What was done
A narrative literature search of PubMed and Google Scholar was conducted in July 2018 to compile and summarize published articles evaluating the relationship between micronutrients (vitamins A, B, C, D, E, iron, selenium, and zinc) and non-scarring alopecia.
What was found
The abstract reports no quantitative data or specific numerical results. It notes that micronutrients play an important but not fully clear role in follicle development and immune function, and that current evidence on supplementation is conflicting.
Why it matters
It outlines the biological rationale for micronutrient involvement in hair cycling while clarifying that clinical evidence remains insufficient to routinely recommend supplementation without proven deficiency.
Limits
This is a narrative review with no systematic inclusion criteria, risk-of-bias assessment, or meta-analytic data. The abstract provides no study counts, participant numbers, or nutrient-specific effect sizes.
