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.
No, I've never dyed my hair, but I've been thinking of doing it recently, due to my gray hair.
Have you ever colored your hair? I made mine purple once as a kid!
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.
