Alopecia areata is an immunologically mediated disease characterized by extreme variability not only in the time of initial onset of hair loss but in the duration, extent and pattern of hair loss during any given episode of active loss. These variables, as well as the unpredictable nature of spontaneous regrowth and lack of a uniform response to various therapies, has made clinical trials in alopecia areata difficult to plan and implement. In fact, there are currently no drugs FDA-approved specifically for the indication of alopecia areata.
