Greasy scalp, perfect ends

My hair is somewhere around 1c I think, slightly wavy when freshly washed, and then it slowly straightens out more until my next wash. Idk how that works. Anyways, I always find that my hair overall looks best right before washing it, like it looks like its blown out buttt my scalp feels greasy enough that I want to clean it😭 does anyone else go through something similar? How do you deal with it.
