I was using whipped unrefined shea butter for a couple of years. My hair liked it -- softened my crispy dried out ends and helped to calm canopy frizz. I used it overnight and would rinse out in the morning. Rinsed out well for me even with just WO washing.

I recently switched to coconut oil. I like it better than shea butter. Easier to apply (right now, my ccno is liquid since it's warm in my house with higher temps) and seems to sink into my hair better.
