When you go totally CG, you really can't use any silcone products at all, because they build up, and can't be removed without using sulphate shampoo. I think the principle behind CG isn't the 'cone problem as much as the harsh drying sulphates needed to remove (although some find cones drying too, not me though)
This means looking at the ingredients in your conditioners, to check for anything ending in 'cone', dimethicone is a common one, or, xane<<<a nasty one. I think its spelled cyclopentasiloxane, it has been referred to as 'liquid latex'.
Some CGers use a 'low-poo', meaning the shampoo doesn't contain sulphates like sodium laureth sulphate, rather a more gentle cleanser such as coco-betaine. This kind of shampoo will remove water soluble 'cones, such as amodimethicone, or any cone with 'PEG' attached to it. It won't remove the other type of cone though.
Right now, my hair is dreadful, I've had some time off from CG, and its dry and ratty. When it was at its best, I was using a tea tree conditioner for washing, a peach supermarket brand conditioner mixed with a little honey for condtioning, and Boots curl creme under gel for styling.
At the moment I'm trying to rescue it, I've neglected it and its making me pay LOL
Hope this helps, feel free to ask about anything I didnt make clear, I'm not as knowledgeable as some of the ladies here, but I've learnt a lot since joining this forum.
