Guys with mature hairlines

[Tracy C]

The mature hairline thing isn't a myth. It's definitely true for some guys. The problem is you have no way of knowing whether you're just getting a mature hairline or whether it's the first stage in full blown baldness.

The best way is to take good quality photos of your scalp every six months, focus attention on your vertex and mid-anterior regions. That way you can spot the real problem if it starts as it starts.
