How to keep my hair dry during swimming?

I have black and curly hair. I swim daily, and have to shampoo and condition my hair every day! Could you suggest me how to keep my hair dry and avoid washing them daily? I’ve tried swimming caps but they dont keep my hair dry.Leave-in conditioner also gets washed away in water. I am looking for something which acts like a protective mask during swimming, and does not look sticky or ugly during the rest of the day.
