My hair is so.. BIG! how can I deflate it? (The 80s would be jealous)?

My hair isn't that thick, but it's frizzy so I twist my hair like this a href="http://image.shutterstock.com/display_pic_with_logo/95743/95743,1207061730,6/stock-photo-young-girl-with-red-twisted-hair-isolated-11001547.jpg" rel="nofollow"http://image.shutterstock.com/display_pi…/a (haha sorry about the weird pic) when I blow dry it . I also think big hair like that looks better/is easier to style when it's longer and you can do more with it.
