Blue-black hair, also known as "raven hair," is the natural, darkest shade of human hair. The pigment eumelanin gives it its distinctive deep, bluish-black hue, often seen in East Asian, Native American, and Southern European populations.
This hair color has been associated with strength, confidence, and sophistication throughout history. Its benefits include low maintenance and resistance to sun damage. Notably, in ancient Egyptian culture, blue-black hair was considered a symbol of youth and vitality, adorned by both men and women.
