To facilitate hair dyeing work by putting two kinds of hair dyes within a container just before dyeing hair, mix-stirring it to make a hair dyeing liquid and applying hair dye to the base part of hair directly from the nozzle tip of a manual injection device assembled to the container.

A lower barrel part 1b is removed from the upper barrel part 1a of the container 1, the two kinds of hair dyes are put into the part 1a at a prescribed ratio and the parts 1a and 1b are connected. By shaking the hair dye with the container 1, a stirring weight 11 turns around the container bottom part 4 to generate stirring operation with a sucking tube 10 to mix-stir both hair dyes to make the hair dyeing liquid. At the time of hair dyeing work, the injecting device main body 2a of a manual injector 2 is held by a hand, a pointing finger, middle finger, etc., and put on a lever 2b and the nozzle tip 7a is put into hair to fit on a head skin. Then, at the time of moving the tip 7a in the hair in a scheduled direction while pull-operating the lever 2b from this state, the hair dyeing liquid within the container 1 is discharged from the liquid discharging exit of the tip 7a under a nearly fixed discharging pressure to be applied to the base part of the hair.
