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

1. To lighten the hair color

2. To adjust hair color by neutralizing unwanted tones

3. To add shine to the hair

4. To enhance the natural hair color

The correct answer is: To adjust hair color by neutralizing unwanted tones

The purpose of using a toner in hair coloring is to adjust the hair color by neutralizing unwanted tones. Toners are typically used after the bleaching process to refine and enhance the desired hair color, particularly when brassy or yellow tones are present. They contain color pigments that can counteract these unwanted hues, leading to a more balanced and aesthetically pleasing result. For example, if the hair appears too warm or has yellow undertones after bleaching, a purple toner can be applied to neutralize those tones, creating a cooler blonde shade. This adjustment is crucial for achieving specific hair color results, especially when aiming for shades like ash blonde or silver. In contrast, other options listed do not accurately describe the primary function of a toner. Lightening hair color is associated with bleaching agents rather than toners. Adding shine relates more to hair conditioners or serums, and enhancing natural hair color typically involves techniques like subtle highlights or gloss treatments rather than using a toner, which is specifically designed to modify existing color tones.
