PURPOSE: A cosmetic composition containing vinyldimethicone/dimethicone copolymer and silicone and their use are provided, which has improved cosmetic characteristics in relation to easiness of unravelin, smoothness and pliability of the hair. CONSTITUTION: The cosmetic composition comprises a cosmetically acceptable medium, at least one silicone and an emulsion which comprises at least one silicone copolymer of viscosity 10¬6 to 100x10¬6 cP obtained by reacting (a) a polysiloxane of formula(I) and (b) at least one silicone compound with one or two groups reactive with the terminal groups(R1) of (a) the polysiloxane by using a catalyst. At least one of (a) and (b) contains ethylenically unsaturated aliphatic groups. In formula(I), R1 = H or ethylenically unsaturated group, particularly vinyl, allyl or hexenyl; R2 = 1-20C alkyl, 5-6C cycloalkyl, 7-20C aralkyl or OH optionally with ether, amino, carboxyl, hydroxyl, thiol, ester, sulfonate or sulfate groups; and n = number giving a viscosity of 1 to 1x10¬6 mm¬2/s.
