I am blonde with thick hair, but I still have to wash my hair almost every day because it gets greasy. Malibu C Hard Water Wellness Shampoo and Conditioner really made a difference in keeping my hair from getting dry and gross. My sister stayed with me a couple of days over the holidays and used it. She gushed about the way her hair felt and looked afterward and asked me where she could get it. She lives in an area with more hard water which turned her thin, blonde hair orange, but the Hard Water Wellness Shampoo and Conditioner definitely saved it!
