Its kind of a sticky powder, almost like mini sea urchins, that cling to your existing hair. I tried it a few years ago when my MPB started to get to me (right before I shaved). The stuff was a different shade then my hair and looked obviously two-toned. I took it back and got a refund. It was probably better than spray paint, but not much. It looks like the guy in the video put some hair spray on afterwards to "hold" it all in place. I believe most hair sprays are liken to to a form of lacquer.
