How Do You Get Hair Like CeCe Jones in Shake It Up?

I really like curly and wavy hairstyles and I love how they do Bella Thorne's hair in "Shake It Up". I own a Revlon curling iron (but it's probably 3/4 of an inch wide) and a Remington straightening iron. I have straight brown hair and I don't have bangs like Bella. I usually part my hair on the left side, but not super far over. My hair doesn't always hold curls very well, so what can I do to hold curls and waves better? and what can I do with the very little hair styling stuff that I have? I just have your basic mousses and hairsprays.
