I had a transplant on the hairline a few years ago while on finasteride, I have thick har everywhere except on the hairline where I did the transplant and I was thrilled with the results.
Two years after the surgery, my finasteride ran out and being in a different country, I got a different prescription(brand), a few months after that, my transplanted hair fell of(only transplanted hair), regrew and fell off constantly for two years, being very distressful for me.
After having no clue what it was I suspected maybe the finasteride I've been taken wasn't legit, I got sent the original finasteride from the farmacy that I took years ago.
Within a week I felt sensation on the breast area which tells me there is estrogen levels rising which I didn't feel for the 2 years taking the other pills, and now at 4 weeks after I am experiencing again an overnight shed of transplanted hairs!
Could this be possible if I had been taking expired or placebo fin and now that I got the legit one?
