touch of silver shampoo

[MrsNutkin]

I have had my hair highlighted, the hairdresser said the golden highlights may go a bit brassy in a few weeks and suggested I return for a toner but I know Shampoo's exist that do this kind of thing.
Is touch of silver twice a week maintenance shampoo safe to use on brown highlighted hair?
Thanks :)

I got my hair recently highlighted a real light blonde and I use a purple shampoo once a week. I bought it from Lush.

I know the one you mean... Daddy - O. Does it do anything to the non highlighted bits?

thanks for replying
