7 Jan 2026 • Micronutrient deficiencies—particularly low zinc and vitamin D—emerged as key drivers of both tinea capitis risk and treatment response in children.

In a case–control study of 140 children aged 2–12 years with tinea capitis and 140 matched controls, zinc deficiency was linked to nearly a threefold higher infection risk (OR 2.87), while vitamin D deficiency doubled the risk (OR 2.11).

By week 8, clinical cure was achieved in just 44% of children with nutritional deficiencies, compared with 71% of those with adequate micronutrient status. Children with multiple deficiencies had more severe disease and slower recovery. Nutritional status further influenced how socioeconomic factors affected treatment response.

The findings highlight routine nutritional screening and targeted supplementation as practical strategies to improve outcomes.
