Symptoms
-
Symptoms of dandruff include white, oily flakes and dead skin in your hair and on your shoulders. Dandruff also makes the scalp dry and itchy.
Causes
-
Dry, irritated or oily skin can cause dandruff. If you have psoriasis or eczema, you can also develop this scalp condition. Experts say not shampooing enough or using too many styling products can also be a factor.

Risk Factors
-
While almost anyone can have dandruff, people with oily hair or scalps are more susceptible. According to the Mayo Clinic, it often begins in young adulthood and continues until middle age. They say men are more likely to have dandruff because they have larger producing oil glands. Poor diet and certain illnesses, like Parkinson's, can also place someone at a higher risk for dandruff.
Treatment
-
There are several over-the-counter dandruff shampoos. Experts say they are not all the same, so you may have to try several out before finding one that works for you.
When to See a Doctor
-
While most cases of dandruff do not require a doctor's care, if your scalp continues to itch for several weeks after trying over-the-counter medications or if it becomes red or swollen, consult your physician.
