Not uncommonly a significant percentage of transplanted hair does not fall out but rather keeps growing. It's a good idea, though, to be prepared for the grafted hair to fall out because most hair usually does go into this resting period. It is important to realize that some of the immediately surrounding hair can also go into the resting phase. This period, then, beginning at three weeks and ending at three to four months when your transplanted hair starts to come out of the resting phase will have at least as thin an appearance as before your procedure. A little patience is required here!
