Abstract
A process for manufacturing colored hair is disclosed. This process comprises the steps of applying a color sizing agent to hair material, semi-drying the color sizing agent applied to the hair material, winding a vapor feeding member comprised of a net member and a moisture-containing member around an area of the hair material where the color sizing agent is applied, winding an evaporation adjusting member for adjusting the quantity of evaporation of the moisture around the vapor feeding member from outside thereof, and permeating and fixing the color sizing agent to the applied area of the hair material by heating the vapor feeding member, thereby, hair at least partly applied with a desired color or color shade is obtained. A colored hair obtained by the above process is also disclosed.
