My client is a platinum blonde. She vacationed in Africa and came back with her hair looking ashy and gold. I have used Malibu C Crystal Gel with good results on hard-to-perm hair as a pre-treatment and I was looking for a product to safely remove the buildup in her hair. Malibu C Crystal Gel, Blondes Wellness Shampoo and Conditioner did an excellent job and she was very pleased.
