Just using a leave in usually gives shine for me since my hair is dark. Abba nourishing conditioner seems to leave a lot of shine.
Curl Keeper adds shine also although it's mostly for frizz.
Clear gels help with shine since ones with color tend to dull my hair somewhat.
2c/3a?
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
