Hair taken from another person cannot be transplanted to another person, even if the patient is a sibling, mother, father or a different person with matching tissues. The reason for this is that each hair follicle is an organ on its own and each hair follicle can cause incompatibility independently. Even if the tissues seem numb, the possibility of rejection of the body continues to be insignificant even in the transplantation of large organs. 3000 organs are transplanted in 3000 graft hair transplantation. Therefore, the risk of tissue incompatibility is very high. When all these are evaluated together, hair transplantation is not performed between different individuals.
