O Positiv Health Launches New Daily Hair Growth Supplement For Women

Half of all women experience hair thinning or loss in their lifetime, and O Positiv Health is now targeting this overlooked market. The company launched URO Hair Growth + Volume, a daily supplement featuring Serevelle, a proprietary saw palmetto extract that Gainesville.com says was clinically studied for supporting hair growth, thickness, and density. Priced at $36.99 per bottle, the supplement comes as a single daily capsule—unlike competitors requiring multiple pills.
The move reflects a major shift in the hair loss market, which has long focused on men. Co-founder Brianna Bitton said Detroit News: "Over the past few years, countless women have reached out to us sharing their struggles with hair thinning brought on by life's daily challenges, including stress, menopause, and more." A clinical trial showed Serevelle delivered 306% greater improvement in total hair density compared to placebo.
Hair thinning strikes women for many reasons: menopause, postpartum shifts, stress, and aging. Yet most drugstore solutions target men with male pattern baldness. Lansing State Journal reports that O Positiv recognized this gap and built URO specifically for women's hormonal patterns. The supplement combines saw palmetto—which blocks DHT, a hormone linked to hair loss—with other nutrients supporting the hair growth cycle.
A 180-day double-blind trial published in the Journal of Cosmetic Dermatology tested Serevelle against placebo. Results were striking: hair density improved 306% more in the active group. Total hair count rose by 18.6 hairs per area in the supplement group versus a loss of 10.1 in placebo. Vellus hair (fine, short hairs) showed 414% greater improvement. Savannah Now highlights these results as compelling evidence for the formula's effectiveness.
Dr. Kavita Mariwalla, a board-certified dermatologist, endorsed the formulation. She told Argus Leader: "I found URO Hair Growth + Volume compelling because it takes a targeted approach to the hair follicle, combining Serevelle, a proprietary botanical active, with key nutrients for hair health." Saw palmetto's mechanism is well-established in dermatology: it inhibits the enzyme that converts testosterone to DHT, slowing hair loss.
While saw palmetto is generally safe, users should be cautious. Las Cruces Sun News notes that anyone taking blood thinners or oral contraceptives must consult a doctor first, as saw palmetto may interact with these medications. Independent researchers also caution that clinical trials often measure perceived thinning rather than clinical regrowth. Results vary person to person. The supplement works best as part of a broader hair-health strategy including stress management and proper nutrition.
