Spiky short hair that does not grow after 8 months of combined FUT/FUE transplant. Is there chance for growth? (photo)

8 months ago, I had a combined FUT/FUE surgery (2500 grafts to frontal, mid, and vertex scalp). There are about 100 hairs near the crown area that do not grow (length 2-3mm) and they have been there at the same size for the past 4 months (Perhaps some of them from day one). They are sturdy and do NOT easily come out. Is there any chance that they still grow? My doctor has lately been missing in action due to an illness so I would appreciate any input that you might have.
