So my ds has some flaky cadle cap, but he also has a ton of hair, like a grown man's headful. I tried putting olive oil all over his head last night, let it sit a little while, then gave him a bath. This morning it looks like the cradle cap is still there, at least somewhat, and of course his hair is all greasy. Did I do this wrong? Or do I need to do it a few times? Is there a way to deal with getting the olive oil to his scalp past his hair that I'm not thinking of?
