tips for wavy hair?

hi all! i'm looking for tips for 2a/b wavy hair. i have really thick hair and it gets oily after like 2 days with no wash. rn im using the loreal volume shampoo and conditioner (i dont think shampoo or conditioner make a lot of difference for me though). aside from that, i use a marc jacobs leave in curl cream and an aussie 2a/b/c curl mousse. i feel like my hair looks constantly wet or slick even after it has fully dried, and it never looks as defined as i want it to. also, i dont like using heat on my hair. i used to dye it a lot so now im trying to put less damagin stuff on it. i would appreciate any tips :)

rundown routine:

shampoo: loreal volume

products after wash: marc jacobs leave in curl cream and aussie mousse. scrunch my hair with my hands but i always leave it to air druy

hair protection: none tbh. i dont have a satin/silk pillow case or a bonnet ;-;
