Compositions and methods for the use of inhibitory nucleic acids, for exampl e small inhibitory ribonucleic acids (siRNA), to adjust, manipulate, prevent, inhibit, interfere, or block the androgen signal transduction pathway in a host cell, for example in a host's hair cell are provided. Aspects of the disclosure provide compositions and methods for interfering with the androge n signal transduction pathway by down regulating the expression of proteins involved in the androgen signal transduction pathway. Exemplary gene targets encoding proteins involved in the androgen signal transduction pathway inclu de but are not limited to isozymes I and II of 5-.alpha. reductase, the androge n receptor, aromatase, 3-.alpha.-hydroxysteroiddehydrogenase, 3-.beta.- hydroxysteroiddehydrogenase , 3-.beta.-hydroxysteroiddehydrogenase-~4-5- isomerase, 17-.beta.-hydroxysteroidoxidoreductase, and steroid sulfatase. In some aspects, the inhibitory nucleic acids, for example siRNAs, interfere wi th the expression of targeted genes by preventing, reducing, or inhibiting the translation of mRNA transcribed from the targeted gene.
