not used yet
i have been in the process of dyeing my hair to get to the silver gray look and needed a shampoo to help keep the color. so i decided to go with this. I have not yet used it as i will only be going for my next dye session on April 19th.  once i have the color done i will then use this product. until then you will just have to wait for my update review on how it is working.
