I usually get my hair straightened, so I tried using this to keep it straight, and it definitely works on the frizz better than regular shampoo, making it straighter. It's cheap and available at drugstores, so I think it's great. When I've just had my hair straightened and it's still working, I use the Lux Osmanthus scented product, which I also like because it smells nice. I didn't notice any roughness or anything.
