Mixed babies

So my daughter has a combination of my hair and her fathers. Her hair is more like mine but she has his curls. I just don’t know what to use in her hair to keep them nice and bouncy, I’ve tried so many things. My hair has always been really thick and wavy so I never paid much mind to care for it ( regretting it soooooo much now) whatever I put in her hair it just absorbs and doesn’t give it like let a shine just fluffs back out.
