First, what on earth is cradle cap anyway? Cradle cap is thick yellow or white crusty or oily patches on baby’s scalp. Doctors can prescribe a medicated shampoo or ointment depending on the case, however, most cases go away on their own in a few months. I have been battling this fight since my daughter was two months old. I would use one product, it would clear up for a few days and come right back. It was exhausting, not to mention expensive. I eventually found the best cradle cap shampoo that actually work.
