I use Giovanni Smooth as Silk shampoo. It contains amodimethicone lower in the ingredient list and it also contains cocamidopropyl betaine slightly above. I have read that cocamidopropyl betaine washes amodimethcione out. Does the cocamidopropyl betaine in the shampoo counteract the amodimethicone or do I still need to clarify to get rid of the amodimethicone build up?
