Why microscopes are critical in hair transplants (photo)

Here is a photo of what appears to be a single hair for grafting, but because it can be viewed with a high powered microscope, we see that there is at least one if not two telogen hairs present (see arrow). If this graft was put in the frontal hairline, then it would look pluggy. Does your surgeon use a high powered microscope to make sure that the hair transplant is done correctly?
