Giovanni conditioners. I use them to co wash and as a leave in. I bought 2 gallon sized bottles of Giovanni conditioners from
www.massagewarehouse.com back in April/May and I'm still on the first bottle.
They are cone free and have great slip and are very moisturizing. Right now I'm using the Smooth as Silk Deeper Moisture conditioner and the 50:50 Hydrating Calming conditioner (not at the same time). I find that the Giovanni condioners pretty much work the same. I just read the ingredients to make sure cones aren't included.
When I did use cones I used Aussie Moist and Herbal Essence Hello Hydration conditoners. Both of them were moisturizing and had excellent slip. They also had similar scents and ingredients.
