Abstract

Iron is involved in many critical physiologic processes within the hair follicle, suggesting that iron deficiency could disrupt hair synthesis. However, studies of iron as a cause of hair loss have produced conflicting results. Some of the discrepancies may relate to limitations of assays for iron deficiency. This commentary discusses the sensitivity and specificity of available tests for iron deficiency and presents practical guidelines for testing and supplementation.

摘要

铁在毛囊内的许多关键生理过程中都有涉及，这表明铁缺乏可能会扰乱头发的合成。然而，关于铁导致脱发的研究结果却相互矛盾。一些差异可能与铁缺乏症检测方法的局限性有关。本评论讨论了现有铁缺乏检测方法的敏感性和特异性，并提出了检测和补充的实用指南。
