Abstract: A process for dyeing hair by preparing and thereafter applying to the hair an aqueous reaction medium comprising dopa and an oxidant selected from ferricyanide and permanganate salts, said aqueous reaction medium further 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

Abstract: A hair dyeing process which comprises of steps of contacting the hair to be dyed with an aqueous solution of a metal salt that promotes melanogenses in air. Before or after the aforementioned step contacting the hair with a solution of 5,6-dihydroxyindole, rinsing the hair between the two contacting steps, maintaining the contact with the second-used solution until a desired darker color is obtained, rinsing or shampooing the hair, then contacting the hair with a solution of hydrogen peroxide until the desired color shade is obtained, and then again rinsing the hair.

Abstract: A process for simultaneously cold waving and coloring hair in which the neutralization of the hair waving composition is accomplished in two stages, the second stage of which involves the use of a neutralizing composition containing a hair dye.

Abstract: A composition for coloring skin comprising a carrier containing an alcohol component consisting of an aromatic alcohol, an aliphatic alcohol or mixtures thereof and certain certified acid dyes, said composition having an acid pH equal to or less than 4.

Abstract: A process for coloring and/or conditioning hair using modified primary intermediates and/or a modified coupler containing a hydrophobic group or a group containing a cationic site amenable to reaction with an anionic surfactant; novel modified primary intermediates and modified couplers also being disclosed as well as novel synthetic methods for making these compounds.

Abstract: A process and composition for dyeing hair involving the precipitation of an anionic polymeric dye by means of a cationic polymer preferably in the presence of a surfactant and particularly an amphoteric surfactant.

Abstract: A process for coloring hair in which a functional metal ion and aminoalkyl or aminohydroxyalkyl catechols are used in combination or applied sequentially to dye the hair rapidly.

Abstract: A neutralizing and conditioning composition for the hair includes an oxidizing agent such as hydrogen peroxide and an amino-functional polymeric silicone additive for imparting durable conditioning benefits to the hair. A method is provided for neutralizing and conditioning hair which has been subjected to a waving or straightening treatment with keratin reducing agent by applying the new composition to the treated hair.

Abstract: A process for dyeing keratinaceous substances such as hair, wool, skin etc., which comprises contacting the same with a composition containing an aromatic azide or azidoindole component having the formula ##STR1## wherein X is hydroxyl, alkoxyl, NR'R", in which R' and R" are independently of each other hydrogen, alkyl or hydroxyalkyl, and if R' is H or alkyl, then R" can be further carbamylalkyl, mesylaminoalkyl, acylaminoalkyl, sulfoalkyl, piperidinoalkyl or morpholinoalkyl, R' and R" can also form with the nitrogen atom to which they are attached a piperidine or morpholine ring, R is hydrogen, alkyl, hydroxyalkyl, halogen, nitro, cyano or alkoxyl, W, Y and Z are independently of each other H or R', wherein all of the aforementioned alkyl moieties can have between 1 and 8 carbon atoms, and then exposing the contacted keratinaceous material to a suitable light source for sufficient time to develop the color.

Abstract: An aqueous composition useful for conditioning hair consisting essentially of an aqueous carrier containing a cationic polymer product and amphoteric surfactant product in specified proportions and having a pH in the range of from about 1 to about 6.

Abstract: The invention concerns a process wherein a premoistened tissue is applied to the ends of a strand of hair, the strand is wound around a preheated curler and left thereon until substantially dry. The tissue is saturated with an aqueous solutionwhich may contain the water solvent alone, or also dissolved in the water a hair conditioner and/or a setting lotion.

Abstract: Method and composition for modifying moisture retention of hair and thus improving its settability which comprises applying to hair an aqueous solution containing a heximinium salt and a resorcinol under conditions promoting in situ polymerization.

Abstract: A process and composition for coloring human hair on the head with pigments that employ a dispersion of pigment or pigments in an aqueous alcoholic liquid medium that contains a cationic polymer that is compatible with the aqueous alcoholic medium.

Abstract: A hair conditioning composition containing an amino functional silicone polymer in aqueous emulsion such as amodimethicone, and an effective amount for increasing the combability of hair of a cationic surfactant-emulsifier containing at least one long chain fatty acid residue which has between 12 and 18 carbon atoms, and an effective amount for increasing the combability of hair and for improving the durability of the conditioning effect of at least one cationic polymer in an aqueous carrier. The process of the invention involves the application of the aforementioned conditioning composition before or after shampooing whereby the durability of the conditioning effect is further enhanced.

Abstract: A process for waving or straightening hair in which an anionic surfactant is added to the hair reducing solution and the hair is treated either during a prewetting step or during neutralization, or both with a cationic polymer product which forms a substantially water insoluble complex with the anionic surfactant in the presence of hair.
