1. A cosmetic composition for hair care comprising at least one water-dispersible cationic surfactant in proportions of from 0.05 to 7% by weight, at least one polypeptide carrying quaternary ammonium groups at the end of the chain or grafted on the chain in proportions of from 0.05 to 7% by weight, and at least one cationic silicone polymer in proportions from 0.05 to 7% by weight of the total weight of the composition, said one cationic silicone polymer being a product of the general formula:
