Hi ,I have a dryness on my scalp,sort of an exema.Up until last year I have never had any skin problems,but last fall I had a very itchy back accompanied by a rash. My dermatologist called it a nerve condition and gave me medication to treat it.,It has improved greatly but I have something like it on my scalp ,only in a few areas and it doesn t want to get better and I don t like using steroids.Please help,it is dry and itchy.Thank you!
