Using a toner after coloring hair serves the primary purpose of adjusting the color tone to achieve the desired shade. When hair is colored, especially lightened, it can sometimes display unwanted undertones, such as yellow or brassy hues. A toner contains pigments that help neutralize these unwanted tones, allowing for a more balanced and harmonious color result.

For example, if the hair has a yellow undertone after bleaching, a purple toner can be applied to counteract that yellow, leading to a cooler, more ash-like finish. This step is particularly important in achieving specific color results like platinum blonde or cool brown shades. Toners can also enhance and enrich the overall color and provide a glossy finish, making them an essential part of the hair coloring process.
