Norwood Scale: Types and Treatments

Medically reviewed by Dr. Sternberg
Male androgenetic alopecia (AGA), i.e. genetic hair loss, follows a typical pattern in most cases, which is illustrated by the Hamilton-Norwood scale. According to this scale, androgenetic hair loss is divided into seven stages. Prior to most hair transplants, the patient’s degree of hair loss is identified using the Hamilton-Norwood scale.
This scale is then used to determine the number of grafts needed for the transplant and to make a prediction about the cost of treatment. The scale can also be used to predict the further course of hair loss.
