The invention relates to a method for the identification and/or production of an inhibitor of hair production. Moreover, the invention relates to a method for the inhibition of hair production. The invention also relates to a method for the production of a pharmaceutical composition. Furthermore, the invention relates to a pharmaceutical composition comprising an inhibitor of hair production identified or obtained according to one of the methods of the invention or a polynucleotide coding for the inhibitor, optionally in a pharmaceutically acceptable form of administration. The invention also relates to a pharmaceutical composition which comprises a polypeptide comprising the DNA-binding domain but not the transactivator domain of Whn, LEF-1 or Hoxc13, or a polynucleotide coding for said polypeptide, optionally in a pharmaceutically acceptable form of administration. Moreover, the invention relates to the use of a polypeptide comprising the DNA-binding domain but not the transactivator domain of Whn, LEF-1 or Hoxc13, or a polynucleotide coding for said polypeptide, of an inhibitor identified or obtained according to one of the methods of the invention or of a polynucleotide coding for such an inhibitor for the production of a pharmaceutical composition for the treatment of hair growth disorders. Not least, the invention relates to a kit for carrying out the methods of the invention.
