I have used nearly the entire range of Moroccanoil shampoos and conditioner and I really notice a difference when I do. I tried out the clarifying shampoo and was also really impressed. I like to use it once a week as I wash my hair everyday as I gym. I find that it really gives my hair a deep cleanse and adds so much volume too. It is really good if you use lots of product and need to get rid of build up.
