In Diana Gabaldon's "Lord John and the Hand of Devils," the character Grey's hair is described as resembling his mother's. It is fair, thick, and slightly wavy, highlighting a family resemblance. The disarray of his hair often requires it to be kept tightly restrained, a condition that reflects the influence of Tom Byrd's preferences.

This detail not only illustrates Grey's physical appearance but also hints at the controlling nature of his relationship with Byrd. The need for order in Grey's hair symbolizes the expectations placed upon him, showcasing a deeper connection between appearance and personal identity within the narrative.
