Dandruff is a skin condition that mainly affects the scalp marked by the white flakes on the scalp. Almost all of us have suffered from dandruff at some point in our lives. It isn't about your hair, or how often you wash it. Instead, it's about the skin on your scalp. It could be due to the dryness of the scalp or excessive production of oil on the scalp.

Dandruff is harmless but it can be embarrassing and itchy and difficult to get rid of. The exact causes for dandruff are unclear but believed to involve a number of genetic and environmental factors. The condition can be made worse by not washing your hair regularly. It may worsen during winters. Dandruff can also appear due to very dry skin, dermatitis, eczema, bacterial infection, fungal infections and oily skin. A more severe form of the condition, which includes inflammation of the skin, is known as seborrheic dermatitis.

There are some OTC treatments that can help you clear off your dandruff. There are some shampoos available over the counter for treating mild dandruff. The best way to avoid dandruff is to keep your hair and scalp as clean as possible. Use a gentle shampoo to reduce the oiliness of your skin. Follow a healthy diet. Severe cases may require clinical assessment of scalp and treatment.
