Is it really 2500 grafts? (Photo)

That indeed looks like subpar work. You can measure it for yourself but the density looks about 10 per square cm. The grafts look like minigrafts instead of micrografts that are not commonly used in the last decade, which may cause a doll-like appereance especially if the angles were not created right. At this point you have to hope that they grow in an acceptable fashion and that your donor area was preserved for future sessions. After getting the result in about a year, you should do your homework and search for a skilled surgeon to proceed with.

Photographs can be very deceptive and yours only shows the from of your head. However it certainly doesn't look like a density of 45 per square cm. If there wasn't significant grafting in areas not shown by the photograph then it is also unlikely you had 2500 grafts.You might want to seek the advice of a lawyer.If the doctor is a member of the ISHRS - International Society of Hair Restoration Surgery - then you might also want to seek advice from this Association.It is difficult to predict what your appearance will be like once the transplanted hairs have grown but if you aren't happy then I'm sure a reputable hair transplant surgeon will be able to improve things. Of course, more experienced surgeons tend to be more expensive!
