Validation of Scalp Coverage Scoring Methods for Scalp Hair Loss in Male Pattern Hair Loss (Androgenetic Alopecia)

This study validated the use of scalp coverage scoring (SCS) and global photographs (GPs) for evaluating hair loss in male pattern hair loss (androgenetic alopecia). The SCS method was found to be reliable and accurate in detecting treatment efficacy, with a 5% improvement in scalp hair coverage in the active group compared to the placebo group. The study suggests that SCS can be a useful tool for monitoring changes in hair loss over time and for evaluating the efficacy of drug treatments. The authors caution against using global scalp viewing as a technique for evaluating hair loss.
