What is the purpose of using a toner in hair coloring?

Using a toner in hair coloring serves the important purpose of correcting or enhancing hair color, particularly after the bleaching process. When hair is bleached, it often takes on unwanted underlying tones, such as brassiness or yellow hues. A toner can neutralize these tones and provide a more balanced and aesthetically pleasing color finish.

Tonerse typically contain colored pigments that can modify the hair's shade. For example, a purple toner can counteract yellow tones, while a blue toner can neutralize orange hues. This refinement of color allows for a customized look that aligns with the desired result after bleaching.

The other options do not accurately reflect the function of a toner. For instance, enhancing hair length pertains to hair treatments and extensions, not color correction. Stripping existing color is more aligned with color removers or specific lightening agents. Facilitating quicker drying does not relate to toners, as their primary role is in color adjustment rather than influencing drying times.
