I have naturally poker-straight hair but got a perm so I wouldn't have to curl my hair all the time - I was recommended this by a naturally curly haired stylist as we were chatting and I was telling her we were going on a hot vacation. She said it worked wonders for frizz control, and it does - stood up to the Caribbean air, and also the Canadian prairie winter's static! Leaves my hair smooth, yet holds pretty well - doesn't look like I have product in it, smells light and not overpowering. It has a conditioner-like look when pumped out, and I don't have to use too much. Works very well with scrunching damp hair, which means I barely have to spend any time on my hair. Don't like that I have to go to a particular store to get it, but it is good when it goes on sale - time to stock up then. I feel like it could be less expensive, but haven't found a good alternative.
