What Does Purple Shampoo Do?

Purple shampoo is specially formulated to neutralize unwanted yellow or brassy tones in blonde, silver, or gray hair. The violet pigments in the shampoo work as a color corrector — because purple is opposite to yellow on the color wheel, it cancels out warm undertones and restores a cooler, brighter shade.

Using purple shampoo regularly helps keep blonde and lightened hair looking fresh, vibrant, and salon-toned between color appointments. It can also enhance natural gray or white hair, giving it a cleaner and more luminous finish.
