Seborrheic Dermatitis

A common rash of the head/neck and chest, seborrheic dermatitis is an inflammatory condition that targets oil-producing areas. Scalp dandruff or seborrhea is probably the most recognizable feature. Another well-known variant would be “cradle cap” of newborns and infants.  

Causes

The cause of seborrheic dermatitis is not completely clear, but it is suspected to involve an inflammatory reaction to a yeast naturally present on the skin. The yeast is believed to feed off our body’s natural oils, which explains the areas of involvement and other corresponding features. For instance, symptoms may come and go, and may be worse during particular seasons (eg, during cold weather); flares can also occur during periods of stress, hormonal changes, or illness; finally, severe involvement can be seen in those with certain neurologic conditions, such as Parkinson’s – all of these features can be explained by fluctuations or changes in oil-gland activity. 

It should be noted that seborrheic dermatitis is NOT related to diet and is NOT considered contagious (though it does commonly run in families).  Symptoms may appear at any age, either gradually or suddenly, and may last for many years or even disappear by itself. Often, symptoms may periodically worsen or improve without any apparent reason.

Treatment

This skin condition is considered treatable but not curable. With proper treatment, one can expect considerable improvement or even temporary resolution. Treatment strategies involve removal of your skin’s yeast and reducing its inflammatory response. Speak with your dermatologist about the numerous available options to determine the ideal treatment plan for you.
