The present invention relates to a composition for washing and conditioning keratin fibers, comprising, in a cosmetically acceptable medium: at least one washing base comprising at least one anionic surfactant, and at least one anionic or nonionic amphiphilic diblock copolymer, comprising a hydrophilic block and a hydrophobic block, other than a diblock copolymer of ethylene oxide and of propylene oxide, a urethane block copolymer and a siloxane block copolymer, where the amphiphilic diblock copolymer has a ratio of the number of monomer units in the hydrophilic block to the number of monomer units in the hydrophobic block ranging from 7 to 24. The invention also relates to the method of using this composition for washing and conditioning keratin fibers, such as hair, and to a process for washing and conditioning keratin fibers using it.
