I had a client who came in for her routine 6-8 week foil appointment. Her tresses had turned orange rather than their gorgeous blonde color. After finding out the cause was due to her husband not changing the water filer in their shower (they live in a well water area), I turned to Malibu C. I followed the instructions on the Hard Water Wellness Treatment to ensure the best possible outcome. The complete process resulted in her hair becoming shinier, softer and all the brassy tones disappearing. After drying her hair, I was then able to foil with confidence, knowing that what had been on her hair prior was gone.
