The Norwood hair scale is a widely used tool for classifying male pattern baldness (MPB). Developed in the 1950s by Dr. James Hamilton, it consists of seven stages, ranging from a full head of hair to complete baldness.
The scale is a valuable tool for both medical professionals and patients, as it can help to track the progression of hair loss and determine the best course of treatment. It has also played a key role in research into the causes and effects of MPB.
