A method for dyeing hair using hydrophobic film-forming polymer is provided to form the color coating for preserving physical quality of keratin fiber. A method for dyeing hair comprises: a step of applying a composition containing 0.1 weight%-40 weight% of hydrophobic film-forming polymer, 1 weight%-40 weight% of pigment and 0.1 weight%-95 weight% of volatile solvent on the hair; and a step of heating the hair over 40 °C. The hydrophobic film-forming polymer is polyurethanes, polyacrylate, vinylester copolymer, silicon resin, the polyurea/polyurethanes silicon based material, copolymers of silicon resin and dimethiconol material or reactive silicone. The volatile solvent is water, ethanol, isopropanol, acetone, isodecane, decamethylcyclopentasiloxane, octamethyltrisiloxane, or decamethyltetrasiloxane. The pigment is a nacre.
