Abstract: A cartridge for use in a hair dye dispenser includes a dispensing container for containing and dispensing the hair dye, the dispensing container having a base and at least one side wall sealingly attached to or integrally formed with the base so as to define an internal volume of the dispensing container. The base has a lower surface that is formed with a number of projecting tines and at least one dispensing aperture. A piston is configured to fit closely in sliding abutment with the at least one side wall so as to be sealingly slidable towards the base. The dispensing container and the piston are formed from polymer material, the piston being pressure-fitted within the dispensing container so as to define an initial position of the piston.
