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.
That's nice. Once again, brown hair is the second-most common color.
I think red hair is mostly present in northern climates. It is pretty rare where I live.
Oh, that's interesting. As for brown hair, it can vary from light to almost black in shade.
Mine is on the lighter side. The sun makes it look almost blonde at times.
