One prescription drug has been approved by theHair Revital X Review US Food and Drug Administration for the treatment of one type of alopecia. That type is male pattern baldness. The drug is called finasteride. Finasteride was originally used to treat benign prostatic hyperplasia or enlarged prostate. It works by inhibiting the production of an enzyme that converts free-testosterone into dihydrotestosterone or DHT.
DHT sensitivity is believed to be the primary cause of genetic androgenic alopecia or inherited pattern baldness in men. In women, the causes are believed to be more complicated and may include decreased estrogen production.
The pharmaceutical company responsible for finasteride reported that 48% of the men in a five year study experienced no further loss of hair and some regrowth after two years of taking the drug. But, use of the drug is accompanied by many unwanted side effects, including, in some cases, erectile dysfunction.
Since there is no way to determine, ahead of time what side effects a man might experience, hormonal experts suggest that other products for hair loss should be recommended first and that finasteride should only be used as a last resort.
