    why when you cross the 2 hairs

    the moment you try to break them up, you would see like they are "somehow connected", is that "static electric" ?

    Not likely... as far as I know, they would both have the same charge if it was a matter of static. If you examine hairs through a microscope, though, you'll see that they are composed of thousands of little scales like the underside of a snake. In your example, I suspect that the scales are catching on each other.
