Cornrows are nice for about the first four days then it starts coming loose and have to be redone. When I had my hair down to my belt I used to get it rowed every 3 days by this girl I was seeing. It was nice but gets annoying if you don't keep up on em.

Perm?? Like straightening it? If so I would say no let the fro grow a bit and just keep it fairly tight just enough to give a puff if you know what I mean.

I like my hair high and tight now so my choice for me is pretty close to shaved at about 1/2" down to a zero guard.

Just depends on what you look like and your proffession really.
