Purpose of review The current review will address the different causes of localized hair loss in infancy. The data presented here will provide clinicians with the latest understanding of different disorders leading to localized hair loss and will provide recommendations for further management of infants who present with alopecia. Recent findings Localized hair loss in infancy is common, but its underlying causes vary greatly. Alopecia in infants can be categorized into congenital, genetic, inflammatory, mechanical, and physiologic causes. Decisions regarding further management are complex, as they often involve not only cosmetic concerns, but also work-up of possible systemic medical issues related to hair loss. Summary Clinicians must be able to distinguish between the different causes of infantile hair loss so that appropriate work-up and further management can be pursued. Factors such as physical appearance, timing of presentation, dermoscopic exam, histopathology, and associated systemic features can help lead clinicians to the correct diagnosis in the case of an infant with localized alopecia.
