L’OREAL Effasol Color Remover 0.86oz/22.11g (Quantity: 1 Application)

can someone advise how to use this powder. No instructions. What do i miss it with. Thanx

My hair is dyed dark brown but now it is very faded and is a awful orange tone. Will this remove the faded dye?

Will this remove permanent blue? i dyed my hair a mercury blue by live and i’m wanting a way to get it out so i can dye it brown.

Will this remove bright teal/green in one go? I am going crazy trying to remove this after using colour b 4 over directions purple?
