how should i approach my curl routine as someone who’s hair gets greasy within a day?

Hello! Basically the title. I have very long, low porosity wavy-curly hair. as of lately, I have been trying out different products and routines and styling methods in order to embrace my natural hair pattern. The only issue is my hair gets greasy within 24 hours of washing it. I have tried ‘training’ it in the past, but ultimately 24h or sliiiightly longer is my maximum. I am able to preserve it for one more day (so max 2 days between washes) by using dry shampoo, but any longer than that, and my scalp is extremely itchy and uncomfortable. I’ve also been advised by my hairdresser that dry shampoo is actually kind of bad for your scalp/hair? So.. should I do a full wash and curl routine daily? Thank you!
