In my opinion, braiding it does no good. To me it seems like the curls the braiding gives you eventually wears out (especially if you're outside), and your hair goes back to how it normally is, so you might as well leave your hair. If you leave it, you won't pull/damage your hair. I also suggest wrapping it up at night, so your hair is not rubbing against your pillow case (can break your hair off)! Wash it in the morning, comb it while it is still wet, don't mess with it after it dries! Whalaaa, minimum tangling!
