You might want to try shealoe. Shealoe is shea butter whipped with aloe so it has the properties of shea but it's lighter and fluffier.
Of course, my personal favorites are avocado butter, it's heavy though, and hemp seed butter, a little lighter than avocado, very nourishing.
Macadamia nut butter is more expensive than the previously mentioned butters but it's rich without feeling too heavy or greasy. It "soaks" into my hair quickly and gives a nice shine, leaves hair feeling like silk.
If you're feeling adventurous, pure mango butter (very hard like shea or cocoa butter) melted down and whipped with virgin coconut oil is a real treat for the hair. It has all the moisturizing properties of coconut oil and mango combined.
The key with all butters is too not use too much. Start out with a tiny bit and slowly work your way up.
