If you have dandruff, do not worry about being alone with your problem. With one out of every two people in the entire world having, or having had, that same problem as yours, you are definitely not alone with it. Dandruff is a common hair problem. Embarrassing indeed, but a very, very common problem nonetheless.
What causes dandruff? Well, you see, our entire skin, from our scalps to the soles of our feet, sheds dead skin cells on a daily basis. We get a complete coating of new skin every 28 days or so, but we hardly even notice it.
