2 years of hair damage from hard water and after using this product almost instantly I could see my hair getting healthier. I'll never go to another shampoo again. I order this stuff from the United States in a large bottle straight from the Malibu store so I can use this shampoo. This is the shampoo that a professional hair salon will use to clarify your hair Instead of using Apple cider vinegar, or products that will dry out your hair. Absolutely an amazing product. My hair is growing again because I'm treating it right from scalp to tip.
