“Double-blind, placebo-controlled RCT of 22 women with self-perceived thinning hair. Oral Equisetum arvense (horsetail) extract containing organic silicon for 90 days significantly increased hair tensile strength and thickness versus placebo, consistent with silicon's role in keratin cross-linking and collagen synthesis in hair and nails.”Araujo et al., Anais Brasileiros de Dermatologia, 2016
“Open-label clinical study evaluating choline-stabilized orthosilicic acid (derived from horsetail) at 6-12 mg silicon/day for 20 weeks in 50 women with thin hair. Supplementation significantly improved hair morphology (elasticity, break load, and tensile strength) versus baseline, supporting dietary silicon's contribution to keratin-based tissue integrity.”Wickett et al., Archives of Dermatological Research, 2007
