Most guys take it for their enlarged prostates as it helps shrink it back down through its ability to minimize DHT, this prostate shrinking leads to better pissing flow, Better Erections etc..
Its also used to treat male pattern baldness "androgenetic alopecia”
It works by decreasing the amount of a natural body hormone (DHT). Decreasing the amount of DHT leads to increased Hair regrowth and slower Hair loss and the DHT is no longer strangling your hair follicles down to nothing! lol .
Hair growth on other parts of the body is not affected by Finastra.
It takes a couple months to see the hair regrowth and become fuller again. However once you cease the finestra the DHT will build back up again if your stilling using hormones that convert to DHT.
