What is the main purpose of hair toners?

The main purpose of hair toners is to adjust the tone of colored hair. Toners are specifically formulated to neutralize unwanted undertones that can appear after hair has been dyed or bleached. For example, if someone has lightened their hair and it ends up with a brassy or yellow tone, a toner can help to create a cooler, more desirable shade by counteracting those unwanted tones.

Toners usually contain color pigments that can enhance or modify the existing base color, making the final result more vibrant and natural looking. They are often used after the initial hair coloring process to refine the overall color and improve the hair's appearance. This application highlights the importance of toners in achieving the desired hair color and ensuring that it looks polished.

While other options touch upon aspects of hair care, they do not accurately reflect the primary function of toners. For instance, altering hair color completely is the role of permanent or semi-permanent dyes, and conditioning agents are specifically aimed at moisturizing and repairing hair rather than color adjustment. Additionally, product buildup removal requires cleansing agents rather than toners, which do not serve that specific purpose.
