Jan 02, 2010 - I've been using this product for about a month now and I simply couldn't be more in love! Since I started using this product in combination with AG's re:coil I've noticed a significant improvement in how healthy my hair both looks and feels. I have super-fine hair, so it doesn't take much at all for a product to be too heavy for my hair, but CK is just right. On both the up and down-side this product is water based, meaning I feel completely guiltless when I put it in second-day hair but also have had a bit of trouble controlling how much comes out of the bottle and keeping it firmly in my hand while trying to apply it. Being almost comically clumsy could also be a contributing factor to the later. Bottom line? I love this product. I see that not everyone has had my experience with it, but I love it and my hair look great. I'm hooked.
