abstract: An extremely rare case of numerous oral hairs in a 13-year-old boy with alopecia areata is presented. The hairs growing from gingival pockets were black in color, similar to the hair on the patient's scalp. Microscopic examination of hairs from the oral cavity and those from the scalp showed differences in their structure.
