I have no idea how to take care of my hair

Omgee ts is low-key so embarrassing to admit so idk why I’m spilling the beans when no one's forcing me lol 🥹. So basically I just have no idea how to take care of my hair. Like I think it’s type 2a but sometimes it’s just wavier or just straight up straight. And like I try to put in products to make it look more defined and I scrunch my hair and do all the wavy hair hacks I see online but it just doesn’t work 😔. My hair somehow comes out less wavy than what I started with. Like wtf man I want to have wavy hair. I’m not forcing curls/waves either, when I come out of the shower it curls. So idk what I’m doing wrong ☹️.
