Follicular Unit Extraction Explained — Often abbreviated FUE, this procedure is a method of hair transplant in which follicles are extracted from one location and implanted in an area affected by hair loss. The location in which hairs are extracted is commonly referred to as the donor area. The area in which hairs are implanted is known as the recipient area.
Typical procedures using basic FUE tools are limited to the back of the head for donor grafts. This area on the middle back of the head is known as the safe donor area (SDA). Typically, it contains about 5,000 – 7,000 grafts.
