What are the risk factors for dermatitis?

Factors that increase your chances of getting dermatitis include:

  • age
  • the environment
  • a family history of dermatitis
  • health conditions
  • allergies
  • asthma

Some factors increase your risk for certain types of dermatitis more than others. For example, frequent washing and drying of hands will strip your skin’s protective oils and change its pH balance. Healthcare workers typically have hand dermatitis due to this.
