Tween hairstyles!!!! Plz help?

hey, i'm looking for a few new hairstyles that are quick and look FAB! My hair is your average shoulder length brown hair with side bangs. I usually straighten it and puff my bangs. What i really want to do is maybe learn how the girls make that wavy hairstyle, i mean i know it takes alot of hairspray and a curling iron but i love the hairstyle and i really want to be able to do it. I'm talking about the hairstyle where its like the whole head is an array of close messy waves. I have NO other idea of how to describe that! Thnx for any answers!
