How do I stop my highlights going brassy?

[5000candlesinthewind]

I've tried provoke and left it on for a few minutes but by the time I'm coming towards getting fresh roots it is still starting to look a bit brassy.

What else can I do?

I only do it once a month to be fair. My hairdresser has sent me baby blonde despite showing her a photo and saying not that so I have the opposite problem right now tbh

MassDebate my scalp turned lilac

😱 holly!

It has a little sensor inside the shampoo five. Very clever stuff.

I wouldn't mind lilac hair, but thanks for the warning!

Purple shampoos tend to "wash out" the lowlights faster than they would otherwise so I would only use them to stretch out the last couple of weeks before the hairdressers holly.

I have overdone it before and ended up a bit Liliac a wash with anti-dandruff shampoo just sorts the issue
