Redheaded describes someone who has red hair, which ranges from bright copper to deep auburn to strawberry blonde. Only about 2% of people worldwide are naturally redheaded, making red hair the rarest natural hair color.

Red hair comes from a genetic variation that affects how the body produces pigment. It's most common in people with Scottish, Irish, or northern European ancestry. The same gene that creates red hair often causes fair, freckled skin that sunburns easily.

Throughout history, redheaded people have inspired strong reactions. Ancient Egyptians considered red hair unlucky, while Queen Elizabeth I made auburn hair fashionable in England. Viking warriors supposedly prized red hair as a sign of strength. Today, fictional redheaded characters like Anne of Green Gables and Pippi Longstocking are beloved for their spirit and individuality.

People sometimes use redhead as a noun to refer to someone with red hair. The informal term ginger also means redheaded, though it can be rude or hurtful depending on how it's used. Many redheaded people take pride in their distinctive appearance, and some cities even hold festivals celebrating red hair.
