I tried this on as part of a Dior make-over... my hair was down (on the sides of my head, just in it's usual style), and the make-up artist got it on the hair near my temples... it made my hair so sticky, I chouldn't comb my fingers though it. Using a wet cloth to get it out didn't work. I ended up having to wash my hair later that day.
The Dior Airflash that got on my face worked okay, although the mist wasn't as fine as I would expect (i got more of a light 'spackling' vs. a smooth airbrushed look). Some got on my eyelashes and eyebrows which had to be wiped off...
Maybe I got a defective can, but I have still concluded that I will not use this product again.
