Yeah, I see some threads about it. There might be different reasons for it, but if you want to play it safe you can start with Progest-E instead.I say that because I see people here reporting worse hair loss after taking niacinamide or pregnenelone (even though theoretically preg should have no negative effects?)
That's a very fair point, which I pondered for a long time. But I think it goes with the implicit assumption that regrowing hair would be everyday business, at least to some extent. And in the human history, person would rather go in just one direction, downhill, healthwise. Everything else, if had happened, was treated as a miracle. It's not trivial to repair yourself and you can see it even on this forum, where, although with access to Peat's unprecedented knowledge and approach, people still frequently struggle.I don't know how reversible it really is. I feel like if it was that reversible we'd have more success stories. It seems like most success has been from people who managed to slow or stop the loss, and regained a point or two on the scale. That said it's clearly representative of an underlying problem, and fixing that problem should fix the hair-if it isn't past a state of no return.
If you want some context on how it could work biologically, to reassure yourself a bit, although it's not directly related to hair specifically, you can check Robert Becker's book The Body Electric (which I think is even uploaded somewhere on this forum), which deals with some phenomena, that would normally goes over science and daily experiences' head, in very serious and thorough manner.
