A composition for the oxidative dyeing comprising gallic acid or gallate derivative is provided to minimize hair damage, promote hair decoloration and dye penetration into the hair, and reduce non-uniformed hair dyeing caused by application time difference of dyeing. The composition for the oxidative dyeing containing a first reagent with an oxidative dye precursor and a coupler, and a second reagent with an oxidizing agent comprises 0.01-5 wt.% of the gallic acid or gallate derivatives represented by the formula(1), wherein R is hydrogen or C1-22 linear or branched alkyl group as an antioxidant in the first reagent.
