Demographic Characteristics and Association of Serum Vitamin B12, Ferritin, and Thyroid Function with Premature Canities in Indian Patients from an Urban Skin Clinic of North India: A Retrospective Analysis of 71 Cases

The study retrospectively analyzed 71 cases of premature canities (graying of hair) in an urban skin clinic in North India, focusing on demographic characteristics and associations with serum vitamin B12, ferritin, and thyroid function. It found significant associations between low levels of serum vitamin B12 and ferritin with premature graying of hair, while no significant correlation was observed with thyroid function. The findings suggested that nutritional deficiencies might play a role in the early onset of hair graying, highlighting the need for further research to explore these associations.
