Comparative Study of Trichoscopic Features of Alopecia Areata Between Adults and Children and Between Different Body Parts (Scalp, Beard, Eyebrow, and Moustache)

This study involving 90 patients (50 adults and 40 children) examined the trichoscopic features of alopecia areata (AA) across different age groups and body parts. Key findings include that children more frequently exhibit honeycomb pigment patterns and Pohlpinkus constriction, while adults show more tulip hair. Scalp lesions commonly display empty follicular openings and honeycomb pigment patterns. AA recurrence is more prevalent in adults, with no significant differences in gender or family history. The study underscores that trichoscopic features, such as yellow dots and short vellus hairs, vary by age and body location, providing valuable insights into AA's progression and potential treatment strategies.
