Cradle cap

I’m losing it. I need this gone and I already do what her pediatrician recommended. Oil, soft brush/comb the flakes, wash it out. Man it keeps coming right back! She lost almost all her hair from this and she used to have a head full. What can I do I tried baby oil, coconut oil, aquaphor. Even baby aveeno cream on it. How do I keep it away and is there a way to help her hair grow back faster? I’m so sad. These photos aren’t in order or anything.
