A toner serves a specific purpose in the hair coloring process, primarily focusing on neutralizing unwanted undertones that may arise after bleaching or coloring hair. When lightening hair, certain brassy or yellow tones can develop, particularly in blonde shades. Toners work by using color theory to counteract these undesired hues; for instance, a purple toner can neutralize yellow tones, resulting in a more balanced and polished finish.

While enhancing natural color, hydrating hair, and preparing hair for dyeing are important aspects of hair care and coloring, they do not directly address the primary function of a toner. Enhancing natural color typically refers to emphasizing the existing shades rather than correcting tones. Hydration is crucial for maintaining hair health but is accomplished through conditioning treatments rather than toners. Lastly, preparation for dyeing usually involves steps like cleansing and using appropriate treatments to ensure the hair is in optimal condition for color application, rather than serving the specific corrective role that toners provide.
