What about redheads?
if is natural red hair, than that's very beautiful, but if you or somebody else dye her/his hair in red, that's awful, out of fashion and very very damaging ..you better dye your hair in black than in red!
Many Israeli women dye their hair actual red and it doesn't even look like the red hair that is natural human hair. Natural red hair is actually more orange but many women in Israel dye it bright red. I think it's very unattractive.
If you meant by "dyeing one's hair" with unnatural colors like blue, green, purple, cool-aid red, funky orange...just unnatural colors...it wouldn't be a matter of choice for the woman to do that...(or a man)..it's a matter of that she's absolutely insane to even consider doing that.
However, if a woman wanted to change the color of her hair to a different NATURAL color...like black to brown or Brown to blonde hilights..or brown to reddish highlights, there shoudl be no problem with that.
