I used Malibu C Crystal Gel on my client with hard water and iron buildup that had turned her colored blonde hair orange on the ends. Crystal Gel completely removed all the orange and then I used Miracle Repair which made her dry, drab hair shiny and vibrant blonde! I used Malibu C Scalp Wellness just the other day on a client with product sensitivity, itchy scalp. Waiting to hear from her if it helped.
