Abstract
Disclosed herein is a process for dyeing keratin fibers such as the hair, comprising, in order, applying to the scalp a composition comprising at least one polyoxyethylenated sorbitan ester having less than or equal to 10 moles of ethylene oxide, and subsequently applying to the keratin fibers a dye composition comprising at least one dye precursor in a suitable medium. Such a process may make it possible to conserve strong a coloration while at the same time limiting the discomfort that may be experienced on the scalp at the time of application of the dye composition or after this application.
