Silicon Mix is like the ORS Replenishing Paks. They have protein, but they're just more of a moisturizing conditioner than protein. I used some silicon mix the other day for my DC along with a little bit of Aphogee EFAs and I had some very soft and luscious hair after rinsing it out. I don't know where I heard it from, but I heard that silicon mix is better when mixed with oils. It sure did alright by me!!
