Abstract: The present invention relates to a composition comprising a polymer, wherein this polymer is water-soluble and has a melting point of at least 145° C. and comprises sulfonic acid groups, and an organic amine having at least two amino groups, and optionally further cosmetic ingredients. Furthermore, the present invention relates to a process for restyling human hair comprising applying to the human hair a composition comprising a polymer, wherein this polymer is water-soluble and has a melting point of at least 145° C. and comprises sulfonic acid groups, and an organic amine, and optionally further cosmetic ingredients, thereafter heat-treating the hair, together with the composition on its surface, thereafter allowing the hair to cool down to a temperature of below 100° C., and thereafter changing the hair style by heat-treating the hair. Furthermore, the present invention relates to the use of the said polymer or of the said composition for restyling human hair.
