If you want another leave-in scalp serum, The Ordinary Multi-Peptide Serum for Hair Density is the closest format comparison to VEGAMOUR GRO Hair Serum. If you are seeking treatment for pattern hair loss, topical minoxidil is a different option—not a like-for-like serum substitute. The right choice depends first on what kind of hair loss you have and whether your goal is fuller-looking hair or treatment.
Start by separating cosmetic serums from hair-loss treatment
VEGAMOUR describes GRO Hair Serum as a daily leave-in scalp product intended to support the appearance of fuller, healthier hair. Its listed ingredients include caffeine, turmeric callus conditioned media, clover and mung bean sprout extract, biotin, and peptides. The directions say to apply a dropperful to the scalp daily, massage it in, and leave it on without rinsing. VEGAMOUR’s product page reports results from a 120-day consumer-perception study of 40 participants: 93% saw less shedding, 90% saw an improved appearance of hair, and 83% said their hair felt stronger. These are company-reported perceptions, not a head-to-head clinical comparison with alternatives.

Topical minoxidil belongs in a separate category: the American Academy of Dermatology (AAD) identifies it as an FDA-approved treatment for male and female pattern hair loss. A cosmetic serum’s appearance-focused claims do not establish that it treats pattern hair loss, and minoxidil should not be treated as simply another scalp serum.
Compare the main alternatives
| Option | Category and stated goal | Formula or active | Use and evidence context | Best fit |
|---|---|---|---|---|
| VEGAMOUR GRO Hair Serum | Leave-in cosmetic scalp serum; appearance of fuller, healthier hair | Caffeine, turmeric callus conditioned media, clover and mung bean sprout extract, biotin, and peptides | Apply a dropperful daily and do not rinse. VEGAMOUR reports consumer perceptions from 40 participants after 120 days; this was not a comparison trial. | Someone seeking a cosmetic serum in a daily leave-in format |
| The Ordinary Multi-Peptide Serum for Hair Density | Leave-in scalp serum; fuller, healthier-looking hair and the appearance of density | Caffeine, biotinoyl tripeptide-1, acetyl tetrapeptide-3, and plant extracts | Use a few drops on a clean, dry scalp once daily at bedtime. The brand’s stated aim is cosmetic appearance, not established treatment efficacy. | Someone who wants another serum-format option |
| Topical minoxidil | Treatment for pattern hair loss, not a cosmetic serum | Minoxidil; product concentrations and forms vary | Follow the directions on the specific product. AAD says results may take about six to twelve months and continued daily use is needed to maintain benefits. | Someone considering treatment for diagnosed pattern hair loss, with product suitability confirmed through labeling or a health professional |
The Ordinary Multi-Peptide Serum: the closest serum-format comparison
If your priority is a leave-in scalp serum rather than a treatment specifically intended for pattern hair loss, The Ordinary Multi-Peptide Serum for Hair Density is a relevant comparison. The brand lists caffeine, biotinoyl tripeptide-1, acetyl tetrapeptide-3, and plant extracts, and directs users to apply a few drops to a clean, dry scalp once daily at bedtime. Its stated objective is fuller, healthier-looking hair and the appearance of density.

That makes it similar to GRO in format and cosmetic positioning, but it does not show that either product treats an underlying cause of thinning. The Ordinary notes that formulations can change and that the ingredient list on the box may differ from the website, so check the package you receive. Prices and availability can change; compare current listings before buying rather than relying on an old price.
Minoxidil: a different path for pattern hair loss
The AAD identifies topical minoxidil as an FDA-approved treatment for male and female pattern hair loss. Its guidance says results may take about six to twelve months; daily continued use is needed to maintain benefits, and scalp irritation can occur. The AAD cautions: “Minoxidil can help early hair loss; it cannot regrow an entire head of hair.” See its diagnosis and treatment guidance for context.

Dosing depends on the product, so do not transfer directions from one foam or solution to another. ROGAINE’s FAQ says women’s 5% foam is used once daily and men’s foam twice daily; follow the current label for the exact product you are considering and ask a clinician or pharmacist if you are unsure whether it is suitable. ROGAINE’s FAQ provides product-specific directions.
ROGAINE’s men’s product information identifies its foam as containing 5% minoxidil and warns against use in situations such as sudden or patchy hair loss or hair loss with an unknown cause. The AAD also advises evaluation by a dermatologist because other conditions can resemble female pattern hair loss. Its guidance includes pregnancy and breastfeeding cautions for minoxidil; check the current product label and discuss suitability with a clinician rather than assuming it is appropriate. ROGAINE’s men’s foam information and the AAD’s female-pattern hair loss guidance provide further details.

Choose based on your goal and the cause of thinning
- Choose a serum-format comparison if your goal is a leave-in product aimed at the appearance of density. The Ordinary is a direct format comparison, but its cosmetic positioning is not evidence that it treats pattern hair loss.
- Discuss minoxidil if you are considering treatment for pattern hair loss. It involves product-specific directions and a months-long commitment to continued use; confirm suitability and follow the label.
- Seek professional evaluation if loss is sudden, patchy, unexplained, or otherwise concerning. Hair thinning can have different causes, and a serum purchase cannot establish which one applies.
