I have been using this for years, and it's the only spray that keeps my wavy hair from growing out of control in the humidity. I tend to use a lot, since I have really thick hair, so I end up buying it pretty frequently. I wish that I could use less and have the same effect. But, it's a good product so I'll pay for it. It one of the only sprays I've found that doesn't leave my hair really sticky. If it's really hot out, I can get away with only using this and letting it air dry, which is amazing considering how thick my hair is. And, it smells good too, a very light smell so I barely notice it. I don't like anything that smells too overpowering.
