Hair type— 2c, 3a. I have low volume, kinda thin and long hair, medium porosity

Hey! I have a wedding coming up, and I am soooo confused if to buy a curl gel or mousse or something else!

I want my curls to stay in place at least for the day since there'll be dancing and the days are gonna be too hectic to keep fixing my hair.

However, I'm skeptical if gel will hold my hair down since I have thin hair. I don't wanna look bald 😭 (no hate to bald people, I'll join the club soon)
