发明名称 Brush and method for hair treatment using bristle arrays of different densities and materials
摘要 A device for applying a hair treatment solution, such as dye, includes a body having a head and a handle extending from the head. Three arrays of bristles extend from a major surface of the head in a direction perpendicular to the direction of the handle. A center array of bristles has a high bristle density and functions as an absorbent structure for retaining and applying a treatment solution. The end arrays sandwich the center array and have a low bristle density. The bristles of the end arrays have a greater rigidity than those of the center array. The device is used to simultaneously comb hair on one side of a hair partition, apply treatment solution to the partition, spread the treatment solution, and repartition the hair for a subsequent application of treatment solution.
