After the liposuction is completed), patients will have, under a ring block local anesthesia (see further description below), a subcutaneous scalp injection of either Puregraft purified autologous fat or saline (no-fat control) followed by a separate second injection, of either ADRCs (available in two different doses),a visually-matched blood saline solution (fat alone control), or saline (no-fat control) in a 2:2:2:1 ratio.
