How it works

PROPECIA works on a key cause of hair loss by significantly reducing the amount of DHT. Specifically, PROPECIA inhibits the formation of DHT in your scalp. Lowering DHT appears to inhibit the further shrinking of affected hair follicles. DHT is a substance in the body that can shrink the hair follicle until it no longer produces visible hair. Scientists believe DHT and family history are key factors in hair loss. PROPECIA helps regrow visible hair and reduces further hair loss.( Figure 1 )

Although results will vary, generally you will not be able to grow back all the hair you have lost.

If you start taking PROPECIA you may see a decrease in hair loss beginning in as little as 3 months. And by 6 to 12 months, you may see new hair growth. If PROPECIA doesn’t work for you after 12 months, it is unlikely to be of benefit. If you stop taking PROPECIA, you will likely lose any hair you’ve gained within 12 months of stopping treatment. PROPECIA has been used by more than 1 million men in the United States since the drug’s introduction in 1998.

PROPECIA can affect a blood test called PSA (prostate-specific antigen) for the screening of prostate cancer. If you have a PSA test done, tell your doctor that you are taking PROPECIA.

When you could see results

Take PROPECIA daily and you could see results in as little as 3 months. If you stop taking PROPECIA, however, your results will gradually go away over 12 months. And if PROPECIA hasn’t worked in 12 months, further treatment is unlikely to be of benefit.
