SERIOUSLY NEED HAIR HELPPPP!!!!!!!!!

okay girls I have straight long hair and whenever I curl my hair IT DOESNT LAST !!! The curls last at most 30 minutes AT MOST😔 I love how curly hair looks on me and I have no idea how to make them last longer :( I’ve tried the kenra hair spray and it didn’t really work. Pleaseeeeee 🥺 what makes your curls last all day?!
