Like it or not, people with moderate to aggressive MPB are simply not going to maintain without some sort of anti-androgen or 5ARI, whether it's topical or systemical.

That's why it's so ridiculously funny that you come here and act like we are "miles behind on hair loss knowledge" and you somehow have good understanding of baldness.
