My scalp was so flaky and itchy all over.  This happens every once and I while and I have used all different anti-dandruff shampoos but they never seemed to work all that well and/or had an awful smell.  This time I kept ignoring it hoping it would just go away, tried not to shampoo my hair every day as I've heard that dries out your hair more UNTIL I noticed that it was just getting worse.  I finally broke down and bought Head and Shoulders and I'm soooo glad I did!  After the first application I could no longer see the flakes along my hair line.  I use this shampoo once a week, sometimes...
