My dad was bald as a coot at 25 and I've still got mine at 43.
I did sport a shaved head for a long time but with the influx of bald English yobs in Thailand, it sort of lumped me in with that lot, so I grew it out again.
I'd go bald again in a heartbeat where it not for that association. Easy to maintain, very comfortable in the hot weather and looked decent - even when suited & booted.
As for involuntary baldness when/if it does hit - I guess I'd be 50 or so and getting chicks is hardly going to be a major consideration at that point - so who gives a shit?
I think it's all about how you carry yourself anyway.
If you feel good, you look good.
