title: Clinical observations in alopecia areata: Implications and hypotheses.
abstract: Alopecia areata (AA) is a T-cell-mediated hair loss disorder but the exact cause is unknown. In this report we describe patterns of onset, regrowth and relapse in AA and propose potential underlying mechanisms. We believe that these aspects of AA require integration into modern theories of AA pathogenesis.
