We performed a literature review according to the modified PRISMA guidelines, using a combination of relevant key words in electronic databases. According to the data from the 25 articles on BAA reviewed here, BAA mostly affects middle-aged men (mean age 31 years) who typically experience patchy hair loss in the neck region, which spreads to the scalp within 12 months. Similar to AA, BAA is associated with autoimmune diseases such as <i>H. pylori</i> and thyroiditis; however, BAA has no clear genetic pattern of inheritance which is observed in alopecia areata. Common dermoscopic findings in BAA include vellus white hairs and exclamation mark hairs, which may help distinguish it from other pathologies affecting facial hair.
