I tried the bald look 4 years ago...
In order to look good as a baldie you need:
A well built physique
A round shape of your skull....no creases...no bumps...
A good tan
A round face always look better than an oval face
If I were to go back to a shaved head I would opt for a #1 or # 2 as it easier to maintain and no need to use the razor almost every day..
