Good hair products for my hair?

My hair is straight/wavy. It's always been straight but now there's some random waves in it. I recently got a haircut and my hair is now on my shoulder with side bangs, layers, and angles. On one side of my head (where the side bangs are) the layers stick out and the ends flip out. I blow dry it and straighten it, but it just goes back to being the way it was. The other is side is perfect-the ends go in and it stays straight. Is there any good products that will keep my hair straight and the fly-aways in?
