Try a dandriff shampoo. It has the same chemical that is in eczma treatments. Just appply massage well and rinse. Head and Shoulders is a great one to use! The extra lotins and oils can actualy make his eczema worse ! I have had exzema for all my life and have used dandriff shampoo dispite not having dandriff. My scalp still gets a bit itchy in the extreme cold, but it controlls the symptoms nicly. If he continues to have problems a few weeks after you start treatment he might need to be seen by a dermatologist for follow up treatment.
