Dandruff is a common chronic scalp condition marked by flaking of the skin on your scalp. Dandruff isn't contagious or serious. But it can be embarrassing and sometimes difficult to treat.

The good news is that dandruff usually can be controlled. Mild cases of dandruff may need nothing more than daily shampooing with a gentle cleanser. More-stubborn cases of dandruff often respond to medicated shampoos.
