wipe it off with a drag

A guy in a salon just had his hair dyed and the dark dye had left a ring of dark around his temples and neck.
He suggested a remedy to remove the dye from the skin without harming the newly dyed hair:
apparently, if you put a moist towel into cigarette ashes and then rub it into your skin, it removes the dye from the skin but not the hair.....
(before using this technique, the stylist tried all the products designed to do this task)
(They all failed)
I stepped outside, lit a cigarette and held onto the ashes in a small cup.
Once inside with the cup of ashes, the client used a wet towel to dab the ashes up and proceeded to rub them into his forehead, ear-lobes and neck.
--It worked!
where there was once black dye framing his face was just slightly reddened skin.....

as he left, he gave another word of hair-color wisdom:
if you ever get a bad color, use Prell.
guess this shampoo will strip the hair of color.
(didn't test this one....)
