I shaved my head for a while and loved it. Low MX, faster prep time in the morning, impossible to screw up. Once I had it shaved, I just used my electric razor every few days to keep it clean. Unfortunately, my skull is large, lumpy, and ugly. So I grew it back. My wife has seen the pictures and threatens divorce if I do it again. After a few pay raises, when I can afford that, I might consider going back to the clean look.
If you like it, stick with it, if not, its only hair.
