Norwood Classification – Hair Transplant Before-after Results

Norwood Classification – Hair Transplant Before-after Results

The Norwood classification system is a scale for describing hair loss in men. It was developed by Dr. O’Tar Norwood and James Hamilton, first published in 1975. The Norwood scale ranges from 1 to 7, with 1 being the least severe alopecia and 7 being the most severe.

It can be used to help diagnose hair fall in men, as well as to track the progression of alopecia.   A baldness scale is also useful for predicting the likelihood of baldness treatment success.


Let us take a closer look at Norwood Stages and Talizi Doctors’ hair transplant before-and-after results, in order to see how they dealt with the disease of their patients:

1 – This is the earliest stage of hair loss. The hairline may recede slightly, but there is no noticeable loss of density. At this stage, it is not recommended to use transplantation surgery.


2 – There is a more noticeable fall of follicles, especially in the temporal (front) areas. The hairline may recede further back, but there is still no significant loss of density. Transplantation surgery can be considered at this stage.



3 – This is the most common stage of baldness. There is a significant loss of hair in the temporal (front) and vertex (top) areas, with the hairline receding back further. The density of the remaining hair is also reduced. In addition to the hairline recession and reduction of density, there is now a visible “bald spot” in the center of the scalp.


4 – The bald spot continues to grow larger, and may merge with other spots. There is also diffuse thinning all over the scalp.


5 -There is extensive fall of follicles all over the scalp, including both the bald spots and the diffusely thinned areas. The hairline has receded significantly.


6 – The 6th stage of the Norwood scale is thought to be a more advanced form of baldness and male pattern hair loss. The bridge of follicles that used to cover the crown area is all but gone.


7 – This is the most severe stage of the disease, and is characterized by complete baldness. There is no health cells remaining on the scalp, including eyebrows and eyelashes. This stage is also known as “alopecia totalis” or “totalis” for short.


Using the Norwood classification system, men can diagnose and track their progress. As well as predicting the success of various treatments, it can be used to determine the likelihood of failure. To determine your Norwood class and the best treatment for your disease, consult a doctor.
