Dandruff is a common condition that is not contagious or dangerous. Although it's embarrassing and can be itchy, it won't hurt you or anyone else. In most cases dandruff can be controlled with over-the-counter dandruff shampoo, but if that isn't working, see your doctor to rule out an underlying cause.
The symptoms in teenagers and adults are white flaky pieces of dead skin that fall off of the scalp onto hair and shoulders. Some people notice more dandruff in the fall and winter months when the indoor air is dryer due to heating. Infants can get cradle cap, which is a type of dandruff normally found in newborns but can appear anytime during infancy. Cradle cap is not dangerous and usually clears up on its own. Your pediatrician can advise you whether or not special care is needed.

This is sensitivity to hair care products such as shampoo or dyes.
When dry skin is the cause, the flakes are smaller and less oily than other causes and redness or inflammation is unlikely.
Malassezia is a yeast-like fungus that lives on the scalp of most adults but is irritating to some people, causing dandruff.
