Orange brassiness happens when hair is lightened (or even just coloured) and the underlying warm orange pigment is exposed.
The part most people get wrong is reaching for purple to fix it. Purple cancels yellow, and it does that job really well, but orange has a different opposing colour. That colour is blue.
A blue toner will help to neutralise (cancel out) that orange properly. You'll be left with a cooler tone in your hair, without having to do another round of bleach.
Every toner in this collection is blue-based and chosen for exactly this job. No guessing, no purple shampoo sadness.
