My favorites are pure virgin coconut oil, Queen Helene's Ginseng Cholesterol. These worked the best but please contribute what works for you.
Inecto Pure Coconut conditioner. *loveeyes*
It smells so gooooood and knots just slip out of my hair. The best part is that it isn't heavy and my natural wave and volume isn't pushed down.
Oh, and it's quite cheap, always a bonus.
