Alopecia areata or shock loss after FUE transplant? (Photo)

I have had back in 2014 my first hair transplant. As the hair loss progressed, a second surgery was done 3 month ago. Whilst everything went well, I started to develop a bald patch within the donor area which got bigger over the last 3 weeks. I have contacted the clinic in question which advised me to take a combo of retin-A, 5% minoxidil and a topical steroid cream. The first 4 pictures were taken today. The fifth picture was taken in January (7 weeks after the transplant)
