Hair transplantation is a surgical technique that moves individual hair follicles from a part of the body called the ‘donor site’ to bald or balding part of the body known as the ‘recipient site’. It is primarily used to treat male pattern baldness. In this minimally invasive procedure, grafts containing hair follicles that are genetically resistant to balding are transplanted to the bald scalp. It 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.
Since hair naturally grows in groupings of 1 to 4 hairs, today’s most advanced techniques harvest and transplant these naturally occurring 1–4 hair “follicular units” in their natural groupings. Thus modern hair transplantation can achieve a natural appearance by mimicking nature hair for hair. This hair transplant procedure is called Follicular Unit Transplantation (FUT). Donor hair can be harvested two different ways.
