Abstract
The invention relates to a cosmetic composition comprising one or more polymers comprising one or more cationic or quaternized acrylamide and/or methacrylamide unit(s); a particular oil-in-water-type silicone emulsion; one or more surfactants; and optionally one or more direct dye(s)/pigment(s). The invention also relates a cosmetic process for washing and/or condition keratin fibres using said cosmetic composition.
