Understanding Dermatitis: Causes, Types, and Treatments

Dermatitis is a common skin condition that can affect people of all ages, causing redness, itching, and irritation. At Dermatology Specialists of Dallas, Dr. Brigitte Sallee, a double board-certified dermatologist and Mohs micrographic surgeon, brings advanced training and extensive experience in treating a wide range of skin concerns, including dermatitis. With her patient-centered approach, treatment plans are designed to address both symptoms and underlying triggers to support healthier skin.

What Causes Dermatitis?

Dermatitis develops when the skin becomes inflamed due to irritants, allergens, or immune system responses. While each case is different, several common causes include:

  • Irritants – Soaps, detergents, or chemicals that strip the skin barrier.

  • Allergens – Substances like fragrances, nickel, or latex that trigger allergic reactions.

  • Genetics – A family history of eczema or other skin conditions can increase risk.

  • Environmental factors – Changes in weather, humidity, or pollutants may exacerbate symptoms.

Understanding the cause is crucial to selecting the most effective treatment strategy.

Types of Dermatitis

There are several types of dermatitis, each with distinct features:

  • Atopic dermatitis – Often called eczema, marked by chronic dryness, itching, and flare-ups.

  • Contact dermatitis – Triggered by exposure to irritants or allergens.

  • Seborrheic dermatitis – Affects oily areas like the scalp, causing dandruff and redness.

  • Nummular dermatitis – Characterized by coin-shaped patches of inflamed skin.

Correct diagnosis ensures patients receive the most effective care.

Treatments for Dermatitis

Dermatologists offer a range of treatments to relieve symptoms and prevent flare-ups. These may include:

  • Topical therapies – Prescription creams or ointments to reduce inflammation and itching.

  • Photodynamic therapy (PDT) – Light-based therapy that may benefit certain chronic cases.

  • Chemical peels and lasers – Helpful for improving skin tone and texture affected by past dermatitis flare-ups.

  • Skincare products – Physician-formulated regimens to strengthen the skin barrier and reduce irritation.

Lifestyle changes, such as using fragrance-free cleansers and maintaining consistent moisturization, are often part of a comprehensive plan.
