Abstract: In a method for oxidatively dyeing hair, a pretreatment which comprises contacting hair with an aqueous solution of an effective amount of particular metal/chelate complexes followed by treatment with oxidative dye mixtures is disclosed. The process serves to conform the oxidative dyeing rate of virgin hair to that of the normally noncongruent rate of nonvirgin hair, so as to enhance the efficiency of the oxidative dyeing process, without reducing the intensity or variety of color available.
Abstract: A method of coloring hair in which there is applied to the hair a hair coloring preparation consisting essentially of a water based organic solvent free mixture of 0.01 to 10.0 percent by weight of a temporary dye color which is a water soluble acid dye, 0.1 to 10.0 percent by weight of a quaternary ammonium functional silane, the remainder of the mixture being water. The mixture is combed through the hair and the hair is allowed to dry without rinsing.
Abstract: A process for dyeing hair by preparing and thereafter applying to the hair an aqueous reaction medium comprising dopa and an oxidant, said aqueous reaction medium further containing at least one hair dyeing agent selected from the group consisting of primary intermediates and couplers and also containing a buffer to maintain the pH in the range from 6 to 10 during the reaction, and removing said aqueous reaction medium from the hair within about one hour following its preparation.
