The recipient site (where the hair grafts are placed) does not have to be shaved for the procedure or implantation of follicles. The donor site for Neograft/FUE needs to be cut very closely but not necessarily shaved in order for the punch to be placed over the hair follicle itself and be extracted. Once the small crusts or scabs have come off, the recipient/grafted area looks like it did before the procedure. For most patients, it will take months to notice new hair growth in that area. The hair around the donor site follicles will grow at their normal rate.
Whether you need to shave the scalp depends on whether you are speaking about the donor or recipient area.For FUE (follicular unit extraction) techniques, where hair is taken from the back of the scalp "one-by-one" the donor area is shaved (or at least a portion of the donor area is shaved).For the recipient area, this particular area does not necessarily need to be shaved.
