You don't want to inhibit DHT. Bad idea. DHT helps control estrogen in men....this is why some men on DHT blocking drug Proscar get gyno.
DHT also plays a role in sexual functions.
If you are worried about Hair loss, use nizoral. For prostate protection, use pygeum and/or stinging nettle.

what is nizoral, and how do i get it?

i was on nizoral's website and it states in does not prevent Hair loss, but only dandruf?

Moved to the appropriate forum.......
