Abstract

Objective: The goal of this study was to assess the perceived efficacy of a standardized nutraceutical to improve hair growth and quality in men and women of various ethnicities with self-perceived hair thinning.

Methods: This prospective, single-blind study enrolled healthy men aged 20 to 55 years (n=47) and premenopausal women aged 20 to 45 years (n=51) with self-perceived, mild-to-moderate hair thinning and included African American, Asian, Hispanic Caucasian and Non-Hispanic Caucasian participants. The nutraceutical supplement (Nutrafol® Men or Women Capsules, Nutraceutical Wellness Inc., New York, New York) was taken daily for six months. Subjects were evaluated in the clinic at baseline and Weeks 12 and 24 with two self-assessments at Weeks 4 and 8. Study endpoints were standardized digital imaging and investigator rated assessments. Self-assessment questionnaires rated hair growth, hair satisfaction, and lifestyle factors.

Results: Investigator ratings for baseline hair growth, coverage, density, and volume were significant at Weeks 12 and 24 for all subjects (for each, p<0.001). These significant improvements were seen in 83.7 percent of men and 79.5 percent of women at Week 24. Results were similar across ethnic subgroups with significant benefit at Weeks 12 and 24 (for each, p<0.05). All subjects reported significant improvements in baseline hair appearance/quality, volume/fullness, scalp coverage, thickness, and shedding at Weeks 4, 8, 12 and 24 (for each, p<0.01).

Conclusion: A standardized nutraceutical supplement improved visible hair growth with less notable shedding based on subjects' and investigators' overall perception of treatment benefit for men and women of various ethnic backgrounds.

Keywords: Nutraceutical supplement; ethnicity; hair thinning; men; race; women.
