Dr. Paco Jimenez identified the eccrine gland in the upper part of the hair follicle. We discussed that when the surgeon creates chubby grafts in a hair transplant, the eccrine gland is included in the grafts, but when the grafts are very skinny, or stripped of their capsule as with some FUE grafts, this gland probably is not included in the graft. We have seen that chubby grafts produce the best long-term results, and skinny grafts may possibly be responsible for grafts that don’t continue to grow through many growth cycles. This is all speculation at this time, but Dr. Jimenez believes that he will hone down further on the value of the eccrine gland in the near future.
I have always believed that chubby grafts are better than skinny grafts and my results of seeing long-term growth has been very good. I also believe that chubby grafts reduce the risk of dehydration of the grafts during the hair transplant process. Dehydration of the grafts is the major cause of graft loss during a hair transplant surgery.
