I've just traipsed through boots looking for cg-compatible products.
Managed to pick up the fabled pink curl creme and a boots essentials gel (smells v nice - cucumber-y?); also managed, after some searching, to find silicone free conditioners, since even the water soluble 'cone in the Naked Rescue conditioner seems to make my hair feels a bit gunky.
My haul are Original Source Mint&TeaTree condish and their WhitePear&Avocado condish.
We'll see how they agree with my barnet.
Also noticed that a couple of the boots essentials and the ASDA essential care natural extracts conditioners are silicone free, not all of them though.

The other thing I've noticed - cg-compatible preoducts seems to be dirt cheap! PJ-ing without guilt????
