Introduction to the Norwood Scale

The Norwood Scale, often referred to as the Hamilton-Norwood Scale, is a globally acknowledged classification system for determining the severity of male pattern baldness. Introduced by Dr. James Hamilton in the 1950s and later enhanced by Dr. O'Tar Norwood in the 1970s, it breaks down male hair loss into various stages. Comprehending the Norwood Scale is pivotal for patients and hair transplant practitioners alike, as it guides realistic expectations and the selection of suitable hair restoration methodologies.

History of the Norwood Scale

Dr. James Hamilton initially delved into the genetic attributes of hair loss, and Dr. O'Tar Norwood built upon Hamilton's work, formulating the universally accepted seven-stage scale. Since then, the Norwood Scale has set the benchmark for assessing male pattern baldness and is indispensable in the hair transplant domain.

The Seven Stages of the Norwood Scale:

Stage 1 - No Significant Hair Loss

At this stage, there is no apparent hair loss, and the hairline is normal.

Stage 2 - Minimal Hair Loss

Hair loss is minimal, with a slight recession of the hairline around the temples.

Stage 3 - Mild to Moderate Hair Loss

The hairline continues to recede at the temples, forming a more noticeable M-shape. Hair loss may also affect the crown (vertex).

Stage 4 - Moderate to Advanced Hair Loss

The M-shaped hairline becomes more pronounced, and the hair on the crown continues to thin. A distinct band of hair separates the receding hairline from the balding crown.

Stage 5 - Advanced Hair Loss

The M-shaped hairline becomes more pronounced, and the hair on the crown continues to thin. A distinct band of hair separates the receding hairline from the balding crown.

Stage 6 - Extensive Hair Loss

The bridge of hair that once separated the frontal hairline from the crown is now gone, leaving only sparse hair on the sides and back of the head.

Stage 7 - Severe Hair Loss

Only a band of hair remains around the sides of the head, connecting to the remaining hair on the back.
