I have fine, thin, oily hair -- a perfect recipe for limpness. I have tried many shampoos, but they either were too strong and stripped my hair dry, or had moisturizing elements and left my strands limp as a wet noodle. I was suspicious of this when I got a sample, but gave it a try. Wow! My hair was clean, but not dry, and had great body. I even had friends ask me if I had gotten a new haircut, and how it was cut to get such volume. Love this stuff!
