Symptoms: Often affects the face, scalp and chest. Other areas of the body affected including skin folds such as the arpits, groin are and in and around the ears.
Causes: It may be caused by a yeast (fungus) contained in the oil produced by the skin. Seborrheic dermatitis is not contagious, nor is there a link with diet but it can get worse due to illness, stress, tiredness, change of season or deterioration of health. It affects around 1-3% of the adult population and is believed that men are more likely to be affected than women.
