Sensor to detect the movement of hair that is hung from the ceiling

I am making an installation with hair. The hair, one by one, will be hung from the ceiling, covering a space of 290 cm x 290 cm. I need a sensor that can detect the movement of the hair, either by touch or wind. I realize that most touch sensors work only when they are touched by something with a wet surface. I need a sensor that can detect the movement of the hair whether it is touched or not. Would you tell me if there is a sensor for this purpose?

As a total beginner, I have no idea of what arduino tools to buy. (I learned arduino very briefly, when I was studying computer art in school. I can understand simple coding, but I don't know anything about the material parts of arduino.) Would you give me some guidance on this? Thank you.
