I know some of you will mention Hindu women. Indian culture was influenced a lot by the Islamic occupation.
And I know there are some ultra radical sects of Judaism and Christianity that do it, but in general, you don't see Christian, Jewish or Buddhist women just walking around in the street with their hair covered.
So if you wanna make the argument that it's a personal choice, it's only a personal choice for MUSLIM women. It almost seems as if the Islamic religion sexualizes hair. Because I've never heard of any other group of women saying they cover their hair to be modest and avoid sexual harassment.
