The Silver Illuminating Shampoo is a deep cleansing shampoo that contains a deep purple pigment which tones and neutralizes orangey and brassy yellow tones. This shampoo neutralizes deep yellow contrasts in blonde, gray, and/or silver hair to help maintain a vibrant color. The Silver Illuminating Shampoo can help you achieve any tone from a honey-blonde to a cool silver shade, depending on the time lapse of its application. Unlike most “purple shampoos,” the Silver Illuminating Shampoo does not strip hair from its natural oils which aid in preventing dryness and protecting hair fibers.
