product recommendations for oily scalp and frizzy low porosity hair

hi, i live in a rather humid climate and i also have low porosity and frizzy hair. my hair also tends to fall, and even more if i skip a hair wash day. likewise, my scalp gets oily and my hair gets greasier if i skip a hair wash day. i also have dyed hair (no bleach).

does anyone have any recommendations for drugstore shampoos and/or conditioners that i can use everyday? right now i'm using sunsilk but i don't see any changes or improvements.

any help is appreciated thanks!
