Which hair color product is often used to neutralize unwanted brassy tones?

Hair toner is specifically designed to neutralize unwanted brassy tones in the hair, especially after lightening processes. Brassy tones typically appear as warm, yellow, or orange hues that result from the underlying pigment being exposed during hair lightening. Toners contain pigments that can counteract these unwanted shades; for example, purple or blue toners are commonly used to cancel out yellow or orange tones, respectively.

Unlike permanent dyes, which are used to achieve a more lasting color change, toners usually offer a semi-permanent solution that can adjust the overall appearance of the hair color without creating a significant lightening effect. Highlift color may lighten hair while depositing color but is not specifically formulated to neutralize brassy tones. Color removers are used to strip away color from the hair rather than to fine-tune or adjust the existing shade. Therefore, hair toner is the ideal product for achieving the desired cool or neutral tones after lightening hair.
