Dermatitis is a general term for inflammation of the skin, characterized by redness, itching, and sometimes swelling or blistering. It can result from various causes, including allergic reactions, irritants, infections, or underlying medical conditions. Dermatitis is not a single disease but a group of conditions that affect the skin's appearance and function.

The most common types of dermatitis include atopic dermatitis (eczema), contact dermatitis, seborrheic dermatitis, and nummular dermatitis. Atopic dermatitis often runs in families and tends to appear in people with asthma or hay fever. It typically begins in early childhood and may persist into adulthood. Symptoms include dry, itchy skin that may become scaly or cracked, leading to increased risk of infection.

Contact dermatitis occurs when the skin reacts to a substance it touches, such as certain plants, metals, or chemicals. It can be further divided into allergic contact dermatitis, caused by an allergic reaction to a substance, and irritant contact dermatitis, which results from direct irritation. Common triggers include nickel, fragrances, and preservatives found in cosmetics and household products.

Seborrheic dermatitis is a chronic inflammatory skin condition that commonly affects areas rich in oil glands, such as the scalp, face, and chest. It is characterized by greasy, scaly, and inflamed skin, often accompanied by redness and itching. While the exact cause is unknown, factors such as yeast overgrowth, hormonal changes, and immune system dysfunction may play a role.

Nummular dermatitis, also known as discoid dermatitis, presents as round, coin-shaped patches of inflamed skin. The exact cause is unclear, but it may be linked to dry skin, insect bites, or exposure to harsh soaps and detergents. Symptoms typically include red, scaly patches that can be extremely itchy.

Treatment for dermatitis varies depending on the type and severity but often includes avoiding triggers, using moisturizers, and applying topical corticosteroids or other anti-inflammatory medications. In some cases, oral medications or light therapy may be recommended. Proper skincare and managing underlying conditions can help control symptoms and improve quality of life.
