I live in a part of North Carolina where we have lots of iron in our water. Even with a high-end water system on our well, my hair was still getting that ugly orange cast to it. One Hard Water treatment and daily shampooing with the Hard Water Wellness Shampoo has removed every bit of the iron deposits! My hair feels so silky soft and it shines with the shade of blonde it's supposed to be. I'm hooked on Malibu C products!
