Abstract
To the Editor: Alopecia is associated with abnormalities in thyroid stimulating hormone, ferritin, zinc, and vitamin D.1,2 Despite limited evidence of improved hair growth with supplementation, treatment of nonscarring alopecia frequently involves laboratory testing and empiric repletion.3 To our knowledge, no study has evaluated the relationship between supplementation and hair growth in individuals using baseline and follow-up laboratory data. The purpose of this study was to characterize the impact of supplementation on hair growth.
