I like the L'oreal ever pure range. Usually on 3 for 2 in Boots. Low sulphate (or no sulphate I can't remember) and its not loaded with silicones The conditioner is the only one rich enough for my coloured, dry, curly hair
I know it says it's for hair growth, but what it does is make your hair super-soft, silky, and manageable. It's often on 3 for 2 as well, or on 3 for £12. You use it in between shampoo and conditioner. It's marvellous.
Totally agree with brighthair, I use the L'Oreal Paris Hair Expertise (albeit the stuff for coloured hair that needs a bit of volume) and my hair has never been in such good condition since I started highlighting it.
