The primary function of a hair toner is to change the undertone of hair color. After a hair lightening process, such as bleaching, the hair can often take on unwanted warm tones like yellow or orange. Toners are specifically formulated to neutralize these undesirable undertones, allowing for a more balanced and aesthetically pleasing hair color. By using various shades of toner, stylists can achieve the desired hue, whether that be a cooler ash tone or warmer shades.

While lightening hair color is an important part of the hair coloring process and can enhance vibrancy, it does not specifically address the underlying tones that toner is designed to correct. Likewise, even though moisturizing hair is essential for overall hair health, it is not the aim of toner. Straightening hair is also unrelated to the function of toner, as that pertains to altering the hair’s texture rather than its color. Thus, the distinctive role of a toner is clearly linked to adjusting the undertones in the hair color.
