The invention relates to a process for densification of the hair, comprising a stage of application to the hair and/or the scalp of a composition consisting, in a physiologically acceptable medium, of an effective quantity of at least one precursor of densification chosen from among the compounds comprising at least one aromatic cycle having at least two hydroxyl groups borne by two consecutive carbon atoms of the aromatic cycle and an effective quantity of a catalytic system comprising one first constituent chosen from among the salts and oxides of Mn(II) and/or Zn(II) and mixtures thereof and a second constituent chosen from among the alkaline hydrogenocarbonates, the alkaline-earth hydrogenocarbonates and mixtures thereof. It also relates to a composition containing, in a physiologically acceptable medium, the said precursor of densification and catalytic system, combined with an active principle promoting the regrowth of hair, with delayed effect or for the dressing of the hair.
A composition for care of the human keratinous fibers and/or the skin from which these fibers emerge, comprising, in a physiologically acceptable medium, a) an effective quantity of at least one precursor of densification chosen from among the compounds comprising at least one aromatic cycle having at least two hydroxyl groups (OH) borne by two consecutive atoms of the aromatic cycle, b) an effective quantity of a catalytic system comprising a first constituent chosen from among the salts and oxides of Mn(II) and/or Zn(II) and mixtures thereof and a second constituent chosen from among the alkaline hydrogenocarbonates, the alkaline-earth hydrogenocarbonates and mixtures thereof, and c) an effective quantity of at least one active principle with delayed effect increasing hair density and/or promoting regrowth of the keratinous fibers, in particular of the hair, and/or limiting the loss of these fibers and in particular of the hair, the proportions of the first constituent and the second constituent being such that:
A process for densification of the human hair or for dressing of the hair, comprising applying to the hair and/or scalp a composition comprising, in a physiologically acceptable medium for topical application, an effective quantity of at least one precursor of densification, chosen from among the compounds comprising at least one aromatic cycle having at least two hydroxyl groups borne by two consecutive carbon atoms of the aromatic cycle, and an effective quantity of a catalytic system comprising a first constituent chosen from among the salts and oxides of Mn(II) and/or Zn(II) and mixtures thereof and a second constituent chosen from among the alkaline hydrogenocarbonates, the alkaline-earth hydrogenocarbonates and mixtures thereof, the proportions of the first and second constituents being such that:
