Adolescence is a critical developmental period marked by physical, psychological, and social changes, and hair loss can significantly impact self-esteem. Delays in treatment are common, and they sometimes result in permanent hair loss. This article reviews the most common causes of hair loss in adolescents (eg, androgenetic alopecia, alopecia areata, telogen effluvium, traction alopecia, trichotillomania). Key diagnostic approaches include thorough history taking and scalp examination. Management strategies range from pharmacological management to lifestyle modifications and behavioral therapies. Early identification and treatment, patient education, and understanding indications for referral are crucial for optimal clinical and psychosocial outcomes. This review emphasizes the importance of a primary care physician's initial evaluation and management of adolescent hair loss. [Pediatr Ann. 2025;54(6):e189-e195.].
