I have naturally brown hair with light blonde highlights. I have tried every product out there to keep my highlights bright and reverse damage that continuous highlighting has caused over the years. Malibu C Color Wellness is my go-to shampoo. It leaves my color brilliant and true. It has also given my hair softness and shine. Must try! Since I have opted to go even lighter and heavier with highlights I might try the formula specifically for blondes. ;-)
