response: That makes sense. Did you have a specific reason for dyeing your hair? I know people do it to cover gray or white hair. or to just make their hair more fashionable.
history: Right now I have bright purple hair! Nice! Did you change your hair color by dyeing it? Yes, I had it professionally done. I know that you can do it at home independently. Have you tried that before? I have done that in the past but I didn't want to mess it up.
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.
