Please could someone give me some advice, i want to put a toner on my blond high lights as they have become brassy. i was advised to use wella, so i have bought the toner but the wella developer i can't buy without ordering, and i really need to do it sooner. can anyone tell me if its ok to use any other developer so i dont have to wait for the wella one??
Many thanks Nadine
