How we grade a blend. The blend grade is not the grade of its best ingredient, nor an average of its actives. It scores the evidence for the finished product as sold: whether independent (non-manufacturer) randomized trials of the actual formula exist, the quality of any sponsored trials (design, sample size, endpoint integrity, and whether androgenetic alopecia was actually studied), and whether the combination is supported beyond its individual ingredients. An ingredient can earn a C on its own while the blend earns an F — because the dose is undisclosed and the finished product was never independently tested. Independent product-level RCTs would raise the grade.

What's in it

Every active inside Vegamour, graded

We took every active ingredient Vegamour lists and assigned each one a grade based on its standalone evidence for androgenetic alopecia. Click "Full page" on any active to read its complete evidence breakdown.

Active (dose)	Our grade	Our take on this ingredient for AGA
Mung bean extract→Proprietary	F	Marketed as a phytoactive growth factor source. No peer-reviewed AGA evidence at any dose, in any form.
Red clover extract→Proprietary	F	Contains isoflavones marketed as mild phytoestrogens / 5-AR inhibitors. The in vitro data is suggestive; the topical AGA evidence does not exist.
Curcumin (turmeric)→Proprietary	D	Generic anti-inflammatory rationale. No topical AGA RCT data.
Niacinamide→Proprietary	D	Has some general scalp/skin barrier evidence at the cosmetic level. No specific AGA evidence.
Karmatin (proprietary peptide) Proprietary	F	Vegamour's signature ingredient — a 'vegan keratin' marketing construct. No independent characterization or peer-reviewed efficacy data exists.

Grades reflect each ingredient's evidence for hair loss specifically, not its general nutritional or health value. A "D" or "F" grade for hair loss does not imply the ingredient is harmful — only that it doesn't have strong AGA evidence at the doses studied.

Methodology flags

The tricks the marketing plays

Every nutraceutical brand uses some combination of these tactics to make their evidence look stronger than it is. Here's what to watch for on this product specifically.

⚑ No peer-reviewed RCT

No peer-reviewed RCT exists

We could not find a single peer-reviewed randomized controlled trial of GRO Hair Serum in PubMed or any indexed medical database.

⚑ Consumer-perception only

Evidence is consumer questionnaires

Marketing claims like '52% saw thicker hair' come from internal customer satisfaction surveys, not from blinded hair-count studies.

⚑ No placebo

No placebo or vehicle control

Without a placebo arm, you can't distinguish drug effect from regression to the mean, seasonality, or expectation.

⚑ Proprietary blend

Karmatin and other actives have no public characterization

When a brand invents a name ('Karmatin'), trademarks it, and provides no independent characterization, the ingredient is a marketing construct — not a researched molecule.

⚑ Vehicle effect likely

Any topical can make hair look better short-term

Conditioning ingredients and humectants make hair look thicker and shinier for hours after application. That effect is real but cosmetic — it doesn't grow new hair.

Bottom line

Our verdict on Vegamour

Mostly cosmetic

Vegamour's GRO Hair Serum is positioned as the natural alternative to minoxidil. We could find no peer-reviewed RCT of the product. The 'clinical' claims in marketing trace back to internal consumer surveys with self-reported endpoints — a study design that cannot distinguish active effect from placebo, seasonal cycling, or the cosmetic effect of any well-formulated topical. The individual ingredients (mung bean, red clover, curcumin, niacinamide) have either no peer-reviewed AGA evidence or only weak inferential mechanism support. Karmatin, the signature peptide, has no public characterization. If you want a topical that makes your hair look better immediately, this product likely does that — most topical serums do. If you want regrowth measurable by phototrichogram, the evidence isn't there.

Vegamour markets like a science-backed product. The science is a customer satisfaction survey. At $58/month for a no-evidence formulation, this is style over substance.

An evidence-backed alternative

If you want an evidence-backed botanical topical

Au Naturale uses watercress, melatonin, caffeine, and adenosine — each with peer-reviewed AGA mechanism or efficacy data, even if none is FDA-approved. It costs $42/month — less than Vegamour — and the ingredient list reads as 'these molecules have papers' rather than 'these molecules have trademarks.'
