摘要

Pharmaceutical or cosmetic agents for use in hair treatment contain a betaine. Pharmaceutical or cosmetic agents for use in hair treatment contain a betaine of formula (I): R<1> - R<3> = H, Me or an optionally unsaturated, optionally cyclic 2-8C hydrocarbon; R<4> - R<9> = H, -OR<10>, -COR<11>, Me (optionally with a 1H-imidazole-4 substituent) or an optionally unsaturated, optionally cyclic 2-8C hydrocarbon; R<10> = H, Me or an optionally unsaturated, optionally cyclic 2-30C hydrocarbon; R<11> = 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
