I have very course, long blonde hair. And it always had a "brassy" look approximately four weeks after toning. I finally purchased Malibu C as I had seen the products at the beauty show) and was amazed at how great my hair looked and felt. No more brass no more dry, frizzy hair. Of course the fact that the products are vegan is a bonus. So far I have used the Malibu Blondes treatment, Hard Water, Color Prepare and Miracle Repair) as well as the Malibu Blondes Shampoo + Conditioner. I use the Swimmers Shampoo occasionally over the summer and recommend it to everyone I know. Thank you for the great products!!! You have a customer for life.
