Alopecia: Children Are Not Just Little People

The document from 2015 highlights the differences in diagnosing and managing alopecia in children versus adults, noting that the most common cause of non-scarring hair loss in adults is pattern hair loss, while in children, it is tinea capitis. It emphasizes the importance of a thorough history and physical examination, including dermatoscopy, to distinguish between conditions such as alopecia areata, trichotillomania, and tinea capitis. Scarring alopecias are more common in adults and require biopsy for classification. The workup for alopecia in children tends to be more clinical and less invasive, with management and prognosis varying by age and type of alopecia. Early treatment generally leads to a better prognosis, though alopecia areata has an unpredictable course. The document also stresses the emotional and psychological impact of alopecia, the need for support and education for affected children and their families, the role of support groups, and the importance of psychological support for patients with trichotillomania.
