Pharmaceutical or cosmetic agents for use in hair treatment contain a betaine of formula (I): [Image] R1> - R3>H, Me or an optionally unsaturated, optionally cyclic 2-8C hydrocarbon; R4> - R9>H, -OR1>0>, -COR1>1>, Me (optionally with a 1H-imidazole-4 substituent) or an optionally unsaturated, optionally cyclic 2-8C hydrocarbon; R1>0>H, Me or an optionally unsaturated, optionally cyclic 2-30C hydrocarbon; R1>1>Me or an optionally unsaturated, optionally cyclic 2-30C hydrocarbon; x, y and z : integer 0-12, with at least one being other than 0; and Y : COO->, (SO3)-> or OH-> combined with a physiologically-compatible anion. |
