I have well water and Malibu C Hard Water Wellness Shampoo and Conditioner are a must for me as we have a lot of iron in our water. The products keep highlights fresh and eliminate discoloring from our well water and also keep my hair from being so dry from the hard water effects of well water. I just reordered two more shampoos and also the Hard Water Wellness Remedy packets, which I'm really looking forward to trying. Thank you for your products!
