Ok, so Im growing my hair out at the moment, even though its not really long enough to tie back. This is something of a problem right now for me. I train Brazilian Jujitsu, Mixed Martial Arts and Karate as my main interests, and since I cant keep my hair tidy, it's getting caught during training and I need some advice. I was thinking of getting a bandana or something to tie over my hair if Im going to keep growing it, since Im hoping to go quite long with it eventually. Could something like that work?
