Abstract
In one embodiment, the disclosure relates to a composition for dyeing keratin fibres, for example, human keratin fibres such as the hair, comprising at least one para-phenylenediamine derivative substituted with a diazacyclohexane or diazacycloheptane ring, the nitrogen in position 4 of which is a quaternary ammonium. The present disclosure may make it possible, for example, to obtain at least one of chromatic, strong, relatively unselective, fast coloration of keratin fibres.
