Hairstylists choose a toner that is on the opposite side of the color wheel from the unwanted tone. If your hair color is too red, a green toner is used; if your hair is too orange a blue toner is used; and if your hair color is too yellow, a purple toner will neutralize the unwanted yellow tone. Toner can last an average of 4 to 8 weeks, depending on how well you take care of your hair color investment. Some toners last longer. When toner fades away, lighter warmer color is often exposed. Toner can be reapplied at the salon when faded, if desired.
