Premature Graying of Scalp Hairs Treated with Ferrous Sulfate

In a study from 2013, an 11-year-old Korean male with a 1-year history of premature graying of scalp hair was treated with iron supplements, including ferrous sulfate, for 5 months due to a clinical diagnosis of iron-deficient anemia, indicated by low hemoglobin (8.4 g/dL) and ferritin levels (2.6 ng/mL). After the treatment period, the patient's hair color recovered to nearly normal black color, suggesting that iron supplementation may be an effective treatment for premature hair graying associated with iron deficiency. No commercial support was identified for this study.
