The Clairol one I regularly use is out of stock on Amazon, Boots. Superdrug & various online chemists as well as Asda and Sainsburys. I am guessing once one store gets it in, the others will too - anyone else finding this? I wonder if perhaps it is imported so we've run out in this country and don't want to try another brand even if I could get it, as I don't want to risk another colour - I only do the roots.
