I was given Malibu C Hard Water Wellness Shampoo as a gift because my friend knew how hard our water is. My hair was brittle and dry and wouldn't thicken at the ends. After using Hard Water Wellness Shampoo once, my hair looked longer, fuller and just healthier. I've now used it for 6 months and I'm amazed. I finally have to order more and I'm so excited to try the conditioner!
