Lead-based chemistry was initiated in ancient Egypt for cosmetic preparation more than 4000 years ago. Here, we study a hair-dyeing recipe using lead salts described in text since Greco-Roman times. We report direct evidence about the shape and distribution of PbS nanocrystals that form within the hair during blackening. It is remarkable that the composition and supramolecular organization of keratins can control PbS nanocrystal growth inside a hair.
4000多年前，古埃及就开始使用含铅化学物质来制备化妆品。在此，我们研究了自希腊罗马时代以来文献中描述的一种使用铅盐的染发配方。我们报告了在头发变黑过程中形成的硫化铅纳米晶体的形状和分布的直接证据。值得注意的是，角蛋白的组成和超分子结构可以控制头发内部硫化铅纳米晶体的生长。
