No, if your hair in the back of your head is long enough during the procedure, harvesting using NeoGraft/FUE can be performed by shaving small hidden donor areas, which your other existing hair can cover. A buzz-cut style is recommended in the donor area for maximum yield or transplanting larger numbers of grafts.
