Dandruff is a common chronic scalp condition marked by 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.
Causes
Dandruff can have several causes, including:
· Dry skin. Simple dry skin is the most common cause of dandruff. Flakes from dry skin are generally smaller and less oily than those from other causes of dandruff, and you'll likely have symptoms and signs of dry skin on other parts of the body, such as your legs and arms.
· Irritated, oily skin (seborrheic dermatitis). This condition, one of the most frequent causes of dandruff, is marked by red, greasy skin covered with flaky white or yellow scales. Seborrheic dermatitis may affect your scalp and other areas rich in oil glands, such as your eyebrows, the sides of your nose and the backs of your ears, your breastbone, your groin area, and sometimes your armpits.
· Not shampooing often enough. If you don't regularly wash your hair, oils and skin cells from your scalp can build up, causing dandruff.
· Other skin conditions. People with skin conditions such as eczema — a chronic, inflammatory skin condition — or psoriasis — a skin condition marked by a rapid buildup of rough, dry, dead skin cells that form thick scales — may appear to have dandruff.
· A yeast-like fungus (malassezia). Malassezia lives on the scalps of most adults, but for some, it irritates the scalp. This can irritate your scalp and cause more skin cells to grow. The extra skin cells die and fall off, making them appear white and flaky in your hair or on your clothes. Why malassezia irritates some scalps isn't known.
· Sensitivity to hair care products (contact dermatitis).Sometimes sensitivities to certain ingredients in hair care products or hair dyes, especially paraphenylenediamine, can cause a red, itchy, scaly scalp. Shampooing too often or using too many styling products also may irritate your scalp, causing dandruff.
Symptoms
For most teens and adults, dandruff symptoms are easy to spot: white, oily looking flakes of dead skin that dot your hair and shoulders, and a possibly itchy, scaly scalp. The condition may worsen during the fall and winter, when indoor heating can contribute to dry skin, and improve during the summer.
A type of dandruff called cradle cap can affect babies. This disorder, which causes a scaly, crusty scalp, is most common in newborns, but it can occur anytime during infancy. Although it can be alarming for parents, cradle cap isn't dangerous and usually clears up on its own by the time a baby is 3 years old.
Risk factors
Almost anyone can have dandruff, but certain factors can make you more susceptible:
· Age. Dandruff usually begins in young adulthood and continues through middle age. That doesn't mean older adults don't get dandruff. For some people, the problem can be lifelong.
· Being male. Because more men have dandruff, some researchers think male hormones may play a role. Men also have larger oil-producing glands on their scalps, which can contribute to dandruff.
· Oily hair and scalp. Malassezia feeds on oils in your scalp. For that reason, having excessively oily skin and hair makes you more prone to dandruff.
· Poor diet. If your diet lacks foods high in zinc, B vitamins or certain types of fats, you may be more likely to have dandruff.
· Certain illnesses. For reasons that aren't clear, adults with neurological diseases, such as Parkinson's disease, are more likely to develop seborrheic dermatitis and dandruff. So are people with HIV infection and those recovering from stressful conditions, particularly heart attack and stroke, and those with compromised immune systems.

Medical advice
In addition to regular shampooing, you can take steps to reduce your risk of developing dandruff:
· Learn to manage stress. Stress affects your overall health, making you susceptible to a number of conditions and diseases. It can even help trigger dandruff or worsen existing symptoms.
· Shampoo often. If you tend to have an oily scalp, daily shampooing may help prevent dandruff.
· Cut back on styling products. Hair sprays, styling gels, mousses and hair waxes can all build up on your hair and scalp, making them oilier.
· Eat a healthy diet. A diet that provides enough zinc, B vitamins and certain types of fats may help prevent dandruff.
· Get a little sun. Sunlight may be good for dandruff. But because exposure to ultraviolet light damages your skin and increases your risk of skin cancer, don't sunbathe. Instead, just spend a little time outdoors. And be sure to wear sunscreen on your face and body.
