Im going to be doing my friends lights during the week she had an all over colour done (not with me) and now she has like an orangy band she want to go back to lights so i was thinking of doing 1 pre-lighter and 1 12/1 (wella) which is a high lift ash blonde to try neutralise the brassiness am i going in the right direction?? i might use a toner yet i'll see how it turns out first thanks
