I respect your opinion but Im just sharing what happened to me. I understand what the science says and I believe these medications work for the vast majority. I also believe that everyone reacts slightly differently but in some cases there is an adverse reaction. You’re right that I’m guessing at the reason for this. RH or upregulation. An immune response to the hormonal change. Whatever it is. I really don’t know or care. All I know is that I had some temple recession and 4 months into finasteride my mid scalp, forelock and crown all lost an incredible amount of density which never recovered but also never got much worse in 17 months.
If you want to say that was inevitable, a case of sudden highly aggressive hair loss which started and stopped abruptly that’s fine and I’m not going to argue your opinion. But a week after starting dutasteride after being on finasteride for 17 months my donor zone was shredded. And the mid scalp and crown which had maintained after the initial hit has also thinned out. You can go look at my pictures. There’s zero chance this is coincidental in my opinion. And I’m far from the only person reporting this type of reaction. At the end of the day it doesn’t matter what actually happened. It’s not going to get my hair back.
