response: That's nice. Once again, brown hair is the second-most common color.
original_response: My bad haha. I think so too, red hair is not nearly as common as brown or black hair but I wish it was.
history: I have brown hair. It is very common in human beings. In fact, it's second only to black hair in how common it is. That's what I said, haha. I wish I had red hair. I think it looks really cool.
knowledge: Brown hair is the second most common human hair color, after black hair.
