A purple shampoo is a shampoo with violet pigments that neutralize yellow and brassy tones in blonde, highlighted, gray, or white hair. It works on color theory: purple sits opposite yellow on the color wheel, so the two neutralize each other, leaving the color looking cooler and brighter.
The pigments sit on the hair's surface and wash out over time, so the shampoo should be used regularly to maintain the effect. For orange tones in darker hair, the equivalent is a blue shampoo.
