O Positiv announced URO Hair Growth + Volume on August 18, 2026, describing it as a once-daily capsule for women 18 and older. The company listed a launch price of $36.99 and direct-to-consumer availability through its website. Those are launch-time details, not confirmation of today’s price or availability.
What URO Hair Growth + Volume is
URO Hair Growth + Volume is a dietary supplement capsule marketed by O Positiv to support thicker-looking hair, density, volume and reduced shedding. O Positiv’s corrected launch release appeared August 27, 2026, after the August 18 announcement. The company positions Serevelle™ as the formula’s featured ingredient.
O Positiv’s product page describes a serving as one capsule and lists 30 servings per container. The company recommends taking one capsule daily and using it consistently for three months. These are the brand’s directions, not an independent assessment of effectiveness.

What the company says about results
O Positiv reports results from a 90-day, double-blind, placebo-controlled study: 12.8 times the hair-density improvement versus placebo, 7.8 times thicker, healthier strands versus placebo, and a 70% reduction in shedding among menopausal women. These are manufacturer-reported figures. The cited study texts were not independently reviewed for this article, so the numbers should not be read as independently verified findings or a promise that each user will experience similar results.
The product page cites a 2025 Journal of Cosmetic Dermatology article by Glynis Ablon and a 2026 International Journal of Cosmetic Science paper by David Broadley and colleagues. The brand says visible new growth may take eight to 12 weeks or longer and that its study measurements were taken at 90 days; that is the company’s explanation, not a guaranteed timetable.

- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
O Positiv’s release also says the product was third-party tested, but it does not identify the tester or provide a report in the material cited here. That statement does not establish a particular certification or independently verifiable test result.
Launch price and availability
At launch, O Positiv said the capsules were available directly through its website for $36.99. The release initially described direct-to-consumer exclusivity. This is a launch-time price and channel; current price, stock and availability elsewhere are not established here. The company’s comparison describing the product as nearly half the price of alternatives is marketing, not an independently verified price comparison.
Rank #3
What to consider before taking it
A supplement marketed for hair support is not a diagnosis or treatment for the cause of hair loss. O Positiv advises consulting a health care provider before combining supplements, particularly if you are pregnant or nursing, have a medical condition, or take medication. Its product page also states that its claims have not been evaluated by the FDA and that the product is not intended to diagnose, treat, cure or prevent disease.
If comparing women’s hair-growth supplements, useful points to check include the amount of each ingredient per serving, the cost per serving, the quality and accessibility of evidence, and whether the product is intended for your circumstances. Broad efficacy promises alone do not establish that a supplement is appropriate for a particular person.
