In a very recent question, asked about hair cloning, you mentioned that “theoretically you will have an endless supply of hair and your hair density can be as high or higher than what you started with”. In another entry of yours, Dr. Rassman, we read that “Hair can be transplanted at a density that approaches 35% of the original density in many people.” and that “the ability to place such densities depends upon many factors which include: hair thickness, skin characteristics, the size of the instruments for making sites, the skill of the surgical team at placing grafts tightly together and the processes that reflect the quality management of the surgical team.”
What is different about hair cloning different, which allows us to place the grafts so tightly together that you will end up with a density of _100%
Perhaps there is a misunderstanding that I would like to clear up.
There is no limitation on the density of transplanted hairs, except on a per session basis. How close you can put the grafts together during surgery depend on the width of the grafts (not hair). Some grafts can be 1/16 to 1/8 of an inch wide.
You must understand that hair transplant surgery involves moving hair from one location to another location. It does not create new hair. Let’s say that you got 35% of your original density in one session, then you want the same number of grafts transplanted again, assuming that the donor supply is as good, you can probably come close to doubling the 35%. Again, if you then wanted to do another 35% equivalent grafts, you will be getting close to 100% of the original density. There is actually some limits to this process, for example, what is the size of the donor area, the blood supply and the availability of grafts from the donor area. When grafts are placed very, very close together, we call this term “dense packing”, a term I defined in 1994 in the Hair Transplant Forum.
If you are a completely bald Norwood 6 patient and want your original density of 200 hairs in a square centimeter, where would the donor hairs come from? You only have a limited number of donor hair and the surgeon has to use judgement to create the most effective use with limited number of donor hairs you have. Unless there is cloning, putting in an unlimited number of hairs is impossible.
If you are a Norwood 3 and want the original donor hair density, then it may be possible with multiple surgeries.
