I LOVE the Malibu C Blondes Wellness Treatment! I use it once a week between shampoo and conditioner. It's super easy to use and it helps my blonde stay fresh, vibrant, glossy and beautiful! I have a major problem with my hair color turning coppery and brassy way too easily and this product has tremendously helped to solve that issue!! My hair is soft and shiny after I use it. I never want to be without it now. Thanks!!
