Alopecia areata (AA) is suddenly occurring, non-scarring hair loss disease. There are many theories, and many implied factors, but the true pathogenesis of AA is still not clear. In this review we discuss therapy of AA, topical, systemic and biologics. Few cases are presented with dermoscopic (trichoscopic) view of the scalp, and use of trichoscopy in prognosis of AA. This is a completely benign condition, but devastating for a patient and requires multidiscipline.
