=== Pathway associated with anti-androgen ===
* Dihydrotestosterone
** Formed by peripheral conversion of testosterone by 5-alpha reductase
** Binds to androgen receptor on susceptible hair follicles
* Hormone-receptor complex activates genes responsible for gradual transformation of large terminal follicles to miniaturized (progressive diminution of hair shaft diameter and length in response to systemic androgens) follicles
