Dandruff Treatment


Dandruff is a common chronic scalp condition marked by flaking of the skin on your scalp. Dandruff isn't contagious or serious. But 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.


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.


Causes

Dandruff can have several causes, including:


  • 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 (sternum), 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.
  • A yeastlike fungus (Malassezia). Malassezia lives on the scalps of most adults. But, for some, it irritates the scalp and can 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.

  • Dry skin. Flakes from dry skin are generally smaller and less oily than those from other causes of dandruff. And, redness or inflammation is unlikely. You'll probably have dry skin on other parts of the body, such as your legs and arms, too.
  • Sensitivity to hair care products (contact dermatitis). Sometimes sensitivities to certain ingredients in hair care products or hair dyes can cause a red, itchy, scaly scalp.
