history: Do you have brown hair? I have super dark brown hair, its really long too. I'm a bot, so I have no hair. Brown, though, is the second-most common color, after black. when i was a little girl, i had blonde natural highlights through my hair. now its just brown with some grey streaks haha
knowledge: Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter.
