Alopecia Areata (AA, Patchy Hair Loss) — Causes and Treatment
ثبت نشده
چکیده
Alopecia areata is a non-scarring hair loss disorder that can occur in any part of the body, ranging from a small patch to complete loss of hair, without significant age or sex predisposition. Although the exact etiology is unknown, several patient-specific genetic, immunological, and environmental factors have been implicated. The underlying pathology is probably peribulbar infiltration of CD4+ and CD8+ cells around the hair follicles. No universally effective treatment exists, although topical or intralesional steroids and other medications, such as minoxidil and anthralin, are usually administered. Psychological distress of the patient should also be addressed by counselling and/or other measures.
