response: I couldn't really say, but they would dye it by washing it in lime.
original_response: They used to do this naturally by washing it in lime and combing it back.
history: Have you ever colored your hair? I made mine purple once as a kid! That's interesting! The main reasons people dye their hair is to cover gray or to make it seem more fashionable, or just to restore the original color. Yeah, I did it just to make it look neat! Coloring hair can be done by a professional or at home, was yours done at home? Yeah, I was just a kid doing something dumb. I messed mine up royally as a kid, it is worth the investment for a professional! Celtic people used to dye their hair blonde. is that right? that is interesitng, I wonder why!
knowledge: Their hair is blond, but not naturally so: they bleach it, to this day, artificially, washing it in lime and combing it back from their foreheads.
