Dandruff

Dandruff is a common condition that causes the skin on the scalp to flake. It isn't contagious or serious. But it can be embarrassing and difficult to treat.

Mild dandruff can be treated with a gentle daily shampoo. If that doesn't work, a medicated shampoo may help. Symptoms may return later.

Dandruff is considered to be a mild form of seborrheic dermatitis (SB). In babies, seborrheic dermatitis is called cradle cap.

Seborrheic dermatitis and dandruff are part of skin disorders that affects the oil-producing areas of the body.

Both involve itchy, flaking skin. Dandruff is mostly restricted to the scalp, whereas seborrheic dermatitis can also appear on the face, upper chest, armpits, and groin.

Studies show that both conditions are also very common. Up to 42% of infants and 50% of adults may suffer from dandruff or seborrheic dermatitis at one point or another.

Dandruff and seborrheic dermatitis may be caused by many factors, with a nutrient-poor diet being one of them. For instance, low blood levels of zinc, niacin (vitamin B3), riboflavin (vitamin B2), and pyridoxine (vitamin B6) may each play a role. People with dandruff or seborrheic dermatitis may try to consume more of these nutrients.
