HELP anti-frizz

I’m a sophomore (10 grade) and all my life I’ve had frizzy hair. For a teen going through puberty, I’d say I’m pretty confident with how I look. I love my body, and there are some thing I don’t like about my face but I think I look pretty. there’s just one thing- my hair. I hate it so much, I’ve honestly thought of just shaving it all off. It’s SOOO FRIZZY. I straighten it, and it gets better, but then it’s just straight frizzy instead of curly frizzy. I always have so much frizzy at the top and side of my head. It’s not just me being self-conscious either, my friends have commented about it (not in a mean way). They’ve tried to help me but nothing works. it’s not something I can just hide, or put makeup over. I hate it so much, and it’s always there. I can never forget about it, because I feel it itching the back of my neck and waving in front of my face. if I could change one thing about myself, it would be the frizziness of my hair. I’ve tried hairspray, and the only way to keep it all down is if I spray so much that my hair basically becomes a hard shell. somebody please help!! High school is hard enough without hating the thing that people notice most about you. Any anti frizz products, or anything??? I’m desperate.

Here’s a picture of my hair STRAIGHTENED!! and yes, I have a good straightener, it works fine, and I know how to straighten hair.
