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

Using a toner in hair color primarily serves to adjust the tone of the hair color. After the initial hair coloring process, the underlying pigments can sometimes lead to unwanted hues, particularly if the hair has been lightened. Toners help to refine these tones, providing a more balanced and desirable color result.

For instance, if the hair turns out too brassy or warm after lightening, a toner with cooler undertones can neutralize those warmer shades. This process enhances the overall look of the color, ensuring that the final result aligns more closely with the client’s desired outcome.

While some toners can also work to remove specific unwanted hues like yellow tones, their main function is more about tonal correction and achieving the specific shade that is being sought after. Therefore, toners play a crucial role in the coloring process, allowing stylists to create customized and professional results.
