The primary purpose of a toner in hair coloring is to neutralize unwanted warmth. When hair is lightened, particularly during the bleaching process, it can develop unwanted undertones, typically brassy or yellow hues. Toners are specifically formulated to counteract these warm tones, allowing for a more balanced and desirable hair color.

Tonners often contain pigments that can cancel out unwanted shades; for example, violet toners can neutralize yellow tones, while blue toners can help mitigate orange tones. This corrective process is essential in achieving the desired final color result after the initial lightening.

Understanding this purpose helps stylists select the appropriate toner based on the client's desired outcome and the existing color of the hair. This knowledge is crucial in providing a professional and satisfying service in hair coloring.
