Back2Natural is a great product. To be clear, you can also use normal conditioner on your system; just keep it off the base and the knots. If you have a polystyrene wig head or something similar, put the system on it, spread some conditioner on your comb, and comb it through through the hair, keeping it on the top layer and not delving down to the base. It's easier to do this is the conditioner is thick and creamy rather than liquid. When you rinse if off, turn the hairpiece base side up, so that the water is running through the base first and then the hair, so the conditioner is being washed away from the direction of the base and knots.
