What do you suggest if my child is 2month old and she has dandruff.what do i put on it?

This is cradle cap : cradle cap or seborrheic dermatitis is a very common condition in young babies. The scalp becomes full of flaky skin that can come off on its own, appearing as dandruff. In the worst cases, the skin can become thick and plaque like. I find the natural use of olive oil or mayonnaise over night followed by scraping it out with a baby comb is most effective. I hope this helps.
