Definition
"Light-haired" simply describes someone with hair that is of a pale color, such as blond, light brown, or light red. It's a general descriptor focusing on the lightness of the hair, not a specific shade. It lacks the potential for gendered connotation that 'blond' and 'blonde' might have. Consider it a broad category, like saying someone has "dark eyes" instead of specifying "brown" or "black." Hair color is simply a descriptor of appearance.
