Ok, this seems to work for me----->
I actually straighten my hair in layers. I start from the bottom layer, then work my way to the top. I take a clip, then pin up all of my hair, except for a small part on the bottom. Then I spray ion straightening solution on my hair, and that's it. I really love the ion spray. It leaves my hair silky and smooth, the only problem is the smell.
But, anyway, it's paraben free, so my hair loves it(:
