Transplanting Grafts Into 1 Square Centimeter

can you fit 100 grafts in a 1sq2 cm without damaging existing hair ?

Yes, the density or 100 grafts per square cm can be achieved in some people. Generally it would take fine hair and supple skin with good elasticity to do it. The issue of a successful transplant is a more important issue. By crowding the grafts at 100 per square cm, the blood supply may be compromised. Some very crude studies of this have been done and presented at the past few ISHRS meetings (the largest society in the industry), which have shown that as more than 40 grafts are put into a square cm, the successful growth of these grafts starts to fall off significantly. If there is hair already present in the transplanted recipient area, there is great likelihood that it would damage the existing hair as well as obtaining poor growth.

I have seen this issue become one where doctor’s ego is pushed at the expense of patient welfare. Just because a doctor says he can do this, does not mean that this type of density has value and will grow out. I did the first dense-packing ever reported at about 100 grafts per square cm in 1993, but the growth was less than that number, so I toned down these numbers and developed judgments that allowed me to know just how far I could push densities at the time of transplants. Everything is strategy and judgments in the field of surgey. So I smile when I hear doctors talk about the high densities that they can achieve, realizing that they may be less patient outcome focused, and more in love with their own image in the morning mirror.
