Trichoscopy of Alopecia Areata in Children: A Retrospective Comparative Analysis of 50 Children and 50 Adults

The study compared trichoscopic findings in 50 children (3-11 years old) and 50 adults (19-31 years old) with alopecia areata. It found that yellow dots were less common in children (52%) than in adults (96%), while pigtail hairs and empty follicular openings were more common in children (28% and 80%, respectively) compared to adults (4% and 32%, respectively). Other trichoscopic features showed no significant differences between the two groups. The most common findings in children were empty follicular openings and short vellus hairs, and triangular hairs were identified as a new finding in alopecia areata.
