Almost every patient will develop some swelling because it is a normal part of the healing process. It will almost always occur with procedures where the hairline, temples or frontal areas are transplanted. But if your procedure is only on the crown, you are not likely to get any visible swelling in the face. In any case, swelling will start in the forehead, and slowly move down the face with gravity. The eyebrow area will swell and then the lower eyelids can also follow. The use of prescription steroid tablets can really help the swelling to be as little as possible and to disappear within 4-5 days. Certain other medical conditions can lead to longer swelling and/or bruising, so always discuss with your surgeon. Hope this helps!
