Hair transplantation is the most common cosmetic procedure in the United States nowadays despite the fact that it is expensive. Usually, patients need more than one session to receive a cosmetically acceptable result and patients need to be understanding and have realistic expectations. Although most of our patients are males, females represent about 10-15% of our new patients.
