Hair loss and its management in children

Hair loss in children can cause psychological stress to the parent and patient alike. Alopecia can be classified into congenital and acquired. Commonly encountered causes of pediatric alopecia (tinea capitis, alopecia areata, traction alopecia and trichotillomania) are reversible if diagnosed early. Special note should be made of the extent and type of alopecia (scarring or nonscarring), any hair shaft anomalies and signs of inflammation. Diagnostic evaluation includes a bewildering array of age-old simple bedside tests (e.g., potassium hydroxide preparation) to state-of-the art accurate instruments (e.g., trichoscan). Systemic antifungal therapy is required for tinea capitis. Topical and systemic immunomodulators are currently being employed for treating alopecia areata. A holistic approach would include not just therapeutic intervention but also an active search for associated nutritional deficits, underlying psychosocial disturbances and behavioral problems, the latter two requiring counseling and behavior therapy. Children with permanent hair loss can be offered surgical hair transplantation or camouflage devices, such as wigs.
