Best shampoo and conditioner for coloured/highlighted hair?

[Ginandbearit1]

I have highlights and colour, I've tried lots of 'blue' shampoo/conditioner, Kerastase and Aveda. I find they can be quite drying.

Does anyone have any recommendations that leave hair shiny/glossy and not dry? Cheap or expensive. At the moment I'm alternating between Aveda Blue Malva and Tresemme.

i like redken colour extend, you can usually find offers online.

I really like this one. It's very rich for my damaged ends - www.superdrug.com/Hair/Shampoo/Everyday-Shampoo/Pantene-Hair-Biology-Full-&-Vibrant-Shampoo-250ml/p/782533

I just use a purple shampoo once a week either Elvive or I get the Fanola one from my hairdresser
