Best products for wavy hair

Bella

I just discovered that my hair is not actually straight if I take care of it 😂 I wanna keep it this way so does anyone have any products that help take care of wavy/curly hair? It’s currently a mix of curly at the front and it gets more wavy toward the back. I’m a complete beginner so any products that are easy to get a hold of and use would be appreciated :)
