Being Proactive with Propecia — Should I Take a Smaller Dosage?

I just received a prescription to start taking Propecia. I am still very young, 21, and have only mild hair loss. This is more of a proactive attempt to make sure things do not get any worse. My question to you is at my age, and with only mild hair loss, does it make sense to maybe take a smaller dosage each day? Maybe taking .5mg instead of 1mg. I have been reading many opinions online but would love to know yours. Thanks for your time.

Assuming you really do have genetic hair loss (without a good solid diagnosis, you really do not know), why would you take less than a fully effective dose that is proven to be effective? It makes little sense to me. Some people do suggest taking lesser dosages and even on this blog I have referenced such information. You are in command of your own destiny and that is what separates the men from the boys.
