From time to time I'm asked, what's the difference between follicular unit transplant and follicular unit extraction?  In Follicular Unit Transplantation the hair for relocation is obtained by surgically excising a strip of hair bearing skin from the donor region of the scalp.  The skin edges of this wound are then sutured closed and the result is typically a thin, fine line scar oriented horizontally across the back of the head.  Follicular Unit Extraction or FUE is a contemporary revival of an antiquated technique of obtaining donor hair in which a small circular cutting instrument is used to harvest follicular units one at a time from the donor area.  Each harvest or extraction creates a small circular scar and a transplant session creates a number of discontinuous, individual scars contrasting with the continuous liner scar of FUT.  Short hair styles are well supported with either method of harvesting.  Large session sizes are much more easily accomplished utilizing FUT technique and costs for FUE are often quadruple the cost of FUT on per graft basis.
