Disclosed is a semi-permanent hair dyeing composition using a waterproof coating agent, in particular, a semi-permanent hair dyeing composition comprising a water-soluble dye, an acid dye, acrylate copolymer as a waterproof coating agent and N-methyl pyrrolidone as a solvent in a certain amount. The semi-permanent hair dyeing composition of the present invention has an advantage in that although the composition is not washed out after the application to the hair, the water-soluble dye fastened to the hair surface is not melted down by rainwater or sweat, and thereby, it can prevent skin and clothes from being contaminated with the dye.
