Oddly enough it was black hair dye. (I wouldn't think that would alter the hair color of most Middle Eastern types.)

Maybe the black hair dye was a cosmetic improvement, you know, to look good for the 72 virgins.

Maybe they don't use the dye to do their hair???

I can't imagine what else the creeps would use it for but the Good Guy's have been telling us to think "out of the box." ;)

You assume that hair dye is only for hair. There may have been other things they wanted to dye, or the dye may have had some interesting chemical properties.
