Hi everyone! Sorry this post has taken me so long to get up. I purchased this shampoo and conditioner about a week ago at Walgreens. I paid under $4 each for both. There is an entire line of the new Keratin Infusion products: shampoo/conditioner, dry shampoo and a 30-day smoothing kit. I knew I only wanted to try the shampoo/conditioner. Plus that, the treatment can only be used on a very small group of people (no bleach, color treated, etc.). There are two types of shampoo/conditioners - one for color treated (the one I have) and a dry/damaged version. THE SHAMPOO CLAIMS (back of the bottle): This lower sulfate, pH-balanced shampoo, formulated with KERALOCK technology gently cleanses to help keep color vibrant, infuses keratin inside the hair fiber and provides lasting smoothness. -vibrant hair -frizz control for up to 48 hours -smooth & manageable hair LATHER: I don't know about you, but lather is very important to me. I know sulfate-free and lower sulfate shampoos don't lather much but I still like it to. This one does. Not a ton but enough for me to feel like it's cleaning my hair. My hair actually felt smooth while rinsing. I can normally tell if I'm going to like a shampoo during the rinse stage.
