A Prospective, Randomized, Double-Blind, Placebo-Controlled Clinical Study of Efficacy and Safety of Ashwagandha Root Extract Capsule on Skin and Hair Health in Healthy Adults

This study evaluated the efficacy and safety of Ashwagandha root extract on skin and hair health in healthy adults aged 18 to 60 with hair loss or skin conditions. Participants were randomized to receive either Ashwagandha capsules (300 mg twice daily) or a placebo for 75 days. The Ashwagandha group showed significant improvements in transepidermal water loss, hair density, growth, and quality of life related to skin and hair, compared to the placebo group (p < 0.05). No adverse events were reported, suggesting that Ashwagandha root extract may enhance skin and hair quality in healthy adults.
