Summary
In plain language
This 2025 clinical trial demonstrated that Nutrafol, a blend of standardized botanicals and nutrients, improved hair growth and scalp coverage in men with mild-to-moderate thinning. The study design was strong, statistically valid, and safe for long-term use. While younger participants limit direct senior applicability, the findings are relevant for age-related hair loss.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This randomized, double-blind, placebo-controlled trial evaluated a nutraceutical supplement (Nutrafol) for male hair thinning. Over 24 weeks, participants receiving Nutrafol showed significant increases in hair count, thickness, and self-perceived fullness compared to placebo. The supplement was well tolerated with no major adverse effects.
