PROBLEM TO BE SOLVED: To obtain a silicone elastomer that can exhibit it usefulness in the treatment of human hair, skin and armpits by allowing a≡SiH-containing siloxane to crosslink with an unsaturated hydrocarbon silicon in the presence of low-molecular-weight siloxane fluid. SOLUTION: In the presence of a platinum catalyst, (A) a≡Si-H-containing siloxane is allowed to react with (B) a monoalkenyl polyether until a polyether group-bearing≡Si-H-containing siloxane is formed. Then, (C) the polyether group-bearing≡Si-H-containing siloxane and (D) an unsaturated hydrocarbon, for example,α,ω-diene are allowed to react with each other (E) in the presence of a platinum catalyst in a solvent until a silicone elastomer is produced by adding≡Si-H to the double bonds of theα,ω-diene by crossing. The molar ratio of the polyether to≡SiH group in the≡SiH siloxane is preferably 0-1.
