Hi! Do you have red hair?
1_Wizard
Hey, I don't have red hair, but my best friend does. It's a very rare color to have. Do you?

I have red hair. It is very rare. Only 2% of the world's population have that color hair. 
1_Wizard
My hair is brown, apparently the darker the hair color, the more individual follicles a person has on their scalp.

Oh! I did not know that! Did you know that the viking population had red hair?
