The system includes a container holding the hair dye and a comb-shaped applicator mounted on the container. ## Claims ### Claim 1 An air oxidation hair dye application system comprising: a container, an inside of which consists of walls surrounding an air oxidation hair dye composition contained in the container; and an applicator in a form of a comb having comb teeth, which projects from a base, mounted directly on the container, wherein the applicator is in fluid communication with the inside of the container and is capable of receiving the air oxidation hair dye composition from the container, and wherein an inside of the applicator consists of: a passage in the base; an internal manifold, which is a space surrounded by walls, that is in fluid communication with the inside of the container through the passage in the base and that receives the air oxidation hair dye composition from the container; and a plurality of openings exposed to air, which are in fluid communication with the space of the manifold, which are between adjacent said comb teeth, and through which the air oxidation hair dye composition is dispensed from the applicator. ### Claim 2 (depends on 1) The system according to claim 1, wherein the applicator is detachably mounted on the container. ### Claim 3 (depends on 2) The system according to claim 2, wherein the applicator is detachably mounted on the container via a thread. ### Claim 4 (depends on 1) The system according to claim 1, wherein the comb is formed with a flat surface that is parallel to a longitudinal axis of the applicator and substantially perpendicular to both opposing outer side surfaces of each comb tooth, and wherein the openings project through the flat surface. ### Claim 5 (depends on 4) The system according to claim 4, wherein the opposing outer side surfaces slope outwardly and toward a back of the applicator, so that a combined surface between adjacent comb teeth is trapezoidal in a cross-section taken perpendicular to the longitudinal axis of the applicator. ### Claim 6 (depends on 1) The system according to claim 1, wherein the openings are substantially circular and have a diameter from about 1.3 mm to about 1.9 mm. ### Claim 7 (depends on 1) The system according to claim 1, wherein each of the openings has the same diameter. ### Claim 8 (depends on 1) The system according to claim 1, wherein the container is a tube. ### Claim 9 (depends on 1) The system according to claim 1, wherein the openings are along a longitudinal axis of the applicator. ### Claim 10 (depends on 1) The system according to claim 1, wherein inner ends of the comb teeth project into the internal manifold. ### Claim 11 (depends on 1) The system according to claim 1, wherein an upper portion of the container is inside the passage. ### Claim 12 (depends on 1) A method for coloring hair comprising applying to the hair, from the air oxidation hair dye application system according to claim 1, the air oxidation hair dye composition through the openings in the applicator. ### Claim 13 (depends on 12) The method according to claim 12, further comprising combing the air oxidation hair dye composition through the hair using the applicator. ### Claim 14 (depends on 12) The method according to claim 12, further comprising combing the hair with the applicator while performing the applying of the air oxidation hair dye composition to the hair through the openings in the applicator. ### Claim 15 An air oxidation hair dye application system kit comprising: a container, an inside of which consists of walls surrounding an air oxidation hair dye composition contained in the container, the container covered with at least one of a cap and a seal; and an applicator in a form of a comb having comb teeth, which projects from a base, configured to be mountable directly on the container after removal of the at least one of the cap and the seal, wherein an inside of the applicator consists of: a passage in the base; an internal manifold, which is a space surrounded by walls, that is in fluid communication with the inside of the container through the passage in the base and is capable of receiving the air oxidation hair dye composition from the container when the applicator is mounted on the container; and a plurality of openings exposed to air between adjacent said comb teeth through which the air oxidation hair dye composition is dispensed from the applicator, and the openings are in fluid communication with the inside of the container when the applicator is mounted on the container. ### Claim 16 (depends on 15) The kit according to claim 15, wherein the applicator is detachably mountable on the container. ### Claim 17 (depends on 16) The kit according to claim 16, wherein the applicator is detachably mountable on the container via a thread. ### Claim 18 (depends on 15) The kit according to claim 15, wherein the comb is formed with a flat surface that is parallel to a longitudinal axis of the applicator and substantially perpendicular to both opposing outer side surfaces of each comb tooth, and wherein the openings project through the flat surface. ### Claim 19 (depends on 18) The kit according to claim 18, wherein the opposing outer side surfaces slope outwardly and toward a back of the applicator, so that a combined surface between adjacent comb teeth is trapezoidal in a cross-section taken perpendicular to the longitudinal axis of the applicator. ### Claim 20 (depends on 15) The kit according to claim 15, wherein the openings are substantially circular and have a diameter from about 1.3 mm to about 1.9 mm. ### Claim 21 (depends on 15) The kit according to claim 15, wherein each of the openings has the same diameter. ### Claim 22 (depends on 15) The kit according to claim 15, wherein the container is a tube. ### Claim 23 (depends on 15) The kit according to claim 15, wherein the openings are along a longitudinal axis of the applicator. ### Claim 24 (depends on 15) The kit according to claim 15, wherein inner ends of the comb teeth project into the internal manifold. ### Claim 25 (depends on 15) The kit according to claim 15, wherein the applicator is detachably mountable on the container such that an upper portion of the container is inside the passage. ### Claim 26 (depends on 15) A method for coloring hair comprising: providing the air oxidation hair dye application system kit according to claim 15; mounting the applicator on the container; and applying the air oxidation hair dye composition to the hair through the openings in the applicator. ### Claim 27 (depends on 26) The method according to claim 26, further comprising combing the air oxidation hair dye composition through the hair using the applicator. ### Claim 28 (depends on 26) The method according to claim 26, further comprising combing the hair with the applicator while performing the applying of the air oxidation hair dye composition to the hair through the openings in the applicator.
