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

The primary purpose of a toner in hair coloring is to achieve pale and delicate colors on prelightened hair. Toners are specifically formulated to refine and adjust the tone of bleached or lightened hair, neutralizing any unwanted brassiness or warmth that may arise from the lightening process. After the hair has been prelightened to a lighter shade, using a toner allows you to put a subtle hue over the hair. This can result in soft, pastel-like colors or achieve the desired cool or warm tones, depending on the specific formula of the toner used.

Toners typically contain color pigments that provide a final touch to the hair color process, ensuring that the end result is visually appealing and enhances the overall look of the hair. They are essential for anyone aiming for a specific shade of blonde or for achieving a balanced color that avoids the yellow or orange undertones that can be present in newly lightened hair.
