Will Propecia re-grow my hair?
Propecia works mainly to slow down or stop the progression of loss. It works mostly in the crown. Propecia is a DHT blocker meaning it helps stop the DHT from getting to the hair follicle and eventually killing it. Once a hair follicle has died at the hands of DHT, it is gone forever. Many men taking Propecia get disappointed when it doesn’t magically re-grow all their hair. Then, they stop taking Propecia and they then lose the hair that the Propecia was helping hold on to.
