This shampoo is the best! I was introduced to it by a hairdresser when I had a bad color job. (Not by her-but she did become my hairdresser) My hair is naturaly blonde and I let someone color it without having a consultaion first. I spent 3 hours having my first foil and when I looked into the mirror I was horified. My hair was an orangy red! I do not like red in my hair, and especially not an orange based red!
I had her redo my hair the next day but it was still bad. I found a new hairdresser and she tried correcting the color and told me to use this shampoo to help eliminate the brassy tones and brighten up the blonde.
This was over ten years ago and I'm still using it. I don't use it every day but I do use it 3-4 times a week to keep my highlights fresh and shiny!
If you are blonde or have blonde highlights this shampoo is a must!
