Hair transplantation is the surgical procedure which removes hair follicles from one part of the body, called the 'donor site'. Hair follicles are the sheath of cells and connective tissue which surrounds the root of a hair. This technique is used to treat male baldness. In this minimally invasive technique, grafts containing hair follicles that are genetically resistant to balding, are transplanted to the bald scalp. Hair transplantation technique can be used to restore eyelashes, beard hair, eyebrows, chest hair, pubic hair and to fill in scars caused by accidents or surgery such as face-lifts and previous hair transplant. Hair naturally grows in groupings of 1 to 4 hairs. Hair transplant surgeries harvest and transplant hair "follicular units" in their natural groupings. Modern hair treatments can achieve a natural appearance by mimicking original hair orientation. This kind of Hair Transplant Surgery is called follicular unit transplantation (FUT). There are two different way to harvest donor's hair such as strip harvesting, and follicular unit extraction (FUE).
