I have both in my stash and the Pantene 2 in 1 Shampoo and Conditioner has SLES as surfactant and Dimethicone and Dimeticonol to condition the hair.
So it's IMO a harsh Shampoo with heavy silicones.
My Elvive Cleansing Conditioner is sulfate free and has only Amodimethicone in it. It doesn't cleanse very well and is much gentler.
