The Islamic Sheitel?

From Michael Totten's blog (quoting Amir Taheri):

To counter the Islamist claim that the hijab blocks the dangerous, lust-provoking rays emanating from a woman's hair, some women have proposed other forms of hijab. One Iranian designer came out with a wig made of horsehair, thus ensuring that a woman's own hair remains hidden while she still "looks like a normal human being."
