Tips/ideas to prevent sweating out hairstyles?

A • P.L.U.R✌️❤️
So my head gets like really hot, even when my body isnt necessarily hot. And my scalp sweats so much it alway always always ruins my hair. I can never style it or make it cute or whatever because theres no point when im gonna sweat it out anyway. My hair is curly/wavy and i just wanna know if there are tips for reducing the sweat, or any ideas even? Or like ways to set the hair or something? My guy wants to take me out and get all dressed up and go walking around downtown and i really wanna look a little fancy lol.
