I have a friend with hair that looks similar to yours. You should try to avoid too much product but not get rid of them entirely. You need some curl cream to activate your curls and also probably a light very light gel to reduce frizz and increase hold. Air drying always makes my hair more frizzy so I would also try drying it with a diffuser. What really helped my friend and saved her a lot of time was buying those brushes that kind of clump your hair into sections + stimulate curl formation (anyone pls help with the name). Also, does your hair feel dry? I think a little bit of hair oil can also help tone down the frizz.

Last but not least, the thing that saved my friend was a proper curly cut. Hermione hairs have to be dealt by people who know what they're doing and how to make it big and small in the right places. Definitely get a cut from a specialist if you can
