Norwood Scale


Norwood Hamilton Scale

In the 1950s Dr James Hamilton introduced the first version of the scale and later in the 1970s it was updated by Dr O’Tar Norwood. Since then Norwood Hamilton Scale has become a useful tool for doctors, trichologists and medical team to classify male pattern baldness in the treatment of hair loss. Clinic Center Turkey medical team uses this specific scale while preparing your personalized treatment plan before the hair transplant procedure. You can find the severeness of your hair loss on the scale by seeing the pictures below.

Norwood Hamilton Scale – Stage 1

The least amount of hair loss in the hairline but if you have genetic alopecia, please follow your case closely and decide the appropriate time for the treatment.


Norwood Hamilton Scale – Stage 2

Hair loss at the front temporal sides, triangular-shaped at both parts. Also small amount of alopecia in the middle of the front head. At this stage, determine the reasons for the hair loss, male pattern baldness etc.


For Stages 1 and 2, a small to moderate hair transplant procedure would be beneficial to restore the hairline and can greatly improve the overall appearance and increase self confidence.

Norwood Hamilton Scale – Stage 3

Small to moderate amount of hair loss, from this stage on there is an ongoing condition of baldness. Clear hair loss in the temples with symmetrical recession and small amount of hair loss in crown area. Hair transplant reatment is expected.


For Stage 3, a moderate hair transplant to the frontal hairline and the vertex area as well as the crown would be beneficial to restore density, volume and helps to frame the face.

Norwood Hamilton Scale – Stage 4

Moderate level of hair loss in front temporal sides along with receding hair and open area occurs in crown area. In the middle of the scalp, from hairline to the crown, natural hairs with moderate density is observed solely.

Norwood Hamilton Scale – Stage 5

Moderate to large amount of hair loss mostly at the back and the front temporal parts are separated with medium density natural hairs.


For Stages 4 and 5, advanced hair loss in the frontal hair line, vertex, and crown, an aggressive hair transplant would be beneficial to restore and reframe the face, and by building behind the frontal hairline into the vertex and crown helps to improve the overall appearance and creates more youthful look.

Norwood Hamilton Scale – Stage 6

Large amount of hair loss, from hairline through the crown area with only very thin natural hair and hair loss on the sides are observed more clearly.

Norwood Hamilton Scale – Stage 7

Most severe form of hair loss and natural hair is only available at the back of the head from one side to the another. Because the balding area is very large, hair transplant will only cover a certain part. May require more than one session.


For Stages 6 and 7, although many patients with advanced hair loss have an adequate donor area and pleased with the result of a hair transplant, it is advisable to determine if your donor area is sufficient enough. Hair transplant onto the frontal hairline would be ideal and would rebuild through the vertex and to the crown with as much density as one can transplant in one procedure.
