Curly girls I need ur help plz

Im so close to shelling out money so i can get my hair washed at a salon or beauty school once a week BECAUSE I DONT KNOW HOW TO TAKE CARE OF MY HAIR and i don’t think im doing it right

Idk my curl pattern when I had super long hair to my hips it was wavy ish
then I cut it and it got curly and I cut it again above my shoulders recently a lil too short and it became even more curly and I’m at wits end I have no idea how to style it or take care of it practically
maintainance looks like alot and overwhelming ik curls need moisture but I live in a very dry climate so I’ve been straightening the hell out of it but I need to stop damaging my hair

idk how to make not look like a thick frizzy mess I Lwooey want finger coil my hair
Am crying-
