The present invention relates to the heat treatment apparatus which applies heat energy to chemical applied hair for hair treatment procedures such as perming or dyeing and the hair styling procedures using such apparatus. It involves transferring the heat energy to chemical applied hair by transferring heat to the metal member of heat transfer coefficient of 150 kcal/m2H° C. or more from the electric heater and then, transferring heat to the non-metal member with heat transfer coefficient of 0.20 kcal/m2H° C. or less. The procedure is characterized by the heat transfer by the contact between the non-metal member and chemical applied hair. Also, it provides various hair styling methods where a high temperature heat is applied to the hair, making the main ingredient of the hair, keratin, react to the heat and relax while the hair expands, allowing more active penetration and escaping of the dye.
