A number of health conditions, allergies, genetic factors and irritants can cause different types of dermatitis:

  • Atopic dermatitis (eczema). This condition often occurs with allergies and frequently occurs in families in which members have asthma, hay fever or eczema.
  • Contact dermatitis. This condition results from direct contact with one of many irritants or allergens — such as poison ivy; jewelry containing nickel; and certain cleaning products, perfumes and cosmetics.
  • Seborrheic dermatitis. This condition is common in people with oily skin or hair, and it may come and go depending on the season. It's likely that hereditary factors play a role in this condition.
