The invention provides a color-deepening hair dyeing composition. The color-deepening hair dyeing composition comprises, by weight, 2-98 parts of hair dye, 1-99 parts of color deepening agent, 2-98 parts of cross-linking agent, 2-98 parts of emulsifying agent, 2-98 parts of dyeing auxiliary and 0.1-40 parts of pH (potential of hydrogen) conditioning agent, wherein the color deepening agent is selected from one or more of chitin, chitosan, gelatin, silicone oil and resin, the relative molecular mass of each of the chitin, the chitosan and the gelatin is smaller than 2.7x10 , and the refractive index of each of the silicone oil and the resin is smaller than 1.55. The color-deepening hair dyeing composition has the advantages that under the action of the color deepening agent, the cross-linking agent and the like, unsaturated color dyed by the natural hair dye can be deepened, and saturated deep color can be finally obtained, or use amount of the chemical hair dye can be decreased greatly; hair dyeing time can be shortened, hair dyeing temperature can be lowered, injuries to human bodies can be reduced relatively, dyefastness is enhanced, hair dyeing interval is prolonged, and times of hair dye repetition are decreased.
