Abstract

Disclosed is a method of dyeing artificial hairs. The method includes increasing a temperature of a first dye mixture solution, primarily dyeing a bundle of artificial hairs after introducing the artificial hairs into a body, cleaning the body after drying the primarily-dyed artificial hairs, and moving up the artificial hairs while draining the first dye mixture solution, increasing a temperature of a second dye mixture solution composed by water and a dye representing another color by a hot water supply, and dyeing secondarily the artificial hairs by reversing the primarily-dyed artificial hairs, and slowly supplying a dye to the body to gradually increase the concentration of the second dye mixture solution. The artificial hairs are gradient-dyed in two colors or three colors to be dyed in various colors required by consumers. The time spent for a dyeing work is short, so the artificial hairs are dyed for a short time.
