We have the most disgusting well water ever! When you shower it smells like rotten eggs! I started using Malibu C Hard Water Wellness Shampoo and Conditioner plus the Blondes Natural Wellness Treatment and I now have a new head of hair! Gone is the brassy, dry, brittle hair. Now my hair stays blonde longer between coloring and my stylist says my hair is in the best condition ever! Thanks Malibu for helping me have the beautiful blonde locks I have always wanted!
