Toner plays a crucial role in the hair coloring process by neutralizing unwanted undertones that may arise after lightening the hair. When the hair is bleached or lightened, it can often develop unwanted tones, such as brassiness or excessive warmth. Toners are specially formulated to counteract these effects, using color theory principles where specific colors are used to neutralize hues opposite on the color wheel. For example, a blue or violet toner can effectively cancel out orange or yellow undertones, resulting in a more balanced and desirable hair color.

The other options do not accurately reflect the primary purpose of a toner. Lightening dark hair generally requires a bleaching process rather than toner, which is not meant for creating highlights directly but can enhance or refine them. Additionally, toners are not used to provide permanent color; instead, they often offer semi-permanent solutions aimed at refining or adjusting the color rather than changing it entirely.
