View Full Version : Hair Transplant Yield

I'm sure I have beaten this question to a pulp, so, please bear with me! But I wanted to ask this question in one more fashion.

Let's assume a patient is going to have a strip hair transplant procedure. Let's say in one region of his scalp, he gets 20 grafts per square cm. In another region of his scalp, he gets 50 or more grafts per square cm. Would it be suspected that the yield (graft survival) is equal in both regions, say 95% or higher?

In my experience if performed properly, a yield of 95% or greater should be obtained if the transplanted follicular units are placed at 20 FU'S per sq cm or at 50 FU's per sq cm. There is an ongoing debate as to whether or not the yield starts to decline if even greater number of grafts are used. Some recent studies have shown equal success even when graft placement approached 100 FU's per sq cm. Remember everyone has a limited amount of donor hair. It should be used very wisely.
