An artificial hair and a wig using the same are provided which have the property of thermal deformation expanding upon heating by a hair drier or others used for hair styling. The artificial hairis made by mixing at the pre-determined ratio a semi-aromatic polyamide having a glass transition temperature between 60-120&#xb0; C. and a resin not expanding in said temperature range. The artificial hair may have a sheath/core structure comprising a core portionB and a sheath portion covering the core portion. As the resin not expanding in said temperature range, polyethylene terephthalate or others can be used, and as the sheath, nylon 6 or nylon 66 can be used. Said artificial haircan maintain its shape at room temperature or after shampooing due to thermal deformation by heating in steam atmosphere at temperature of glass transition or higher or about 80-100&#xb0; C.
