system categorizes hair loss patterns and stages
The BASP Classification is a system used to categorize different patterns and stages of hair loss, particularly androgenetic alopecia (male and female pattern baldness). It stands for Basic and Specific, where "Basic" refers to the general pattern of hair loss (such as frontal, vertex, or diffuse thinning) and "Specific" provides additional details about the severity and progression. This classification helps both clinicians and researchers to diagnose, communicate, and study hair loss conditions more effectively.
