I moved to a new home and after a few months I noticed my hair looking brassy, darker and breaking. After speaking with my stylist, she suggested it could be due to hard water. So we used the Hard Water Wellness Treatment on my hair and the results were amazing! We have since had our water tested and installed a softener. Our water is horrible, it is extremely hard and the iron is off the charts. Thankfully, I am able to stay blonde by using these Malibu C treatments along with the shampoo and conditioner.
