The progression of male pattern baldness is generally classified on the Hamilton–Norwood scale, which ranges from stages I to VII.[1]
This measurement scale was first introduced by James Hamilton in the 1950s and later revised and updated by O'Tar Norwood in the 1970s.[2] It is sometimes referred to as the Norwood–Hamilton scale or simply the Norwood scale.
