Rogaine doesn't work by inhibiting dht. It works as a vasodialator, meaning that it allows for more blood flow to your follicles. It helps give back some zip to ailing follicles. It doesn't address the root cause though (high androgens or dht)

In fact, one of the side effects of rogaine is increased facial hair, even if not used on the face (some of it gets absorbed systemically)

For some that side effect is a deal breaker, for others it's just a small price to pay for the chance at slowing the loss and regaining some hair.

So I'd also look for either a topical or internal either androgen inhibitor/dht blocker or both to add aide in Rogaine's effectiveness.
