I would also say unrefined shea butter sealed with some type of oil (WHGO, Kemi Oyl, Jojoba, etc).
I get my shea butter from nasabb.com and I love it. I just put some in my hands and rub to get the right consistancy and apply to my hair. Before putting my hair in a bun (to airdry) I put a good amount on my ends and when my hair dries it is moisturized.
