I got a can of Bastiste for Christmas and have been using it on my non-shower days since then. My hair is very fine and straight so oily roots become very noticeable the day after washing.
For the most part, I haven't had any problem with the dry shampoo. It's easy to use and helps my hair tie grip in my hair better, but I did discover once that there ended up being quite a bit of white powder on my clothes. I may have just been a bit over-enthusiastic with the spraying that day but have been more cautious ever since.
I love this product! It's great on day 3 when my hair needs a perk up. It absorbs the excess oil and leaves hair feeling nice and dry. It does need a quick comb through to stop leaving the white dusty look behind. It doesn't hurt to have nice clean fresh scent either!
Tips: Great to use even when you need a little extra volume in freshly washed hair.
