AbstractAlopecia areata (AA) is a frequent autoimmune disorder in which inflammatory cells attack the hair follicles. AA affecting the beard area is well known and is referred to as alopecia areata barbae (AAB) when involvement is limited exclusively to the beard. Currently, no guidelines are established for specific therapeutic approaches for this condition. We present a case of a healthy 30-year-old male suffering from AAB. Three injections of platelet-rich plasma (PRP) with six-week intervals were applied. Stabilization of the condition was noted at the first follow-up (before the second injection), initial minimal hair regrowth was noted at the second follow-up (before the third injection) and robust regrowth at the one-year follow-up. To our knowledge, this case is the first report of a successful treatment of AAB using PRP. PRP represents a new, safe and potentially effective treatment option for AAB. More studies will be necessary to determine the efficacy of this treatment compared to conventional therapy.Copyright © 2020, Pototschnig et al.
