Same as most of the other post here really, been shaving my head with a Mach3 for years and I'm only 25.
The women seem too love it, and I'm forever having girls hands feeling my head
I get bored of shaving everyday or couple so I just do it once a week now as I dont have fast growing hair, and being blonde ( well whats left ) I have no real shadow either so I can get away with it.
I only clipper my face though, so I have rugged look about me.
And I've noticed far more men with no hair problems now shaving or at the very least having a clipperd head than ever before.
