PROBLEM TO BE SOLVED: To provide a hair treatment agent in which porous silica doped with copper, which is excellent in deodorizing effect and texture after perm treatment, is blended so as to be stably dispersed and maintained. The hair treatment agent of the present invention contains a copper-doped porous silica surface-modified with a polymer containing a vinylpyrrolidone unit. Specific examples of the polymer containing the vinylpyrrolidone unit include a copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate, polyvinylpyrrolidone, and the like.
