Abstract
A method for color-revitalizing a color tone of hair that involves applying a color-revitalizing composition to hair previously dyed with an oxidative hair dye composition. The color-revitalizing composition, which has a color determined by the color of the oxidative hair dye composition and contains at least one direct dye, revitalizes the color tone originally obtained by after dyeing with the oxidative hair dye composition.
