Applying a toner is the best way to neutralize unwanted tones after lightening hair because it is specifically designed to adjust the color of the hair. When hair is lightened, it can often reveal underlying colors, such as brassy yellows or oranges. Toners contain color pigments that counteract these unwanted hues. For example, a purple toner can neutralize yellow tones, while a blue toner can address orange tones.

In contrast, using a conditioner may help with moisture and manageability but does not change the color of the hair. A deep treatment similarly focuses on enhancing hair health and repairing damage but will not affect the unwanted brassiness. Rinsing with cold water can help to close the hair cuticle for added shine and smoothness, but it is not effective for altering the hair color.
