We have well water and our water is harsh on my daughter's and my hair. Our hairdresser told us to try Malibu C products. We used Malibu C Miracle Repair on my daughter's hair which is highlighted and curly. Her hair was so soft, it was amazing! It had shine and softness and when blown straight, was stunning. We are not going to try the Hard Water Wellness Collection. I'm sure we will be thrilled with the results!!
