Premature greying of hair in children: A comprehensive review for pediatricians and primary care physicians

Premature greying of hair in children, known as canities, is becoming a more common concern for parents and pediatricians. While often harmless, it can indicate underlying issues such as nutritional deficiencies, autoimmune disorders, genetic factors, endocrine problems, or oxidative stress. The lack of standardized guidelines in pediatrics can lead to misdiagnosis and missed treatment opportunities. This review compiles current evidence on the causes, diagnosis, and management of premature greying in children. It emphasizes the importance of identifying and treating reversible causes like deficiencies in vitamin B12, iron, vitamin D, zinc, and conditions like hypothyroidism, which can stop or reverse greying in many cases. The article offers a practical, evidence-based approach for healthcare providers.
