I had 2200 grafts FUE transplants done exactly 3 months ago. I have taken good care of my hair, however, something that I have noticed is that some of my transplanted hair are still the same size as when they were transplanted as seen on the image in red circles. When i touch my head I can feel sharp tiny hairs and its these hairs that have not shed or grown for the past 3 months. Do I need to be worried?
