Most hair supplements rely on long lists of vitamins like biotin or collagen to nourish existing hair. Triquetra Health argues that this approach ignores the root cause of thinning, which occurs deeper within the follicle due to hormonal shifts that shorten the growth cycle. Folura shifts this focus by centering on Serevelle, a standardized saw palmetto extract that supports DHT balance and the hair's natural growth phase.

The effectiveness of this specific dose was highlighted in a six-month, double-blind, placebo-controlled trial published in the Journal of Cosmetic Dermatology. Participants receiving the 160 mg dose of the extract demonstrated a 306% greater total hair density compared to the placebo group. The company emphasizes full label transparency, disclosing the exact amounts of Serevelle and its companion botanical, cold-pressed pumpkin seed oil, without the use of proprietary blends. The product is now available for purchase on Amazon and the company’s website.
