response: Main reasons other than fashion would be hiding gray or white hair and restoring one's original hair color.
original_response: Thank goodness for small favors!  LOL Why did you want to color it?  For cosmetic reasons, to cover gray?
history: I just dyed my hair burgandy, kind of regretting it Oh wow!  Did you have it done  professionally by a hairdresser or did you do it yourself at home? I did it at home and obviously did not think it through, Burgandy is not a natural hair color so it looks weird Sounds unfortunate, although home coloring got 1.9 billion in the US back in 2011. Why is there so much hair coloring sales anyway? I understand it to be for fashion since that's what I tried but other than that I don't get 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.
