A toner is a hair color product used to neutralize unwanted tones and enhance desired tones in the hair. After lightening or coloring the hair, underlying pigments may be exposed. A toner is applied to the hair to counteract these tones and achieve a more balanced, natural-looking color. Toners come in various shades, including ash, silver, platinum, and pearl, and can be customized to complement different hair colors and undertones.
