I've his Volumizing Shampoo and Conditioner with Rose Extracts. There's not much lather but they work well. Initially I thought they were great for my fine hair, but after a while my hair went a bit 'fluffy'. But I've come to the conclusion that all volumizing haircare seems to do this though, so I tend to use them now and again rather than all the time. I too have coloured hair and noticed no colour loss when using them. Not much help I know...
I can now report that Christophe Robin hair products are the finest I have ever used.
The lemon masque is quite extraordinary when used properly (you tube video is great)
prickly pear conditioner, antioxidant shampoo & conditioner are also terrific & the
rose volume spray is lovely. All high performing products & can be used sparingly.
Besides Leonor Greyl, Philip B & Christophe Robin, IMHO, don't think there are
any better products to use for dry dehydrated highlighted hair.
