I received a sample of this and once I tried it I was hooked. I had to go out and purchase a full bottle and also the conditioner. This is one of the best shampoos I have used. The way it moisturizes and cleans without stripping your color will amaze you, it also helps keep your color truer longer. My hair feels so much better since using this, it has so much more shine than it had before. I love all the L'Oreal Shampoos but I think this is my favorite. L'Oreal shampoos are affordable and that is a must in my household with the economy the way it is today. I highly recommend at least trying this shampoo. Effectiveness This shampoo is great for colored hair, it cleans without stripping your color. It lathers great which is a must for me. Your hair will not feel weighed down and flat using this shampoo. Scent I love the scent of this shampoo, it is a very pleasant, nice scent, not overwhelming like a lot that are on the market today.
