Men typically develop “bald spots” and/or a receding hair line as they age. The most common measurement used in classifying the level of hair loss in men is the Hamilton-Norwood Scale. Dr. James Hamilton first developed The Hamilton Scale in the 1950s, which was later revised and updated by Dr. O’Tar Norwood in the 1970s. Today, this scale is commonly referred to as the Hamilton-Norwood Scale.
The Hamilton-Norwood measurement system ranges from a level one, which represents little to no hair loss, to a level 7, which is characterized by severe baldness where only a rim of hair remains. It’s important to remember that there are many variations in hair loss, but the classifications on the Hamilton-Norwood Scale are the most common.
Why is the Hamilton-Norwood Scale important? Well, your position on the scale can help determine which hair loss solutions will work best for you. Additionally, it can help you refer to the type of hair loss you’re experiencing or concerned about in conversation with hair loss professionals. It can also serve as a tool to help you monitor how your hair loss is progressing over time.
- A normal head of hair with no visible hair loss
- There is only a small amount of hair loss; A receding hairline and widow’s peak on the forehead are present
- Same receding pattern as level 2 except the hairline has receded deeper into the frontal and temporal areas
- Hairline has receded more significantly in the frontal region and temporal area than level three and there is the start of a bald spot at the back of the had
- Similar in pattern to level 4 but hair loss is more noticeable on the top of the vertex and crown
- The strip of hair connecting the two sides of the head existing in levels 4 and 5 is no longer present
- This is the most severe level of hair loss; Hair is receding all the way back to the base of the head and the sides just above the ears
