Hair transplantation is a surgical procedure in which hair follicles are removed from the "donor site" on one region of the body and placed on the "receiver site," a bald or balding area. Male pattern baldness is the main condition that this method is used to address.
Grafts with hair follicles from areas of the body that are genetically resistant to balding, such as the back of the head, are transferred to the bald scalp during this minimally invasive surgery. Hair transplantation can also be used to cover scars from accidents or surgery, such as facelifts and prior hair transplants, and to regrow hair on the chest, pubic area, beard, eyebrows, eyelashes, and eyebrows.
In contrast to skin grafting, hair transplantation uses several microscopic grafts rather than a single strip of skin and contains practically all of the epidermis and dermis around the hair follicle.
Current methods for harvesting and transplanting hair "follicular units" preserve the natural clusters of 1–4 hairs that hair grows in since this is how hair grows in nature. Thus, by imitating the original hair direction, contemporary hair transplantation can provide a natural-looking result. Follicular unit transplantation is the name of this hair transplant process (FUT). Strip harvesting and follicular unit extraction are two methods for obtaining donor hair (FUE).
