Abstract: An improved process for the treatment of human keratinous fibers, in particular hair, with a view especially to decreasing and/or preventing damage to the latter by bringing, for a period not exceeding 2 minutes, a gas containing steam and whose temperature is at least 75.degree. C., into contact with human keratinous fibers to which there has been applied a composition containing at least one amide compound which has at least one fatty chain with the exception of coprah diethanolamide and subsequently cooling the fibers thus treated. This process improves the binding of the amide on and/or in the hair, and results in an improvement in the cosmetic properties, in particular softness and smoothness.

Abstract: A process for directly dyeing keratinous fibres, characterized in that it comprises contacting the fibres with a composition containing at least one direct dye having at least one sulphonic functional group and with a gas containing water vapor, the temperature of the gas being at least 75.degree. C. and the contact time between the gas and the fibres to be dyed not exceeding two minutes. This process makes it possible to obtain excellent dyeing results in extremely restricted time periods and without risk of substantially staining the skin or the scalp.

Abstract: A cosmetic composition for setting the hair contains, in an aqueous or weakly hydroalcoholic medium, (a) 0.5 to 40 percent by weight relative to the total weight of the composition of a hydrodispersible polycondensate having sulfonate functions, and (b) 0.5 to 15 percent by weight relative to the total weight of the composition, of a hydrosoluble copolymer having at the same time patterns derived from vinyl acetate, at least one monomer having a neutralized carboxylic acid function and at least one monomer having cyclic ester function, the total neutralization amount of the said copolymer being greater than 80 percent. This composition exhibits excellent setting power while being removed very satisfactorily by washing with a shampoo.

Abstract: A process for the bleaching of keratinous fibres, in particular human keratinous fibres, characterized in that it comprises contacting the fibres with a bleaching composition containing at least one oxidizing agent and with a gas containing water vapour, the temperature of the gas being at least 75.degree. C. and the contact time between the gas and the fibres to be bleached not exceeding ten minutes. The rapid bleaching is obtained without generating substantial reddish-brown glints.

Abstract: The invention relates to a treatment process for obtaining a non-permanent reshaping of keratinous fibres, especially the setting of hair, comprising the steps of (i) contacting the fibres, which are maintained under mechanical tension and to which has been applied a composition containing at least one oil, with a gas containing water vapour, the gas having a temperature of at least 75.degree. C., for a time not exceeding 2 minutes to non-permanently reshape the fibres, (ii) cooling the fibres thus contacted, and lastly (iii) removing the mechanical tension which was applied to the fibres, in order to obtain fibres having long-lasting, attractive curls and exceptional cosmetic properties of softness and smoothness.

Abstract: A process for the oxidation dyeing of keratinous fibers, characterized in that it comprises contacting the fibers, in the presence of an oxidizing agent, with a composition containing at least one oxidation dye and with a gas containing water vapor, the temperature of the gas being at least 75.degree. C., preferably greater than 75.degree. C., and the contact time not exceeding two minutes, preferably less than two minutes. The hair is dyed uniformly over the whole head of hair, from the roots to the ends, regardless of the condition of the hair.
