What is the main purpose of using a hair toner?

The main purpose of using a hair toner is to correct or enhance the color of the hair. Toners are specifically designed to adjust the undertones of hair after the bleaching or coloring process. They can neutralize unwanted brassy or yellow shades, giving the hair a more desirable hue. This is often crucial in achieving the desired final color, particularly for blonde shades, where the goal is to create cool or ashy tones instead of warm or golden ones.

While lightening hair strands and removing gray hair are important aspects of hair coloring, they are achieved through different processes and products, such as bleach or hair dye specifically formulated for gray coverage. Adding volume to the hair is generally achieved through styling techniques or volumizing products rather than the use of toner. Toners focus on the color aspect, making them essential for achieving the right look after a coloring treatment.
