Red hair genetics is the study of the genes and traits conferring red hair color, officially recognized as a shade falling between auburn and orange. When we're not referring to a hair dye substance, red hair is a naturally occurring human hair color variant, with individuals of Northern or Northwestern European ancestry most likely to possess it.
Beyond its aesthetic significance, red hair genetics offers insights into human diversity, genetic inheritance patterns, and the evolution of physical attributes. It also has great implications for medical research on pigmentation disorders and personalized medicine.
