I voted "other" because I have fallen in love with the Nature Fusion conditioner - the one with Cassia in it.
I have not yet used henna or cassia, but from the few times I have used this conditioner, I have actually noticed that my hair is stronger. The difference is enough for me to use it directly after porosity control for the kind of moisture I am needing.
The slip is ridiculous for my 4a/b hair, and I have no moisture issues between washes.
That's my vote...
