<Tr> <Td_colspan="2"> A graft transplantation to cover the scar of a Hidradenitis suppurativa operation on the back of the head </Td> </Tr> <Tr> <Td_colspan="2"> (edit on Wikidata) </Td> </Tr> <P> Hair transplantation is a surgical technique that removes hair follicles from one part of the body, called the' donor site', to a bald or balding part of the body known as the' recipient site' . The technique is primarily used to treat male pattern baldness . In this minimally invasive procedure, grafts containing hair follicles that are genetically resistant to balding, (like the back of the head) are transplanted to the bald scalp . Hair transplantation can also be used to restore eyelashes, eyebrows, beard hair, chest hair, pubic hair and to fill in scars caused by accidents or surgery such as face - lifts and previous hair transplants . Hair transplantation differs from skin grafting in that grafts contain almost all of the epidermis and dermis surrounding the hair follicle, and many tiny grafts are transplanted rather than a single strip of skin . </P> <P> Since hair naturally grows in groupings of 1 to 4 hairs, current techniques harvest and transplant hair "follicular units" in their natural groupings . Thus modern hair transplantation can achieve a natural appearance by mimicking original hair orientation . This hair transplant procedure is called follicular unit transplantation (FUT). Donor hair can be harvested in two different ways: strip harvesting, and follicular unit extraction (FUE). </P>
