Norwood Savin Hair Loss Scale

Norwood Savin Hair Loss Scale

The Hamilton–Norwood Savin Hair Loss Scale is used to classify the stages of male pattern baldness. The stages are described with a number from 1 to 7.

This measurement scale was first introduced by James Hamilton in the 1950s and later revised and updated by O’Tar Norwood in the 1970s. It is sometimes referred to as the Norwood–Hamilton scale or simply the Norwood Savin Hair Loss scale.

The scale is regularly used by doctors to assess the severity of baldness, but it is not considered very reliable since examiners’ conclusions can vary.

The progression of female pattern baldness (Androgenic Alopecia) is generally classified on the Ludwig scale, which ranges from stages I to III. Stage I begins with thinning on the top of the head. In stage II the scalp starts to show. Finally, all of the hair at the crown of the head may be lost when the hair loss progresses to stage III. However, the scale is used merely for general categorization. Many women don’t actually fit into the Ludwig stages. – Wikipedia.
