On the evidence of forummers here (scientific, it isn't, I know) it seems most people who obtain great results is due to minoxidil alone. Minoxidil seems to make the existing hair thicker and grow new hairs. It seems to me a lot of people have either damaged their results by adding peopecia or topicals that are said to have similar effect i.e. revivogen. A lot of people also claim to gain benefits by adding nizarol because it reduces or stops irritation. If minoxidil is the cause of hair regeneration, it poses the question of whether DHT is, in fact, the real cause of hair minituarization?
