Before understanding the hair transplant we should understand the meaning of word TRANSPLANT. TRANSPLANT means moving a organ or tissue from one body to another or within body. You must be aware of organ transplant e.g. kidney , liver, heart transplant. Organ transplant works on the principle of reconnection of blood supply and nutritional supply from new body or new location where the tissue or organ is transplanted or fixed.
Though it sounds very easy but it requires great skills and great tissue handling when it is outside body or original location and most important its skilful placement/fixing/implantation at recipient site.
Even after such a great care the survival of organ or tissue/ transplant depends upon the reconnection of blood supply and nutritional supply to recipient site.
