Dandruff
"I used Nizoral for about 8 years.  It was excellent for eliminating dandruff which was a bad problem.  But about one year ago I started having severe itching on my upper back and upper front (chest) area.  It was complete itching so severe that benadryl ointment (over the counter) for poison ivy relief and similar products were needed to calm the itchiness.  Crazy itchiness!  My dermatologist gave me steroid creams for the itching and I requested a biopsy to find out more.  Inflammation showed.  I decided to quit using Nizoral and finally the itching went away mostly.  I use baby shampoo now followed by Head and Shoulders shampoo.  So far so good.  Be warned that you might develop an allergy to Nizoral or the generic years later."
