The main concern during this procedure is bleeding. Many bleeding diatheses (platelet dysfunction and von Willebrand disease) manifest when the scalp, a highly vascularized field, is stressed during a transplant in which the donor sites are not frequently sutured. Many physicians recommend evaluating the patient's PT, aPTT, international normalized ratio (INR), and bleeding time prior to the procedure.

In general, the donor site and the recipient site need to be inspected for hair density, quality, and texture. After an estimation of the yield of grafts is made, the physician should discuss where and how the hair grafts will be implanted. Some hair grafts become dislodged overnight and can easily be reseated the next day. No exercise or heavy lifting should be performed for several days. The scalp dressing should remain intact overnight, and the hair grafts should not be washed for about 3-4 days. Ideally, all dressings should be removed by trained personnel only. Compliance with these recommendations ensures success of the transplants.
