Shampoo & Conditioner coloured hair

[stillstanding51]

Just had lovely ash brown lowlights put through my bleach blonde and it looks great.
Im assuming it will lift pretty quickly so I’m looking to prolong the colour as best I can
Whats the best shampoo&conditioner to use to maintain the colour? Ideally from Boots
thanks

My hairdresser recommended the Colour Wow, I bought that but alternate it with the Aussie colour shampoo. I also have the Umberto Gianni Scalp Detox for dandruff/buildup in a yellow tube which says it is colour safe.

Ive heard good things about the L’Oréal metal detox.

I used to use the Aussie stuff, might revisit it
Funnily enough the stylist who cut my hair recommended Colour Wow for straightening
Thank you

I like TIGI Bedhead (Colour Godess).

It also smells divine.
