Toning shampoos get rid of unwanted yellow, orange, or brassy tones on permanent hair color, natural hair color, highlights, and gray hair. Toning shampoos also helps reduce color fading and enhance hair color.
Purple shampoo is a toning shampoo that uses the color purple to directly brighten up the yellows and brass of dull blonde hair. If you have blonde hair or have highlights on darker hair, you may see the unwanted yellow or orange hues. Using a purple shampoo helps neutralize yellow or copper / red reflections, and keep your color consistent and vibrant.
