I had 4 DHI hair transplants from 2021 -2025. The last one was on August 15th. Why isn’t my hair thickening? I’ve tried all kinds of pills, including finsteride minoxodil, and why isn’t anything working

You’ve had a bunch of transplants, which can take a while to show results fully, think 6-12 months at least. Keep using fin and min, consider checking for scalp issues that might affect growth, like sebderm. The recent transplant might still show results in due time.
