I have been using Malibu C Hard Water Wellness Shampoo and Conditioner for about six years. I have well water and it is really hard on our hair. At one point, the well water turned my daughter's hair green and Malibu C Hard Water Wellness Shampoo  took it right out and left it really soft. Currently, we have a lot of iron in our well water so we will continue to use Malibu C products! They work great!
