What's the best shampoo/conditioner?

[JingleBelleDameSansMerci]

Let's say that money's no object (or I could just admit that I'm excessively vain about my hair and will justify any expense) - what's the best shampoo/conditioner for thick hair (ie lots of hair - not coarse hair) that's mostly grey underneath all the professionally applied colour?

I've tried:

Kerastase in various flavours and I don't like it much;
Paul Mitchell but not recently.
Lee Stafford - various.
Charles Worthington - various.

And so on...

Pleeeeeeeeease help me to find something that will keep my hair soft, silky and shiney.

JingleBelleDameSansMerci don't worry it was your thread and as long as you got sorted it doesn't matter.
TattytinsellooksDevine gave me some good advice. By the way TTLD bog standard shampoo and conditioner- I am a tad dumb here.
Would anti frizz john freida one be good? Or just use the serum? Do I buy for normal hair or limp hair? Its fine but the frizz and poor wave make it look like I stuck my fingers in a plug socket.
Also dry shampoo I've used Baliste, seems good for me. Any advances on that?

L'Occitane - the ones with the esential oils and minimal SLS, and the Dr Organic ones from Holland and Barrett.

Tried the Moroccan Oil shampoo and conditioner and it made me want to rip my scalp off it itched so much.

But Moroccan Oil itself is great
