response: The thing is, it can vary, so there's light brown as well as almost black hair.
original_response: You must not be a female.. lol I mean brown varies from light to dark, but I prefer blonde
history: I used to have bright red hair but as the years have gone by it has become more brown. Interesting, are you aware that you have the second most common hair color now? I wasn't but it doesn't concern me too much, I wonder if it can go black too from brown.
knowledge: It varies from light brown to almost black hair.
