What causes eczema?

Causes of eczema. Often the cause of the eczema is unknown, or there may be a number of different factors all working together. Eczema often runs in families, but it is not spread from one person to another.


Chemicals, detergents, soap or shampoo can all irritate the skin. Some substances may not be irritants but if the skin becomes sensitised – or allergic – to them they may cause a reaction.
