Pathogenesis and Classification of Female Pattern Hair Loss

Female pattern hair loss (FPHL) was identified as a significant issue affecting approximately 21 million women in the United States, with up to 80% experiencing noticeable hair loss by age 60. Unlike male pattern hair loss, androgens were not considered the primary cause of FPHL, although genetic and androgenetic factors were present. The term "female pattern hair loss" was preferred over "androgenetic alopecia" to better reflect the condition's multifactorial nature. The document emphasized the need for dedicated hair loss physicians to address this prevalent condition.
