Studysummary This article introduces a revised NPRT classification system that includes diverse patterns of hair loss in both men and women, suggesting it as a universal tool for classification and documentation. Our plain-language summary of this paper — not a Tressless recommendation.

In May 2020, a revised NPRT classification system was proposed that expanded its scope to include various patterns of hair loss in both males and females, beyond its initial design for male pattern hair loss (MPHL). This revised system became a universal classification and documentation system for hair loss due to its simplicity, ability to replicate the exact picture of the hair loss pattern, and good reproducibility.

research Modified Basic And Specific (BASP) Classification For Pattern Hair Loss

2 citations , June 2019 in “International Journal of Dermatology”

This study found that while a modified BASP classification for pattern hair loss could classify previously unrecognized types, it was less accurate and harder to use than the existing BASP classification.

research A New Classification of Early Female Pattern Hair Loss

3 citations , January 2018 in “International Journal of Trichology”

The authors concluded that their new grading system can effectively classify early female pattern hair loss and evaluate treatment progress.
