Someone please help?

I seriously do not know what to do with my child’s hair .

I’m half Mexican an white, so I have American hair? I guess that’s how to explain I don’t know lol..,, sorry.

Anyways, my son is mixed with white, Mexican and black. So his hair is curly but when it’s long it’s loose curls. But I ‘feel’ like I have to wash it every day for it to look healthy.

When it drys, it looks dry. Like I fried his hair. 🤦🏻‍♀️

Even tho I do not wash it every day, it’s the same result... looks dry by the time the day is over with.

It’s like his hair has no oils... what do I do?
