How to stop shoulder-length hair from curling outwards?

[TheDevilInside]

I really hate when my shoulder-leght hair curls outwards. Which happens all the time.

Is there a way to prevent it from making me look like I just came out of a "Hairspray" musical? Without using heat? Because I also don't like using heat on my hair.

They make curl relaxing products. They come in foam, gel, mousse, and spray.
