If your transplanted hair were extracted from non-safe zone then yes, they can potentially miniaturise as well. Finasteride is recommended not to prevent Hair Transplant from miniaturising, but rather to keep as many native hairs as possible. HT Is just an illusion of density, thus you need to have as many of your native hair as possible to get the overall decent look.I mean, won't your transplanted hair suffer if you stop?
Have you looked for another doctor in Portugal?
Thanks for the attention
I didn't hear of any other good Portuguese doctor to be honest.
