Full Answer

Seborrheic dermatitis is seasonal and occurs as a result of yeast or fungus found in the oil secretion of the skin, explains Mayo Clinic. People with HIV, Parkinson's disease and congestive heart failure are more likely to develop seborrheic dermatitis.

Direct contact with allergens or irritants may result in contact dermatitis. Allergens that cause this condition include preservatives found in lotions and creams, cosmetics, perfumes and nickel-made jewelry. Exposure of the skin to certain cleaning products or toxic plants such as poison ivy may cause the problem.

A problem with the immune system, certain genetic factors and bacteria can lead to eczema, a condition that is common with infants, explains Mayo Clinic. The problem may occur due to dry skin and environmental factors. Risk factors for atopic dermatitis include asthma, allergies and hay fever. People with a family history of eczema can easily suffer from the disease.

Certain occupations may trigger dermatitis, including health care workers who are usually at a risk of contracting eczema, states Mayo Clinic. Workers in organizations that require direct contact with solvents or metals are likely to suffer from contact dermatitis.
