Will Propecia Make My Beard Not Develop?

I have read on various web-sites that beard growth is stimulated by DHT. I am 20 years old and have yet to develop a full beard. I take propecia for male pattern baldness, is this likely to have a noticeable effect on the development of my facial hair or stop it completely?

Probably not, but the human physiology is not so simple. Beard development (or non-development) is not a typical side effect of Propecia (finasteride). If you don’t grow a beard for some reason, the most likely culprit is your genetic trait and not the drug.
