I'm 3c.
The love of my life is Elasta QP Mango Butter.
I hate Shea Butter for my hair. It is too heavy, doesn't absorb well so it stays greasy and very oily, even when I use it on wet hair, and gives me the look of dandruff since it doesn't absorb and dries in light colored flakes after it melts a little.
The only product I can use with shea is Cantu Shea Butter Leave In Conditioner, and even that I need to use sparsely, though not solely because of the shea.
