3 months post op, is this normal?

Transplanted hairs may take 6 to 12 months for growth.  If you are worried about the progress, you should follow up with your doctor.

At 3 months most patients do not see any growth of the transplanted hair.  The grafts will begin to grow at different rates between 5 to 6 months after transplantation.  The grafts go into a dormant phase for this period of time and then start to grow each at different rates.  You can expect to see results around 12 months after your procedure.

At 3 months I most patients don't have any growth, though some do. You have no cause for worry, as it usually takes closer to 6 months to start seeing growth. In some cases it may take 9-10 months and patients are still happy with the end result. Just be patient and try not to worry too much in the meantime.
