PROBLEM TO BE SOLVED: To provide a composition for dyeing a keratin fiber, containing a new oxidation base material which has a toxicity profile better than those of para-phenylenediamine and para-tolylenediamine and simultaneously furnishes the hair with excellent characteristics regarding color intensity, kinds of color tones, uniformity of color, and fixity of the color against external action. SOLUTION: This composition for dyeing the keratin fiber, especially, the human keratin fiber including the hair, is prepared so that at least one para-phenylenediamine derivative which is substituted by a diazacyclohexane or diazacycloheptane ring and in which nitrogen in the 4-position forms a quaternary ammonium is contained in the composition as the oxidation base material.
