PROBLEM TO BE SOLVED: To substantially reduce the volume and weight of the container of a hair dye first agent which is used in large quantity in a beauty salon; to reduce a storage space of the hair dye first agent; and to substantially reduce the disposal amount of an aluminum tube discarded after use. SOLUTION: The hair dye first agent prepared by simultaneously blending ammonia in an amount of 2.5-5.6% and ammonium bicarbonate in an amount of 2-5% is mixed, as an alkali agent, with a hair dye second agent including hydrogen peroxide in an amount of 6% or lower, in a weight ratio of the former to the latter of 1:4 to 1:8, and then the resultant mixture is used as a hair dye. The hair dye first agent composition in an amount of 13-25 g is filled into a small-sized aluminum tube which has an interior content of 15-30 mL and of which the inner surface is coated with epoxy phenol. The used amount per person of the hair dye first agent is reduced from one third to one fifth of the conventional used amount while maintaining and improving the capability of the hair dye, thus achieving the miniaturization of a container, the reduction of storage space of a beauty salon, and the reduction of the amount of trash.
