The latter 2 techniques are rarely used currently.Follicular units (FUs) are the building blocks of modern hair transplantation (follicular unit transplanting [FUT]).The 2 main methods of donor harvest are strip harvesting and follicular unit excision (FUE). The latter may be achieved using a variety of techniques and devices.Minoxidil or finasteride may arrest or partially reverse MPB and FPHL, so a trial of treatment is often appropriate prior to surgery, or concurrent with surgery.Additional innovations of potential benefit include bio-enhanced storage solutions and platelet-rich plasma (PRP)
