GlossaryHamilton-Norwood Scale (Hamilton-Norwood Classification)

classification system for male pattern baldness stages

The Hamilton-Norwood Scale is a classification system used to measure the extent and pattern of male pattern baldness. It ranges from Stage 1, indicating minimal hair loss, to Stage 7, which represents the most severe form of hair loss with only a band of hair remaining around the sides and back of the scalp. This scale helps both laypeople and professionals understand and communicate the progression of hair loss in men.
