It is more common within the male population to treat male pattern baldness, although women undergo it too. Usual terms are: FUE - folicular unit extraction, FUT - folicular unit transplantation ili DHI - direct hair implantation.
Hair transplantation is performed in a way that moves hair follicles from a part of the body called the 'donor site' to a bald or balding part of the body known as the 'recipient site'. 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.
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).
This procedure is performed in local anesthesia. Up to 2500 hairs can be transplanted in one day, sometimes even more, depending on the graft score. Patient can communicate with the surgeon at all times and relax completely during the entire procedure. Depending on the quality of the donor’s area, several thousand hairs could be harvested. The quality of te donor’s area is measured by the graft score, which is ratio of number of hairs and number of harvested spots. The higher the score, the better quality of the donor’s place is. According to the latest recommendation from Edinburgh in 2014, hair transplant can be repeated safely in the same region after 14 months.
