Gweneth Paltrow's hair

I just got my hair cut like Gweneth Paltrows yesterday. Though I LOVE the look, my hair is always poofy. I have frizzy wavy hair naturally, its very fine and very thick. I straighten it with Citre Shine Straightening Balm. This makes my hair soft and adds lots of body, with no frizz. Well now its so poofy and wavy, I dont know what to do. I've been clipping it back but that doesnt help much at all. When I got home, my hair person had put SO MUCH stuff in it that it was all over my hands, and my hair was greasy. I dont want that but when it was like that, it looked really good. Pomade might work, but it also is very sticky, greasy, etc. I want it to be thinner, and flatter... Any suggestions?

Here's another idea. Instead of using the straightening iron. Use A Vidal Sasoon blow dryer w/brush and comb attachment. It has a brush attached to it, so there is no more fumbling with both a brush and blowdryer. Use the straightening balm, along with the blow dryer it is less damaging than the iron. I have naturally curly hair, that can turn out poofy if I don't use this blow dryer, my hair comes out so silky and flat. I couldn't live without it. The blow dryer only costs about 20 dollars depending on where you purchase it.
