What is the function of toners in hair coloring?

Toners play a critical role in hair coloring by neutralizing unwanted hues and enhancing specific tones. When hair is lightened, it often reveals underlying pigments that may not be desirable, such as brassy or yellow tones. Toners, which can come in various shades, are specifically formulated to counteract these unwanted colors. For instance, a violet toner can help neutralize yellow tones, while a blue toner can counteract orange hues.

In addition to correcting unwanted tones, toners can also enhance the desired color. For example, a toner can intensify the richness of a shade, providing more depth and dimension to the hair color. This is particularly important for achieving a polished and professional finish in hair coloring.

The other functions listed are not related to the primary role of toners. Lightening hair, adding shine, or promoting hair growth are functions associated with different products or procedures in hair care. Therefore, understanding toners’ specific function in color correction and enhancement is crucial for effective hair coloring techniques.
