LuX for LUXuriously shiny hair?

What on earth? Last weekend when I was in Tokyo, a lady asked me to get some photos taken at the 'shine testing' booth. I obliged and had these two pics taken...the card makes no mention of the shine condition of my hair.

So I left, baffled, wondering what the heck the photos were taken for. Beats me! Anyway they asked me if I ever used LUX shampoo to which I replied, 'yes' and they thanked me graciously for my business and presented me with some samples.
