What is the function of a toner in hair coloring?

1. To enhance hair texture

2. To neutralize unwanted tones and enhance overall color

3. To add moisture to the hair

4. To remove hair color

The correct answer is: To neutralize unwanted tones and enhance overall color

The function of a toner in hair coloring is primarily to neutralize unwanted tones and enhance the overall color. After the initial hair coloring process, particularly when using lighteners, certain undertones can become apparent. These may include brassy or yellowish hues that are often undesirable. A toner, which is typically a demi-permanent or semi-permanent color, is applied to the hair to balance these tones and achieve a more desirable and polished finish. For instance, if the hair appears too yellow after bleaching, a purple toner may be used, as purple is opposite yellow on the color wheel and helps to neutralize those warm tones. Likewise, if the hair has an orange tint, blue toners are effective in correcting that issue. Additionally, toners can enhance the overall color by adding depth and dimension, allowing for a more sophisticated look that complements the individual's style. While enhancing hair texture and adding moisture to the hair are beneficial aspects of certain products or treatments, they are not the primary functions of a toner in the context of hair coloring. Similarly, removing hair color is a different process altogether, typically involving color removers or bleach rather than a toner.
