Hey guys. I use Koleston colours. I've come cross an Osmo blonde - 12/2 & I was just wondering if I'm right in thinking the '/2' is cool ash!?! I know '/1' is Ash & the rest of them, but I've never come across /2 so I'm just curious as I was thinking of using it on a client. It looks a more of a 'cool' blonde than the koleston 12/1! X
