Dr Cole,
It is natural for physicians to have diverging opinions. The history of our field is replete with this. Healthy debate has been a major stimulus for growth in mainstream medicine. I see no reason why this should not be the case amongst the physicians engaged in the procedure of hair restoration.
There appears to be an agreement on the fact that an increase in length may (not always) occur with body hair relocation. And I do not see a diverging opinion on the fact that caliber (a key contributor to volume and coverage) is typically unmoved.
There appears to be agreement that shock loss occurs from the injury that occurs during slit preparation rather than the actual placement of a graft. When a slit or a punch injury is inflicted to an area adjacent to a pre-existing hair, the trauma generates an inflammatory response that could result in shock loss. The chances are increased if the pre-existing hair is physically injured in the process. Also, larger injuries would result in relatively more inflammation. Larger punch injuries would result in more infalmmation relative to finer blade/needle tip stab injuries.
There appears to be agreement that body hair would grow in head donor areas. I have shown in the leading post 2 patients that have benefited from such a procedure.
However, we seem to have differing opinions on the best time for transplantation of the donor area of the scalp. I am of the opinion that in any hands, the larger wounds left in the wake of some FUE extraction sites would not optimally fit an often finer/often shorter body hair follicle (smaller diameter) to the extent that allows for imbibition, neovascularization, etc. to occur optimally. It is my opinion that the duration that elapses during a single clinic visit would not have been long enough to change the odds for the graft to optimally thrive. In other words, the degree of shrinkage and the organized blood clot or vacuous space into which the grafts would be placed does not present the perfect milieu for optimal graft take. Given the size mismatch and the location of the recipient (back and sides of the head) which is subject to disruptions at sleep/rest times, the chances of graft displacement including insetting with resulting pitting and encystations is not optimally controlled for. In all while some grafts would take, the chances would be optimized further by deferring the procedure all together to a different timeline.
I have read of FIT-farming for some time, but there appears to be a paucity of photo documentation of the procedure, including before, inta-operative and post-operative-result photos. I would be most appreciative if you could present some photographic evidence of several instances of this.
Regarding limits to session sizes; my positive experience with 9000+ BHT cases thus far does not support the 5000-6000 graft limit as the reason for poor yield that may have been cited for poor outcomes in some BHT megasessions. Several factors could account for poor yield.
As for studies, many variables go into determining the outcome of a study. I have found that a lot has to do with the design of a study and the interpretation that follows subsequently.
The principles for repigmentation of skin is another aspect of dermatology that I would hope to discuss some other time.
