A first interchangeable component has a roller ball and is ideal for use when distribution of hair dye along a part at the root of the hair is desired. A second interchangeable component has a plurality of flexible brushes, and is ideal for distribution of hair dye throughout the hair and along the hair shafts. A third interchangeable component has a plurality of rigid combs, and is ideal for overall distribution of hair dye in coarse or thick hair. Both second and third interchangeable components contain a moveable disc which allows a user to control the rate of discharge of hair dye from the hair dye applicator. The hair dye applicator of the present invention has a lid that may be utilized to prevent spillage and to slow oxidation of unused hair dye which may be needed throughout the hair coloring process.
