Can I get flow in the back of my hair?

Hey, I'm just wondering. So I have pretty long, black hair. And basically before I grew the back out, I had long bangs, so I just kinda swept em to the side. Normally, they were straight. However, after a month or two of doing that, they kinda stayed in that flowy style. It looks awesome to me, however, I'm just wondering, is there any way I can get this same sweeping, "flow" style in the back of my hair? Sorta like Zac Efron's hair is the best way I can explain it. Any products or anything? Thanks! :P
