TLDR The modified Sinclair scale effectively measures hair loss severity in men.

The document described a modified Sinclair scale adapted for assessing female pattern hair loss (FPHL) in men, categorizing hair loss into 5 grades. Grade 1 indicated normal hair density, while Grade 5 represented the most severe hair loss with little or no hair in the centroparietal region. The anterior hairline was preserved across all grades. The study also included data on the interrater and intrarater reliability of this scale, ensuring its consistency and accuracy in evaluating hair loss severity.
