My son has had dandruff on his head since the day he was born. When I used ketoconazole shampoo, it temporarily cleared up. But now it has doubled in size. What is the solution?

A. Hello! It can be some kind of allergic reaction on the skin and maybe in the past your child had cradle cap issues. Consult your child doctor for a personal evaluation and seek assistance in this matter. Maintain a good personal hygiene routine for your child and follow your doctors advice.
