Purple shampoos, like those within the Matrix Total Results So Silver range, are designed to neutralize unwanted brassy and yellow tones in lightened, gray, or white hair. These shampoos contain violet pigments that deposit onto the hair shaft, counteracting the yellow/orange hues that can develop due to oxidation, mineral deposits in water, or the natural lightening process. The effectiveness of such a product depends on factors like hair porosity, initial tone, and frequency of use. An example outcome would be a cooler, brighter blonde or a more vibrant, clear gray.
Maintaining the desired tone in light or gray hair can be challenging. These shampoos offer a convenient and cost-effective way to control brassiness and maintain a cooler, more polished look at home. Historically, colorists would use toners in-salon for this purpose, making frequent visits necessary. The advent of purple shampoos provided a practical solution for extending the life of professional color treatments and managing tonal shifts between salon appointments.
