That conclusion that you cited was with regard to females developing baldness. And yes, i do believe there are other factors that can contribute to baldness, especially in women. Btw, it's not because people have PhDs they can't be wrong. I don't know about testosterone being converted inside the follicles, but it could be true. But even then, i don't see how that leads to testosterone levels or DHT levels inside mice being insignificant. How do you explain then why castrates never develop baldness? They still make very small amounts of testosterone. If the level of testosterone is insignificant they should also develop baldness.
