss is a predictable, addressable side effect of that success — not a reason to stop.

What to do instead: Continue your GLP-1 therapy and support your nutrition with Alluvani. You don't have to choose between your weight loss and your hair.

Yes. The nutritional depletion caused by months of caloric restriction doesn't immediately resolve when you stop the medication. Your ferritin, zinc, and other nutrient stores need to be actively replenished — and your follicles need that nutritional environment restored before they can re-enter the growth phase.

Additionally, because telogen effluvium has a 2–4 month lag, hair you're losing after stopping the medication may be the result of follicle stress that occurred during your last months of treatment. Alluvani addresses both the active depletion and the recovery phase.

If you take Alluvani consistently for 90 days and don't see a meaningful reduction in hair shedding, contact us for a full refund. No returns necessary. No difficult questions.

We chose 90 days because that's the clinical timeline for telogen effluvium recovery — it's the honest answer to "how long does this take." We stand behind the formula for that duration. Most women see results within 6–8 weeks. The 90-day guarantee exists for the ones who need more time.

Yes — free standard US shipping on all orders. Expedited shipping options are available at checkout.

Take 2 capsules daily with a meal. Taking with food improves absorption — particularly for the iron component. A small amount of vitamin C (from food or a separate supplement) taken alongside Alluvani improves iron absorption significantly.

Taking in the evening with dinner tends to work well for most women, as the formula doesn't contain stimulants.

In most cases, yes — but check total doses. If you're also taking Nutrafol, a multivitamin, or other individual supplements, check the combined daily intake of vitamins and minerals to avoid excessive amounts of any single nutrient.

Iron is the main nutrient to watch: women with confirmed iron overload conditions should not supplement with iron without medical supervision. For most women on GLP-1 medications, additional iron support is appropriate given the depletion pattern — but if you have hemochromatosis or elevated ferritin (above 200 ng/mL), consult your doctor first.

As always, we recommend discussing your full supplement stack with your healthcare provider.
