I used to have a thick, full brown beard.
A few months after I started taking Finasteride (1mg daily), I began noticing patches in my beard, and eventually even gray hairs started to appear.
Could this be caused by the DHT blocker?
I’m 23 years old, and within just six months, my beard on the chin has almost completely turned gray.
I honestly don’t know what to do anymore.
