You're still missing the point of that reversing these things is not going to resurrect organs from the dead. Please explain to me how that would be scientifically possible by restoring collagen? Even in these articles you share, it says:
"Once stem cells go, there’s no getting them back, said Elaine Fuchs, a professor of cell biology and development at the Rockefeller University in New York, who was not involved with the study.
“Once the hair growth cycle goes, it goes,” she said. “Once hair loss is triggered, it’s a self-propelling event.”
Also, hairloss that is a result of senescence is not the same as male pattern baldness.
Lastly, male pattern baldness is not observed in Eunuchs, those bahamian men studied for finasteride, generally not observed in MTF transexuals (who often get substantial regrowth as well) and is statistically not common in women and over 200 genes that play into baldness were recently discovered as you may recall.
You're asking people to deny reality and facts about the condition to feed into the almost certainly false hope that restoration of old tissue will also reverse baldness. You don't have to be a biologist to realize that the two are not the same.
Whether you guys want to believe it or not, the evidence has mounted up that Androgenetic Alopecia is ultimately a complex, but hereditary trait that requires both male sex hormones and genetic disposition.
