The Norwood scale helps classify the stages of male pattern baldness on a scale of 1 to 7.

Understanding Hair Loss

The Norwood scale, sometimes called the Hamilton-Norwood scale, outlines seven stages of hair loss that may affect you.

Stage one. Hair loss is not significant, and your hairline is not visibly receding.

Stage two. In stage 2, there is only slight evidence of a receding hair line, generally around the temples.

Stage three. At this stage, your hair loss is significant, and balding becomes obvious. Your hairline recedes deeply near your temples causing your hairline to look like the letters M, U, or V. Your hair may be thinning, or you may be completely bald in those areas. In some cases, you also begin to lose hair around the crown of your head.

Stage four. You have little or no hair along the top middle of your head, also called the vertex. Hair loss increases at your temples and the crown of your head, but there is still a thin line of hair that distinguishes the two areas from one another. You also have hair that is a normal thickness on the sides of your head.

Stage five. Stage 5 shows similar progression to stage 4 but is more severe. There is still a small section of hair between the receding hairline and the balding crown. However, this strip of hair is much thinner than in the previous stage.

In stage 5A, the hairline continues to progress toward the back of the head.
stage 5 would be the stage that you may consider getting a hair transplant operation for your hair conditions.

Stage six. The separate areas of hair loss are no longer divided by a band of thinning hair. All hair on top of your head is completely gone or very sparse.

Stage seven. The only hair remaining on your head is a band that goes around the sides and back of your head. Your remaining hair may be thin or sparse.
