I struggle with shampoos: if they're too clarifying I get dandruff; too rich I get build up and an itchy patch at the base of my skull. I've been using this for two weeks, every second or third day, and love it. It is thinner than we're used to - I wash twice with about a 50c-sized amount. I have lots of fine, strong hair - this shampoo 'as is' leaves my hair squeaky clean. Paired with the conditioner base, my hair has never been better!
