How long does it take for Microneedling to work?

Generally, it usually works within 6 months of starting it assuming that the hair loss started recently (past 2-4 years). I don’t have experience with DUPA after a hair transplant. I would guess it will not work as well as without a hair transplant, especially if the hair loss is recent.
