I wouldn't touch shea butter haircare products with a ten foot pole, it doesn't absorb, can be sticky and can build up. Love it for skin tho. Castor oil can also be quite sticky, I like it as a minor ingredient because it's a rare oil with humectant properties but I would be wary as a main ingredient.
Personally I prefer penetrating oils in conditioner form which are easy to distribute and easily removed, but I do have wavy caucasian hair and co-wash so can take rich but not heavy products if you can see the difference. You might get away with heavy products if you are low-pooing tho.
