Just about anyone can pull off a bald head. If you are hesitant, just run the clippers a notch shorter every few days until you are buzzing your head with no guard. It will look like you have shaved your head. The the best part is when you actually break out the razor and shave your head for that smooth FEEL. It's hard to go back to hair once you've felt the smooth feels of a bald head.
BBC is great. It does take some determination to keep at the regular head shaves, and you go through blades faster as there is more hair to cut, but worth it all.
You can do it.
