It sounds as if your son does not have the typical allergic eczema seen in many babies, but his skin condition is called seborrhoeic eczema. This type of eczema usually clears up by itself at about 6 months. Typically babies with seborrhoeic eczema have an itchy scalp as you mention here. Changing your baby's diet will not make any difference to the rash while it is present. The treatment is to use a mild baby shampoo such as Elizabeth Anne's baby shampoo every second day. If the rash is troublesome you can occasionally use a very mild cortisone ointment such as Mylocort, but only if and when necessary.Advantan should definitely not be used at all. Do not apply a zinc cream to his scalp.
