O Positiv Health, the wellness brand known for its vaginal probiotic products, is entering the hair care market with the launch of URO Hair Growth + Volume. The once-daily dietary supplement is designed to support healthier, fuller-looking hair and target hair thinning and shedding caused by stress, menopause, and other life changes.
What Is Inside URO Hair Growth + Volume?
The core ingredient in the new supplement is Serevelle, a proprietary saw palmetto extract. According to O Positiv, the extract has been clinically studied for its ability to support healthy hair growth, thickness, and density. The formulation also includes Holy Basil, which is traditionally used to support stress management. Additional ingredients cited in product details include biotin, iron, selenium, and vitamins C and B12 to support daily nutrition and address deficiencies sometimes associated with hair loss.
According to Brianna Bitton, co-founder of URO by O Positiv Health, the product was developed in response to customer feedback. “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,” Bitton said in a press release.
Clinical Study Results and Hair Health Context
O Positiv cites research indicating that as many as half of women experience some form of hair loss by age 80. To back up the product’s claims, the brand points to a 90-day, double-blind, placebo-controlled clinical study evaluating the formula.

According to data from that study, users experienced a 12.8x hair density improvement vs. placebo, 17.8x thicker, healthier hair strands vs. placebo, and a 70% reduction in hair shedding among menopausal women.
Dr. Kavita Mariwalla, a double board-certified dermatologist and Mohs surgeon, noted that the supplement stands out due to its specific ingredient combination. Mariwalla stated that the product takes a targeted approach to hair follicle support by pairing Serevelle with nutrients commonly associated with hair health in a single daily capsule format.

URO Hair Growth + Volume is available now on the O Positiv website for $36.99 for a one-time purchase of a single bottle.
