I have just started taking Propecia on Tuesday (5/11/10) and almost instantly my beard has been growing slowly. Usually I shave on Monday mornings and Wednesday morningsâ€¦ Instead I have the amount of stubble on my face that would amount to 2 days of growth except it has been nearly 4 days..
What you’re describing is highly improbable after taking Propecia for just a day or two. While there’s been no identified link, some people do report slower facial hair growth after taking Propecia in very rare cases, but this would take weeks or months. And even then, I haven’t seen any proof that this occurs.
Look on the bright side, if Propecia does indeed slow your beard hair growth you will save 50% on your shaving supply and needs!
