  • Alkaline preparations based on the mercaptocarboxylic acids show hair damage despite sufficient action, which manifests itself, for example, in increased hair breakage. In many cases, these agents also have an undesirable impact on the scalp.
  • thiolactic acid 2-mercapto-propionic acid
  • the mercaptocarboxylic acid esters which allow hair shaping even at lower pH values, are unsatisfactory in terms of their skin tolerance and their risk of sensitization.
