My hair is naturally VERY curly &thick. I am lucky enough to be able to pull off both looks ;) I straightened it yesterday so today I didn't have to do much to it.
I just used a little comb with close together bristles to tease at the root of my bangs to give it a little more volume, I combed the top of my bangs over it to shape it &smooth it out.
After I held it into place with a small black hair clip. (A small one is better to hold because a bigger one tends to loosten up and that way your hair falls out of it faster.)
Then I used two half size bobby pins to help the hold. I combed the excess hair down nice and sleek.
annnd waalaah!
Here's the "poof":
