would it work ?

It depends what look you're going for. I can tell from my experience, after using semi perm purple dye mixed with lots of conditioner (cheaper than an actual toner), that the purple cancels out any warmth. I.e. if you got white hair, it wil stain it lavender, if you got light yellow hair, it will stain it light grey, if you got golden bits, they will go dark, natural blonde.

If you want platinum hair, then your hair is definitely too dark. But if You just want a natural blonde colour, go for it! People who want to get rid of copper tones in their brown hair, use purple as well, to get cool shades of brown.

Thankyou for your reply... im actually after a grey but dont mind a bit of lilac in there 🙂 i dont want white or platinum blond lol :).

I'd recommend purchasing directions' violet semi permanent hair dye, mixing it with sillicone free conditioner like tresemme all naturals, and voila! 😀

Brilliant .. i actually have both of those anyway! thats what i wash my hair with lmao.. and the last bright funky colour was violet...  lol

I don't think a grey/silver will be possible over hair that dark and orange. (Assuming the colour in the pic is accurate)
You can tone it to make it less brassy, but the orange will go an ashy brown at best. You need to be lighter and have much less warmth in the base for a cool toned grey/silver.
Did you have permanent dye in your hair before you bleached it? If so, a colour remover may help to get the orange out.

no it was a semi perminant reddish brown and voilet and a bit of blue.. okay girlies.. i think ill leave it for two more weeks then do a bleach bath to get the last of it out then tone 🙂 my hair is still in good condition but will keep using conditioner n the like 🙂

Semi permanent as in a direct dye or an oxidative one? (28 wash box dye) A colour remover still might help. If it was just a direct dye try some fading methods as well.
