Abstract

Introduction: The NPRT classification system was first described in 2016 and was initially designed specifically for male pattern hair loss (MPHL). We introduce additions that allow for a more comprehensive classification system that encompasses almost all of the patterns of hair loss in both males and females.

Objective: To propose a revised NPRT classification system that encompasses male and female hair loss patterns.

Results: The current NPRT classification system has been revised and various patterns of male and female hair loss have been included that encompass a wide variety of hair loss patterns.

Conclusion: The revised NPRT classification system has become a universal hair loss classification and documentation system because it is easy to understand, can replicate the exact picture of the hair loss pattern, and has good reproducibility.
