Hello! It sounds like your hair is naturally curly? With your hair bring short it should be less damaged than longer hair. Has your hair been colored?
Brushing it with a natural bristle brush will help to distribute the oil along the hair length and encourage the hairs to lie together, which will reduce the frizziness.
I brush mine before washing as that's when it's oiliest, then the hot wash takes off the excess oil.
I found my hair is never frizzy any more. The natural oils just does its thing.
Don't be afraid to keep experimenting, try changing something for a few days or weeks to see how your hair responds.
Good luck! Let me know how you get on.
