response: Well actually the darker a person's hair color is, the more individual hair follicles they have on their scalp as well!
history: I just brown hair.  I wonder how many people have brown hair. Next to black hair, it's actually the second-most common hair color. Is there a reasons so many people have brown hair? I don't know why large numbers of them do, but I know that in general eumelanin controls how dark hair is. The more there is, the darker the hair. Does the color of the hair change anything else about it?
knowledge: The darker a person's natural hair color is, the more individual hair follicles they have on their scalp.
