Abstract
An artificial hair which is composed of synthetic fibers such as acrylic fibers or vinyl chloride fibers and which is characterized in that the cross section of each fiber has a shape consisting of one major axis and at least two minor axes nearly perpendicular to the major axis and that the single-fiber fineness is 25 to 70 dtex. This artificial hair is soft to the touch and bulky (voluminous) to impart a good feel to hair accessories and exhibits excellent combing properties and braidability, thus giving hair accessories (such as wigs, hairpieces, braids, extension hair and doll hair) which have excellent feel and settability.
