13 years ago I started going to the gym because my hair started thinning. I was convinced a tall slim guy would look weird bald.
I still have my hair albeit thinner than it was then but still there. I wonder if a life style change helped with that.
Clean shaven and bald is definitely a difficult mix, probably a reason most people try to grow a beard. The hipster bald glasses beard look is cliched but preferable to your hair being half missing!
I don't think I could pull it off though, at least right now. I have a taller, lankier statue and I worry I'd look like a skinhead.
I've seen some smaller guys pull it off as well, but they're usually shorter. Most guys that go clean shaven with my kinda build end up looking goofy.
On the flip side, long hair on bigger guys always looks odd to me.
