Revised NPRT Classification System Encompasses Additional Patterns of Male and Female Hair Loss

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.
