Will Wella color fresh cover that?

It should cover as it is a warm blonde, the remaining green may pull it more towards ash. Try on a strand test where it is greenest

Will try on a strandtest:) wonder if I can open and close Wella color fresh so that I dont have to use it all up in one go?

I'm guessing if you don't mix the dye and developer it might be OK. I'm not 100 percent sure though as I never use permanent dye.

Yeah, it'll be fine. As Martha says, as long as it's not in contact with the developer it should be fine.

Colour Fresh is a direct dye/true semi, so perfectly safe to open and just use some for a strand test.

The result was very very pleasing, it took my hair from whitey/minty to hay/ashydarkblonde however it did cause some ginger strands as the hairdye was flat out orange!!

Washed out very quickly, after first wash the green bits are coming back... I will cover them with the hairdye without diluting, as this shade of orange and my shade of green create quite a nice ashy shade,77

but what should I mix it with for the rest of my hair in order to avoid it going gingery? I got some blue/turquoise left over from directions, should I just mix it with that to take the edge off how orange the hair dye was? Or should I buy a lighter shade of wella colour fresh, i.e. the 10 something, which is essentially purple I think?

thanks for clearing up my confusion 😀
