Definitions

  • the present invention relates to hair treatment compositions containing Bunte salts of amino acids and specific oligopeptides or peptides. These hair treatment compositions are particularly suitable for gentle bleaching or whitening hair dyeing.

  • a third object of the present invention is a process for the oxidative dyeing and / or whitening of hair, in which the preparations of the kit - either sequentially or as a mixture - applied to the keratin fibers and the hair is washed.
  • the lightening is also accompanied by damage to the hair, as not only the dyes of the hair, but also the other structural components of the hair are oxidatively damaged. Depending on the severity of the degree of damage, this ranges from rough, brittle and difficult to comb hair over a reduced resistance and tear resistance of the hair to hair breakage.
  • oxidative hair damage is constantly looking for new ingredients and active ingredients.
  • Corresponding active ingredients can be used both as pretreatment agent before the oxidative dyeing or whitening process, during the oxidative treatment - as an additive to the oxidative dyeing or bleaching agents - or as a post-treatment agent.
