I know what you mean, well, sort of. My hair gets curly the longer it grows but it otherwise a bit wavy. Find what works for you and go for it. It's not the best feeling knowing you either can't do a certain style or it doesn't look good on you, but knowing how to style yourself can be beneficial at times. If you're hair is really curly, as in it curls even when short, keeping it short on the sides and back and a bit longer at the fringe, styling in its natural direction is always a safe bet.
