My hair was highlighted blonde and I'm originally light brown. I also had some mocha colors in it. Together, they were looking very red and there was a lot of brassiness in the colors. My stylist lightened the bottom part of my hair to add fashion color and on top while the bottom was processing, she added the Malibu C Color Prepare Wellness Remedy. My hair looked blonde and mocha again, not red. It was also much softer than it had been in a long time. Excellent results.
