Propecia Finasteride 4
Alopecia is the destruction of the hair follicle, which occurs due to the impact of biologically active forms of male sex hormone dihydrotestosterone. Propecia has a mild effect on the body: finasteride inhibits the reaction of hormone synthesis, blocking its action. Gradually there is a slowdown in the process of hair loss. Perhaps a complete restoration of the hair bulb.

Propecia has one indication for use - is the prevention and treatment of hair loss by male type. The defeat of the hair follicles is due to the activity of dihydrotestosterone, which is a biologically active form of male sex hormone. Finasteride-the active component of the drug, is able to suppress the biological synthesis of this substance, as well as partially block its effects.
