Abstract: A polyvinyl chloride-based fiber for artificial hair that has excellent low glossiness and grip performance when woven and can be stably spun. Configuring a fiber for artificial hair using a polyvinyl chloride-based resin composition, wherein the polyvinyl chloride-based resin includes, at predetermined blending amounts, a polyvinyl chloride-based resin (A) having a viscosity-average polymerization degree of 450-1,700 and a crosslinked vinyl chloride-based resin (B) in which the viscosity-average polymerization degree of a component that dissolves in tetrahydrofuran is 1,800-2,300, the difference between the viscosity-average polymerization degree of the polyvinyl chloride-based resin (A) and the viscosity-average polymerization degree of the THF-soluble component of the crosslinked vinyl chloride-based resin (B) is in a predetermined range, and the cross-sectional shape of the fiber for artificial hair has a first projection, a second projection, and a third projection and the lengths and widths thereof satisfy predetermined conditions.
