I'm a little late to this post but I'd like to add, as some ladies have indicated, not just the quantities of ingredients on the list are different but for me I notice a big difference between the Breakcure and the Leave In Treatment.... Breakcure for me makes a great moisturizer and leave in alone. However, with the Leave In Treatment in the tub I noticed that even when I added extra shea butter to it it just won't work as a leave in or moisturizer and feel kinda weird and coating. But I use it alone or mixed with porosity control and it's great as a deep conditioner.
So yeah, I noticed right away that the ingredients for alot of the products in this line are really similar but they perform differently for me. You just have to play with things to see what works best. HTHS!
