Minimum hair length for 1'; hair straightening iron?

I'm a guy and I have curly, semi-red hair. I've never tried straightening before, and because I don't personally like my hair normally, I cut it short (self buzz usually). Right now, my hair is only about 1-1.5 inches long, and I was wondering how long my hair should be before I get a straightening iron. The hair is already starting to curl, and that's why I'm curious.


Thanks.

Have you ever tried hair relaxers? It might get it to uncurl.
