Dandruff is a common chronic scalp condition marked by itching and flaking of the skin on your scalp. Although dandruff isn’t contagious and is rarely serious, 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.
Most cases of dandruff don’t require a doctor’s care. But if you’re still scratching your head after several weeks of experimenting with over-the-counter dandruff shampoos, or if your scalp becomes red or swollen, see your doctor or dermatologist. Often dandruff can be diagnosed simply by looking at your hair and scalp.
