Hair transplantation field has gone through several changes in past few years. Various Hair transplant clinics and centers have been using a number of methods but FUT and FUE are most widely used hair transplant techniques that include transferring individual follicular units in their genetic form. Follicular Unit Transplantation is considered as traditional hair transplant methods that has now replaced by Follicular Unit Extraction. The basic difference between both procedures lies in extraction method while implanting process is almost same in both type of hair transplantation.
FUE is advancement in Follicular Unit Transplantation in which hair are extracted from donor area in the form of follicular units. Follicular units are group of three to four hair. A small needle punch is utilized to separate follicular units from the surrounding tissue and creates small circular incision in the skin. The follicular Unit is then extracted directly from scalp which leaves a small open hole. Then, follicular units are placed onto recipient sites.
Follicular Unit Transplantation (FUT) involves extraction of strip of hair and tissue from back of the scalp. The, hair transplant surgeons dissect hair bearing strip into individual follicular units. The dissection is done under fiber optic equipped microscopes to prevent the application of heat to the grafts. Then, they are implanted onto bald region where the surgeon has made recipient sites. The suture or staple are used to close the wounds.
FUE has a number of advantages over Fut Hair Transplant as it does not result in linear scarring. The healing time is fast. With minimally invasive nature, it produces hundreds of tiny scars in the donor area that are hard to detect.
FUE hair transplant is the most refined approach to hair transplantation and best for those who want to wear short hairstyle or scalp is too tight or has existing damage. Pain and discomfort in FUE after the surgery is less as compared FUT hair transplant.
FUE can be repeated after one month but FUT cannot because it takes much recovery time. FUE is length and time consuming process and requires experienced and trained hair transplantation surgeons and standardized instruments.
