Use the Norwood Hamilton Scale to determine the stage of your hair loss.

Measuring hair loss: The Norwood Hamilton Scale

The Norwood Hamilton Scale is a seven-stage classification system for male pattern baldness. Created by Dr. James Hamilton in the 1950s and then revised by Dr. O'Tar Norwood in the 1970s , it's a useful system for classifying the level and severity of a man's hair loss so a hair replacement specialist can provide the best treatment options. 

Hair loss patterns
When a man's hair begins to thin, it usually starts at the temples. This is Stage One of the scale, and if you start to experience this, it's only a cause for concern if your family has a history of baldness. When the hair around the temples begins to thin out, usually in a triangular shape along with thinning in the central part of the scalp, then it's evident that you're in the early stages of male pattern baldness. 

"Later stages require hair restoration surgery, such as FUE."

As the scale progresses and hair thins, treatment options begin to thin out as well. Some drugs or simple topical treatments could help stop hair loss in the early stages, but the later stages will require hair restoration surgery, such as FUE. 

Seven stages
The scale comes in seven different stages, from minimal hair loss to the most severe hair loss. Below are four of the most notable stages. For diagrams of each stage, visit the American Hair Loss Association

  • Stage Two hair loss is very light, and usually symmetrical at the front temporal area. At this point, it's clear that the person is in the early stages of baldness. 
  • At Stage Three, a man experiences a symmetrical recession at the scalp and the temples. They may be sparsely covered with hair. While this is considered baldness, it's the lowest stage according to the scale. 
  • Stage Five features hair loss at the crown and temples. There may be a thin line of hair separating the two bald areas. The remaining hair is taking on a horseshoe shape. By this stage, hair replacement surgery will likely be your only treatment option. 
  • At Stage Six, the bridge of hair that crossed the crown is mostly gone, with sparse hair if any. The two balding regions, at the temples and the crown, have joined together. 
  • Stage Seven is the most severe stage of male hair loss. By this point the man is almost totally bald, with just a narrow horseshoe-shaped band on the scalp and sides of the neck, if any.
