Recommendations for shampoo or product for blond hair

[Imtoooldforallthis]

I have a mixture of grey(natural) and blond highlights and feel it often looks dull, if I use a purple shampoo it tones down the brassines but seems to make the blond darker and duller. Does anyone have any recommendations to brighten it up in between hairdresser appointments?

Anyone?

Shampoo-in colour from Superdrug. It's called colour effects or something like that

Thanks, I'll have a look at that.

I use John Frieda Highlight activating shampoo and conditioner, seems to brighten up the highlights and the " natural" parts too- although mine are mousey brown rather than grey!

Any sort of toner (including a purple shampoo) is actually depositing colour to counteract the oranginess, so it may make the blonde look darker.
You could switch from a purple shampoo to one that 'brightens' like a pp mentioned. And use the purple shampoo once a week or something to keep the brassiness in check.

Shampoo called White hot hair. Seems to have good reviews

Tried the White Hot Hair, didn't think much of it.
