A two-stage treatment process suitable for the permanent deformation and/or shaping of keratinous substances and, in particular, the hair includes the application of a reducing composition containing, in addition to a reducing agent, an organic absorbing agent followed, after an optional rinsing, by the application of a neutralizing composition and by the rinsing of the keratinous substances thus treated.

Process for the permanent deformation of keratinous substances employing an organic absorbing agent

The invention concerns an agent for use as reducing agent in a method for permanent hair setting, comprising: a first constituent consisting of a powder composition, comprising at least an agent for reducing solid keratin or adsorbed on a solid; a second constituent consisting of aqueous liquid composition not containing a keratin reducing agent, the different constituents designed to be mixed with each other when used to obtain a reducing composition designed to be applied on the hair for reducing the sulphur bonds thereof.

Reducing agent with several constituents comprising at least a composition in powder form containing an agent for reducing hair sulphur bonds and method for permanent setting of keratin fibres
