I've never heard of the pre-wash.
I've been using the Restorative Treatment (that comes in a tub) for years. It is also CG, no cones (you have to check because some Ojon products have cones).
I also buy it on Ebay and it lasts a long long time. I use it in my deep treatments, and also run a bit through my hair when it's feeling dry, especially in winter.
I will have to compare the ingredients!
