Fibers for hair, method for producing same, fiber treatment agent and hair accessory

Abstract

A fiber for hair, having a base fiber, and a cationic surfactant and a nonionic surfactant which are present in at least a part of a surface of the base fiber, in which the cationic surfactant has a carbon chain having 18 to 22 carbon atoms, the nonionic surfactant has a carbon chain having 10 to 20 carbon atoms, an HLB value of the nonionic surfactant is 14.0 to 19.0, a content of the cationic surfactant is 3 to 20% by mass based on the total amount of the nonionic surfactant, and a total amount of the cationic surfactant and the nonionic surfactant is 0.002 to 4% by mass based on the total amount of the fiber for hair.
