The main function of a toner in hair coloring is to neutralize unwanted tones. Toners are specifically formulated to adjust the final color of the hair after it has been bleached or colored, correcting any undesirable hues that may result from the initial hair coloring process. For instance, after bleaching, hair can develop yellow or brassy tones; a toner with purple or blue pigments can counteract these warm tones, leading to a cooler, more balanced color.

This process is particularly important in achieving the desired shade, especially for blondes or pastel colors where precision in toning can dramatically affect the final appearance. While lightening and darkening hair are processes typically handled during the initial coloring stage, toners specifically target tonal adjustments rather than altering the lightness or darkness of the base color. Volumizing is also unrelated to toners, as it pertains to adding body and fullness to the hair rather than affecting its color. Overall, toners are an essential step in the hair coloring process, focused solely on creating the most aesthetically pleasing and balanced color result.
