A two part aqueous composition for coloring and providing durable conditioning to human hair which forms a gel on mixing of an alkaline aqueous lotion first part having a pH of from about 7 to about 11 containing from about 0.005% by weight to about 5% by weight of at least one primary intermediate and at least one coupler for the formation of oxidation dyes, from about 0.1% to about 5% of a cationic polymer, from about 0.5% to about 15% by weight of an anionic or amphoteric surfactant or mixture thereof and at least 70% by weight water, and an aqueous developer second part having a pH of from about 2 to about 6 containing from about 0.5% by weight to about 40% by weight of a peroxide oxidizer and from about 0.1% by weight to about 20% by weight of an anionic polymer, the anionic polymer being characterized in that it is insoluble in the developer and dissolves in the gel which forms when the lotion and developer are mixed.

Two-part aqueous composition for coloring hair, which forms a gel on

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.

Process for simultaneously waving and coloring hair

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.

Neutralizing composition and method for hair waving and straightening

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.

Hair conditioning composition containing cationic polymer and amphoteric

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.

Hair waving or straightening process and product

Oxidation dye compositions particularly useful for dyeing human hair containing as the meta component compounds of the formula: ##STR1## or their non-toxic salts, wherein R is alkyl, hydroxyalkyl, phenylalkyl, phenylsulfonyls, alkylsulfonyls or cyanoalkyl.

Dyeing keratin fibers with 2-substituted m-toluenediamines

Compounds useful as hair dyes of the formula: ##STR1## in which R.sup.5 is OH, -NH(lower hydroxyalkyl), -N(lower hydroxyalkyl).sub.2 or -O lower alkyl.

Hydroxyalkyl-amino nitrodiphenylamine compounds useful as hair dyes

A hair dye composition comprising a fluid direct-dye hair dye vehicle suitable for application to human hair containing a tinctorially effective amount of a hair dye of formula: ##SPC1## In which:
