people who reduce it regrow hair,

Yes, but they take finasteride, which is likely progesteronic by itself. I don't think it is that simple. Scientists have though for years that benign prostatic hyperplasia was due to DHT as well, because people that lack DHT naturally, don't suffer from BPH. However, the latest research seems to suggest the opposite, that DHT is protective for BPH.

Progesterone is feminizing, so basically you say, the only way to keep your head full of hairs is to become feminized. Lots of people with very high T and DHT level, have a full head of hair. Actually, when T and DHT begin to decline, with aging, hair loss becomes much more common.
