There are two techniques of hair transplant
FUE is a hair transplantation method which involves taking the individual hair follicular grafts from the back of the head. Follicular grafts are cut one by one through a small specialised machine and are removed. This process is tedious and takes a few hours to complete.
Hair grafts may also be harvested from beard and chest. Procedure is done under local anesthesia. It leaves very small scars, less than a mm. So stitching is not required. Recovery is fast in this method.
FUT is the oldest hair transplant technique in which a thin strip of skin is removed from the back of the head surgically. The hair follicles are then divided into individual units. The donor area is then stitched together.
FUT technique leaves a noticeable scar on the donor area. Hair follicles are implanted by creating reception incisions or holes in the treatment area and placing hair follicles with forceps. Stitches are removed after 10 days.
