This shampoo absolutely exceeded my expectations! I learned about Malibu C from my stylist who uses it on clients before any chemical services. However I don't bleach nor color, I love my hair's natural color but I wanted something to enhance shine and reflections. I decided to try this one as I live in an area with extremely hard water. I am impressed! There was a real difference after the first use! My hair feels really clean, without any residues and is so much more voluminous! I'm a real proof it brings great benefits even to virgin hair!
