I went through a bad patch last year and got some pretty bad dandruff. I don't usually get this so it was a bit of a shock. I had heard and seen a lot about head and shoulders so it was the first and only product I went and purchased.
First off I really like the smell. It is fresh and clean and really lingers in my hair. This really did an excellent job at getting rid of my dandruff but I felt like I needed to use it daily to get rid of it and I really hate washing my hair everyday. In fact I now wash it 1-2 times a week.
Thankfully my dandruff was short lived and went away after about a month so I returned to my normal shampoo and conditioner. This certainly did what it was supposed to while I was using it. Thanks goodness the dandruff never came back as I have black hair and it was so horrible and unsightly. Give this a try and see if it will help you!
