What can I do with my hair?

I Have Thick Brown Curly Hair &+ It Normally Gose Friizyy After A While Esspecialy in the winter tbh I dont know what to do with it, like have it in diffrent styles I want.. but I dont know really’ I normally straighteen it and have it down but it gets boring after a while &+ I hate having my hair up at school,1 reason because the one I love hate girls who have theri hair up but I dint like it before anyway’ I sometimes have my hair up at home &+ outings , but I want difrent styles at school .. I sometimes put my headband on but iit always flops over the top after a while because my hairs thick &+ its more of a skinny headband buuh I dont like the big ones. some times I use other headbands like the elastic ones’ but they make your head go itchy after a while, I sometimes put my frindge up buut its out of style know tbh, :L I would have my hair curly ( natural ) but it always go propa frizzy after a while

any idea..?
