Background and Objectives: Greying of hair is a regular feature of chronological aging that occurs in all regions and races. Premature canities is defined as minimum of five grey hairs in a person less than 20 years in Whites, 25 years in Asians, and 30 years in Africans. Premature canities is a common yet incompletely understood dermatological entity. This study aims at finding any association between premature hair greying (PHG) and parameters like hemoglobin (Hb), ferritin and calcium levels as well as its clinical profile. Methodology: This was a hospital-based cross-sectional analytical study conducted in the Department of Dermatology and Venereology, Trivandrum over one and half years. The study population consisted of 40 cases and 40 controls. Severity assessment, calculation of body mass index, and estimation of hemoglobin, serum ferritin, calcium, Random blood sugar, Anti Thyroid Peroxidase antibody, T3, T4, and TSH were done. Results: The mean age of the 40 patients was 17.14 years and most patients had onset of greying between 16 and 20 years. The male to female ratio was 1.2:1. A positive family history with a paternal predominance was noted. Vertex was the most common site of onset (42.5%), diffuse pattern was the most common clinical pattern (47.5%) and 60% had involvement of mild grade. Fourteen patients (35%) had abnormal investigations reports, in terms of low ferritin levels in 7 (17.5%), low calcium in 4 (10%) and a low Hb levels in 3 (7.5%) patients. Six (15%) patients had raised Anti TPO values. The association of PHG with low ferritin and raised anti-TPO levels were statistically significant. Conclusion: Low serum ferritin and raised Anti TPO levels may have a role in premature hair greying.
