How much of rinse out conditioner I can use as a leave-in? Somehow I am not very convinced about using something that is supposed to be rinsed.. What are the ingredients that you shouldn't leave in your hair?

I don't like this non-brushed look at all! It makes my roots look dirty eventhough they aren't..

Assuming the product is CG friendly no specific ingredients should not be left in your hair they are all fine. The amount you use depends on your hair type and the specific product, use enough to start clumping and get a squishy 'seaweedy' noise.
