TLDR No current system perfectly classifies male-pattern hair loss, indicating a need for a new system for better diagnosis and treatment.
The 2017 document "Classification of male-pattern hair loss" discussed various classification systems for male-pattern hair loss (MPHL), including the Hamilton, Norwood-Hamilton, Adapted Norwood-Hamilton, and Basic and Specific (BASP) classifications. Each system had its strengths and weaknesses. The Hamilton classification, based on a study of over 700 individuals, had high reproducibility but lacked clinical detail. The Norwood-Hamilton was practical and widely used but had reproducibility issues. The Adapted Norwood-Hamilton aimed to improve reproducibility but was based on a small study of 16 individuals. The BASP classification was the most detailed but was slow to be adopted due to unfamiliarity. The document concluded that no existing system perfectly balanced detail, practicality, and reproducibility, suggesting the need for a new classification system for better diagnosis, monitoring, and treatment planning of MPHL.
