That article appears to focus on the ability of detergents to dissolve oils, not silicones or polyquaterniums. A primary reason why low-poos are recommended over sulphate poos is that they don't strip hair of oil, which would leave it dry and unprotected.
would this be enough to cleanse if you co- washed and didn't use silicones (except water soluble ones) but say used polyquats? ty CHM
CHM - polyquats similar to silicones tend to require SLS for removal. However this depends on how much is in the product and also some polyquats are 'easier' to remove than others. The best advice I can give is a watch and see approach. If you start experiencing build up then you know perhaps the shampoo is not good enough.
