I noticed some of my new grafts transplanted 5 months ago still do not have hairs growing. I am under the impression when you transplant, the hairs reset to the telogen phase, but this phase is only 3 months. So to me I would assume that all FUE grafts would be having hairs growing out of them, and the ones not growing, even if it's just thin wispy hairs, are to be considered dead.
I do understand waiting 1 year before final determination, but I assume all my grafts should be having some type of growth by now, no matter how thin or vellous the hairs are. A good portion of my grafts do have growth fortunately.
