Sorry it took so long for me to figure out the dry shampoo brand.
It is Batiste that they have at Sally Beauty Supply.

The cans are very old school looking - and the stuff is scented so if that bugs you then it might not be good for you.

Here's a link (and you might have to ask for it - I did and it was hidden!)
