I think when they make these hasty announcements about potential cures, what they’re failing to take into consideration is that the thing they’ve discovered may be “necessary but not sufficient” to regenerate terminal hairs.
They’re implying that restoring the Tregs cells alone could regererate hair. We’ve already heard that kind of story before… “Blocking PGD2 will regenerate hair”… “Stimulating the wnt pathway will regenerate hair”… “Adding PGE2 will regenerate hair”… “Adding this one protein will regenerate hair”…
The problem is that DHT, interacting with genetically sensitive follicles, causes a cascade effect that completely screws up the metabolism of the entire follicle and all its cell types.
Just restoring a single element of all this back to its original conditions isn’t going to solve the problem. You have to restore ALL of the elements together.
That’s why, to my mind, the real answer lies in the research that seeks to build brand new follicles from the ground up.
