How common is dandruff as a true condition?

Question

I suspect that most of the time people just have some residue from hair gels or conditioners that shows up as white flakes and that its advertising that makes people think they need to use dandruff treatment shampoos? Am I wrong and lots of folks really do need this stuff?

Answer 1

Changing shampoos can help. I switched to one from the health food store.......no more oily scalp and less hair loss as well.
