Hair follicles of one’s siblings, mother, father, or someone with matching tissues cannot be transplanted on the patient. There is an important reason behind this. Hair follicles are organs on their own, and transplantation might lead to incompatibility. Even in the transplantation of larger organs or in the transplantation of one single organ, the body might refuse the transplanted organ even if the tissue compatibility is well researched.
In a hair transplantation of 3.000 grafts, 3.000 individual organs will be transplanted, and therefore the incompatibility of tissues is very high. Therefore, hair follicle transplantation between people, is not performed.
