Malibu C Hard Water Wellness Shampoo has saved my hair and color! I live in a very rural part of Missouri and our water is not what you would call the softest so buildup occurs. I have had colors not turn our right and hair that is just over-mineralized. Hard Water Wellness Shampoo SAVES THE DAY! Best part about it is I just have to use the shampoo once and I'm good to go! Wonderful, wonderful stuff! I share with all my friends, family and clients!!
