Natural product for a wet hair look?

Hello,

I need a hair care product. I have curly hair and would like my hair to look roughly the same as it does after a shower throughout the day, just a bit damper. In particular, I don't want to put excessive chemicals in my hair and thus on my scalp, especially when it comes to estrogenic substances like phthalates and parabens. That's why I don't want to rush to dm or Rossmann and buy the first cheap thing I see.

I've tried using hair oil, but I feel like it wears off pretty quickly. My hair is still soft, but it doesn't look as moisturized.

I've heard about leave-in conditioners. Is that what I need?

Does anyone have any recommendations?

Thanks
