The present invention relates to a polyester-based fiber for artificial hair containing a polyester-based resin composition, wherein the polyester-based resin composition contains 5 to 40 parts by weight of a brominated epoxy-based flame retardant, 0.05 to 3 parts by weight of a polyester resin molecular weight modifier, and 0.2 to 3 parts by weight of a phosphite-based compound, with respect to 100 parts by weight of a polyester resin, and the polyester resin is one or more selected from the group consisting of polyalkylene terephthalate and a copolymerized polyester mainly containing polyalkylene terephthalate. The polyester-based fiber for artificial hair of the present invention can be produced by melt kneading a polyester resin composition, and melt spinning a polyester composition after the melt kneading into yarns. Also, the present invention relates to a hair ornament product containing the polyester-based fiber for artificial hair. The present invention can provide a polyester-based fiber for artificial hair having excellent flame retardance and further having gloss and tactile feel close to that of human hair, and a hair product containing the same.
