I don't suffer with dandruff that often and when I do, its never a major dandruff outbreak but obviously nobody wants to be seen with dandruff in their hair regardless of how much or little it is.
I tried Head & Shoulders once for dandruff and it did nit work for me, it took a good few washes to get rid of the dandruff firstly and left my hair feeling terribly course.
I am still to give their African Scalp Care range a try, perhaps it would have a different result?!
