| 摘要 |
A process for dyeing keratinous fibers employs a dye composition containing an oxidation base selected from a paraphenylenediamine, an N,N'-diphenylalkylene diamine, a para-aminophenol, an ortho-aminophenol, an ortho-phenylenediamine or a heterocyclic oxidation base, in combination with iodide ions. The application of this dyeing composition to the keratinous fibers is preceded or followed by the application to the fibers of a composition containing hydrogen peroxide.
