Claim:
A method of conditioning hair, said method comprising a step of applying an organopolysiloxane hair treatment composition to said hair; wherein said organopolysiloxane hair treatment composition comprises: an organopolysiloxane represented by the following formula (1), dispersed or dissolved in an organic solvent, R 1 a R 2 b R 3 c SiO (4-a-b-c)/2 (1) wherein R 1 is an organic group selected from the group consisting of alkyl groups having 1 to 30 carbon atoms, alicyclic groups, aryl groups, aralkyl groups, fluorinated alkyl groups and an organic group represented by following formula (2), —C d H 2d —O—(C 2 H 4 O) e (C 3 H 6 O) f R 4 (2) wherein R 4 is an alkyl group having 1 to 30 carbon atoms, provided that, when d=e=f=0, said alkyl group has 7 to 30 carbon atoms, or an organic group represented by the formula, R 5 —(CO)—, wherein R 5 is an alkyl group having 1 to 30 carbon atoms, R 2 is a group having at least one hydroxyl group or alkoxy group having 1 to 6 carbon atoms, wherein said hydroxyl group or alkoxy group is bonded to a silicon atom in the formula (1) directly or via an alkylenesilyl group, R 3 is a silicone compound residue represented by the following formula (3), wherein R 6 is a group selected from the group consisting of alkyl groups having 1 to 30 carbon atoms, alicyclic groups, aryl groups, aralkyl groups, and fluorinated alkyl groups, wherein when two or more of the groups R 1 , R 2 , R 3 , R 4 , R 5 or R 6 , respectively, are present in a molecule, such are the same with or different from each other, a, b and c each is a number with 1.0≦a≦2.5, 0.001≦b≦1.5, and 0.001≦c≦1.5, d, e and f each is an integer with 0≦d≦15, 0≦e≦50, and 0≦f≦50, x is an integer with 1≦x≦5, and y is an integer with 0≦y≦500.
