  • oxidation bases such as ortho- or para- phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds.
  • oxidation bases are generally combined with couplers.
  • couplers are colorless or weakly colored compounds, which, when combined with oxidizing products, may give rise to colored compounds by a process of oxidative condensation. This type of oxidation dyeing makes it possible to obtain“permanent” colorings.
  • dye keratin fibers and in particular human hair with dye compositions containing direct dyes.
  • the standard dyes that are used are, in particular, dyes of the nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane type, or natural dyes. These dyes are colored or coloring molecules that have affinity for keratin fibers.
  • compositions containing one or more direct dyes are applied to the keratin fibers for a time necessary to obtain the desired coloring, and are then rinsed out.
  • the resulting colorings are particularly chromatic colorings, but are, however, temporary or semi-permanent since the nature of the interactions that bind the direct dyes to the keratin fiber and their desorption from the surface and/or the core of the fiber are responsible for their weak dyeing power and their poor persistence with respect to washing or perspiration.
  • Direct dyeing products notably make it possible to modify the natural color of the hair, or to cover white hairs.
  • the intensity of the coloring obtained by using these products is occasionally judged as being too weak relative to the expectations of users on the day of application.
