Abstract
Abstract This invention is a composition useful for dyeing keratinous fiber blond without using o-, m- or p-phenylenediamine, 2,4-diaminoanisole or nitro compounds. The composition consists essentially of m-aminophenol, p-aminophenol, p-methylaminophenol or a suitable acid addition salt thereof, a suitable modifier, a suitable coupler and a suitable base. This composition is combined with an oxidizing agent before contacting the hair to dye hair blond.
