recs needed

in short my hair is the most inconsistent thing in my life. i have identified 3 different textures on my head. i get curly, wavy, and whatever the last picture is. i’ve been on this journey of figuring out my hair off and on for years because this keeps driving me to quit and i don’t know what to do other than constant heat styling at this point. if i leave it completely alone if gets puffy, frizzy, and makes me feel like a poodle but i get a few very curly pieces when i was a kid i had beautiful curly hair and there’s been a few points in time where ive been able to get almost back there. i’ve tried CGM, using minimal but moisturizing products, many many products, air drying, diffusing, oils, did a protein mask once, didn’t use heat for years, and now here we are and im stuck. please help me
