One of the most effective drugs against baldness is the drug finasteride, which prevents the conversion of testosterone to dihydrotestosterone. Initially it's a cure for baldness was focused on the prevention of prostatitis, because it reduces the inflammation of the prostate. In addition, the drug is considered to be one of the best means of prevention from prostate cancer.

It turned out that the most common disabilities are loss of libido, a decrease in the number of sperm, decreased libido, impotence and depression. And victims of this are up to 23% of men receiving finasteride, and half of the changes are irreversible.
