I recently dyed part of my hair 2 very bright colors. My stylist recommended this shampoo. It works great!!! First time I washed my hair with regular shampoo I saw colors running down the drain. With this shampoo, NOTHING!!! It really makes the difference. The conditioner works well on my hair to keep it soft. I wash, rinse in cold water, put on conditioner, comb through with wide tooth come and put it up on my head while I shower then rinse it out with cold water.
