About this trial
This will be a 6-month randomized, double-blind, placebo-controlled trial. A total of 152 participants with hair loss, including some with gray hair, will be enrolled and randomly assigned to four groups. Each group will receive a combination of oral capsules and hair tonic, to be used as directed for 24 weeks. Participants will attend three in-person visits, during which assessments-including hair-related tests and photographs-will be conducted to evaluate hair count and density. Additionally, 10 participants with gray hair from each group will undergo extra assessments focused on changes in hair color. All relevant clinical data will be systematically collected and recorded for statistical analysis.
