Placebo Effect of Topical and Oral Treatments for Androgenetic Alopecia: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis investigates the placebo effect in both topical and oral treatments for androgenetic alopecia. The study, conducted by researchers from Peking University, analyzes data from multiple trials to assess the impact of placebo treatments on hair growth outcomes. The findings suggest that placebo treatments can have a significant effect on perceived hair growth, highlighting the importance of considering placebo responses in clinical trials for androgenetic alopecia. This underscores the need for well-designed studies to accurately evaluate the efficacy of new treatments for hair loss.
