Abstract

Hair transplantation may be a surgical technique that removes hair follicles from one a part of the body, called the 'donor site', to a bald or balding a part of the body referred to as the 'recipient site'. The technique is primarily wont to treat male pattern baldness. During this minimally invasive procedure, grafts containing hair follicles that are genetically immune to balding (like the rear of the head) are transplanted to the bald scalp. Hair transplantation also can be wont to restore eyelashes, eyebrows, beard hair, chest hair, and bush and to fill in scars caused by accidents or surgery like face-lifts and former hair transplants. Hair transplantation differs from skin grafting therein grafts contain most of the epidermis and dermis surrounding the follicle, and lots of tiny grafts are transplanted instead of one strip of skin.

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 are able to do a natural appearance by mimicking original hair orientation. This hair transplant procedure is named follicular unit transplantation (FUT). Donor hair are often harvested in two different ways: strip harvesting, and follicular unit extraction (FUE).
