I bleached my hair once and then applied blue-purple on top, but I was really afraid it would fade to khaki or a trashy color later. Even though it was a bit pricey, I decided to try this product and I’m 100% satisfied. I used it almost every day, and since this shampoo isn’t very strong in cleansing, I first washed my scalp with a shampoo for oily hair to prevent any odor, then used this. My hair color looks so beautiful that people ask if I just dyed it, and strangers even asked what color it is. Highly recommend! I’m even thinking of using it continuously after dyeing my hair pink.
