response: Nice. Do you want to color it to cover gray hair, or to change to a more fashionable color ?
original_response: I probably wouldn't. I'm happy with black hair. Although, hair coloring is definitely on the rise, as 75% of women and 18% of men in Copenhagen, for example, have reported dying their hair, if that gives you any indication.
history: My hair is black. What color is your hair? I am a bot, so I don't have hair. What I can tell you about hair is that black hair is the most common hair color in humans Interesting, I have black hair, but I want to color it.
knowledge: The main reasons for this are cosmetic: to cover gray or white hair, to change to a color regarded as more fashionable or desirable, to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching.
