WHAT IS DANDRUFF?
A skin condition characterized by dry or greasy, white scales. Dandruff is a form of seborrheic dermatitis and is not contagious.
It normally affects scalp, eyebrows, forehead, face, and folds around the nose, behind ears, external ear canal or skin of the trunk, especially over the upper back.
SIGNS & SYMPTOMS
Flaking, white scales over reddish patches on the skin. Scales adhere to hair shafts. There may be itching, but they are usually painless unless complicated by infection.
Just as we have sweat glands, we also have sebaceous glands that secrete sebum. Sebum along with sweat and environmental material constitute the oil on the surface of skin. In some individuals there is excess secretion of sebum, which dries and irritates the skin. Hence care of dandruff is virtually life long.

HOW TO PREVENT
Cannot be prevented. To minimize severity or frequency of flare-ups:
This is a chronic condition, but it is often characterized by long periods of inactivity. During active phases, symptoms can be controlled with treatment.
Shampoo vigorously and as often as once a day. The shampoo you use is not as important as the way you scrub your scalp. Loosen scales with your fingernails while shampooing, and scrub at least 5 minutes.
No restrictions. Outdoor activities in summer may help.
No special diet.
