You are just three months from your procedure, and usually around three months growth starts. Please be patient
As per your pictures, either you have experience quite a shock-loss or your existing Hair has disappeared. Frankly speaking you should have left your crown on medications. I don't know why Eugenix decided to transplant grafts on crown?
I will only advice you to wait for at least a year before deriving any conclusion, Dr. Das is a good surgeon, don't stress on second procedure right now, just focus on your recovery and please remember one thing, once you start Finasteride or Minoxidil you need to stay on it forever. Never stop those medicines if they are working for you.
