You can use 8.3 fundamental white box and that will cover white hair , using 8.3 the yellow box won’t cover also make sure you mix with the inoa developer xI normally use Wella but just need some advice on using Inoa L’Oréal. Does 8.3 cover grey on its own or does it have to be mixed with the fundamentals . Tia
