To provide a hair dye kit which, when using a hair dye requiring an operation of repeating
discharge and application, achieves efficiency of the operation while reducing a burden on a user in
spite of a simple structure.SOLUTION: A composition for hair
dyeing or hair bleaching (A), a vessel (X) for filling the composition for hair
dyeing or hair bleaching (A) having a
discharge part (x1) and a vessel main body (x2), and a support (Y) for holding the vessel (X), wherein the vessel (X) is used in an upright or obliquely inverted state by holding the vessel (X) on the support (Y) with the
discharge part (x1) facing downward and the bottom surface of the vessel main body (x2) facing upward. A hair dye or
hair bleach kit, wherein the composition for hair
dyeing or hair bleaching (A) has a specific
viscosity, the discharge part (x1) has a
specific discharge port (x1 - 1), and the support (Y) has a specific mechanism for allowing the vessel (X) and the support (Y) to have a specific positional relationship at the
time of use.SELECTED DRAWING: None
