Hair Loss Drug Options - How It Works
The hormone DHT, or Dihydrotestosterone, is the cause of hair loss in genetically susceptible men. Finasteride acts as a DHT blocker, stopping the formation of Dihydrotestosterone almost immediately. The typical result is a decrease in the level of hair shedding and can be seen in as little as three months. Men who forgo this hair loss treatment will continue to experience hair loss.
