I bought this because I work in a very humid environment and I have thick hair that is dry and responds horribly to humidity. Frizz isn't really the worst thing in my world, but my hair feels SO instantly dried out in high humidity, so I purchased this just for the humidity protection properties. I was looking for something that I could use like a leave in cream on wet hair, just air dry and go.
PROS: You know, this isn't a "good" thing but this is a heavily scented product and it smells quite nice. I like it. Also, a little goes a long way.
CONS: This can be heavy. My waves can be a bit loose or delicate but this will kinda of knock them out. I also don't think it does really much for the humidity either. I should have gone for the one below, the Instant Deflate with a frizz protection factor of 30. That one is more silicone based. And although I think my hair is on the coarse-side, I would say this is more for hardcore coarse texture like really curly hair or Afro textures. When I am air drying my hair with this in it, it can look like I have a straightening product in it, no joke.
UPDATE: August 14, 2018. I'm downgrading this to 1 star. It does NOT work for me. I bet I could put the entire bottle of this in my hair on a humid day and my hair would feel just as dry. Really, my hair feels like hell. My hair is healthy and on the thick side, but humidity makes it feel coarse and hay-like and this does nothing to remedy it. I also get that lovely halo of random hairs in the top. I still am a bit perplexed as to why this is a water based product when it's for frizz protection of a high level. Like I mentioned above, the one below this is silicone based and water free. That might work better for me. Also, it will not kill your texture. I used it with a lighter conditioner, and my hair still waved and curled. It will help to straighten it out, and it doesn't give confidence as its drying, but it actually doesn't kill texture like I originally thought.
