The primary purpose of using a toner in hair color treatment is to enhance underlying tones. Toners are specialized products that are applied to pre-lightened hair to adjust or refine the color, often neutralizing unwanted hues or adding vibrancy to the desired shades. For example, after bleaching, hair may develop unwanted yellow or orange tones; a toner can help to counteract these and achieve a more balanced, aesthetically pleasing color.

Additionally, toners can help in creating various shades by adding specific pigments, thus allowing for a customization of the final look. This is particularly important in achieving the perfect blonde, as toning can help transition between varying shades and create depth in the hair color.

While other options suggest functions related to lightening, removing color, or adding shine, these do not accurately reflect the role of a toner. Lightening is typically achieved through bleaching, and removing previous color often requires a color remover or corrective processes, while shine can be enhanced through different products like serums or finishing sprays rather than a toner.
