Purple shampoo is specifically formulated to neutralize unwanted brassy tones in hair, particularly in blonde, gray, and silver hair. The product contains purple pigments that counteract the yellow hues often found in hair that has been lightened or highlighted. This color-correcting effect occurs because purple is opposite to yellow on the color wheel, allowing it to effectively balance and soften brassy tones when applied during regular washing.

The other types of products listed serve different purposes. Clarifying shampoo is designed to remove product buildup and clarify the hair, which does not directly address color correction. Moisturizing cream is intended to hydrate and soften hair, enhancing its texture but not impacting the color. Heat protectant spray is used to shield hair from damage caused by heat-styling tools and does not influence color tone. Hence, using purple shampoo is the most effective way to neutralize brassiness and achieve a more balanced, cool-toned hair color.
