Abstract: 
Hair thinning and scalp disorders are prevalent conditions influenced by environmental, hormonal, and lifestyle factors. This study evaluates the clinical efficacy and safety of Narasimham Hair Oil, a traditional Ayurvedic polyherbal formulation, in enhancing hair growth, improving scalp health, and increasing user satisfaction. In an open-label, single-arm clinical trial, 100 participants (50 males and 50 females, aged 20–45 years) with clinically diagnosed hair thinning applied Narasimham Hair Oil thrice weekly for 8 weeks. Objective outcomes included hair density, hair thickness, and scalp health scores, measured at baseline, week 8, and post-treatment week 10. Subjective outcomes were assessed via self-reported questionnaires. Significant improvements were observed in hair density (from 84.8 ± 6.3 to104.0 ± 5.8 hairs/cm²), hair thickness (from 0.064 ± 0.005 to 0.077 ± 0.006 mm), and scalp health scores (from 2.9 ± 0.6 to 1.1 ± 0.4) by week 8, with sustained benefits at week 10. Subjective feedback indicated high user satisfaction, with 95% reporting stronger hair and reduced hair fall. No adverse effects were reported, confirming the formulation’s safety. These findings establish Narasimham Hair Oil as a credible, natural therapeutic option for hair thinning and scalp-related concerns, bridging traditional Ayurvedic wisdom with modern clinical validation.
