<p>The application relates to the use of a combination of active agents consisting of (A) alkoxylated lanolin alcohols and (B) a pyrrolidone carboxylic acid and/or a pyrrolidone carboxylic acid derivative of general formula (I) in which at least one of the constituents R1 to R3 stands for a -COOR4 group in which R4 is hydrogen, an alkaline metal ion, an alkaline earth metal ion or an ammonium ion +NHR5R6R7, in which R5 to R7 are mutually independently hydrogen, alkyl groups with 1 to 22 carbon atoms, hydroxyalkyl groups with 1 to 4 carbon atoms, alkenyl groups with 2 to 22 carbon atoms, acyl groups with 2 to 22 acyl atoms or possibly substituted aromatic groups with 6 to 10 carbon atoms, and the remaining constituents R1 to R3 are hydrogen or alkyl groups with 1 to 4 carbon atoms, in aqueous preparations for washing and the care of hair. It is thus possible to obtain a strong equalising effect with an amazingly high degree of hair care in the case of dyed hair.</p> |
