Alopecia Areata is a condition when hairs are lost in a short period of time. Alopecia affects both men and women with equal frequency, but the condition is mostly prevalent among adolescents and children. Initially, small oval or round bald patches are noticed with not much of symptoms. Though there might be little pain or itch in the affected area. It may occur anywhere where the hair is present, but the most common sites are beard and scalp.
Follicular Unit Grafting or FUT is one of the modern techniques of hair transplantation used for alopecia treatment. The natural hair grouping of two, three or four hairs in a close bunch is a follicular unit. Also, a small number of single hairs can be grown on their own. These natural groupings are kept together by hair transplant surgeons and surgically moved generally using two major techniques.
In the first method, a strip of hair bearing scalp from the back of the head is removed and then stitched. The hairs above the site of surgery cover the staples or stitches until they heal and leave a scar, which widths around 1mm. Then the strip of hair and skin is cut apart under microscopes for isolating the follicular units.
Follicular Unit Extraction or FUE is the other hair transplant method that can be used to treat alopecia. In this method, each grouping is carefully cored out with a tiny punch. Generally, the back portion of head needs to be shaved in this process and small dot scars can be seen when the scalp heals. During the process, a small incision is made in the bald area to insert the follicular graft units. Normally, in each square centimeter of bald area, twenty to forty follicular unit grafts are placed after applying local anesthesia on the patient.
