I Still Don’t Understand the Maturing Hairline

You have said in previous posts that in many young men it is normal to develop a “mature hairline.” By this logic a NW 7 seems to me to be simply a hairline that matured to a much greater extent then a mature hairline. Really there is no such thing as MPB by this logic just varying degrees of “mature hairlines” right? I just dont understand how some hair miniaturing through the MPB process we understand is not MPB yet a NW 3 for some reason is when they both occur from same exact processes. Could you explain?

Medical science is a descriptive science. Dr. O’Tar Norwood observed that men seemed to progress in a known pattern and then some of them stopped progressing. This is what eventually became the Norwood classifications for hair loss. It is what it is and Dr. Norwood was brilliant at observing and then recording his observations.

A Norwood Class 7 hairline (or lack of) is a result of genetic male pattern hair loss. A maturing hairline is what young men go though as they lose their childhood hairline (fuzz around the front corners, etc). The general public would not consider a maturing hairline to be balding.
