When Does The Hairline Undergo Maturation?

[Carll38272]

I've heard it starts in the late teens/early 20s and I've heard it starts in the 30s.

Also, what shape is the "mature" hairline?

Maturation is a bit over played. it's one of those occurrences that you never notice happen.

If you think you are balding, chances are you probably are.
