What are the common causes of a scaly rash?

A rash can be caused by a variety of inflammatory contacts. Called dermatitis, this condition often results in a scaly rash that itches or burns. The problem is usually caused by allergic reactions to various consumer products, insect bites, or caustic plants. Dermatitis can also appear as a result of a number of medical conditions, from eczema, psoriasis, and shingles to lupus, arthritis, and even chickenpox.

A scaly rash can appear on any surface of the skin when the oils naturally produced by the epidermis are not produced. Cold weather is a natural cause of this problem, but only to a lesser degree. On the head, this can lead to excessive dandruff. This condition is officially called dermatitis, but a more specific variety is called seborrheic dermatitis. The latter results in certain areas being broken, such as behind the ears, above the eyes, around the mouth and nose, and on the scalp.

A number of conditions can cause this scaly rash, from allegories to latex or rubber, alcohol-based lotions or shampoos, certain cosmetic products, and clothing dyes. Plants like poison oak or poison ivy are iconic causes of dermatitis. This condition can become even more pronounced with age, emotional stress, oily skin and poor hygiene practices.

Dermatitis is only the first suspect. Eczema, or atopic dermatitis, usually manifests as a red, scaly rash that is often itchy. Psoriasis is another common skin condition that causes a rash on the joints, scalp, and nails. Medications can cause allergic reactions that lead to a rash, as can the sting or sting of various insects.

Some doctors may suspect a viral condition causing a scaly rash, particularly if there are other symptoms. Impetigo is a viral condition of the upper layers of the skin that creates painful red sores. Shingles, chickenpox, measles, rubella, hand/foot/mouth disease, roseola, and scarlet fever can all create a scaly rash due to bacterial infection, especially if the areas are scratched without properly moistening.

According to the National Institutes of Health, some serious conditions can also cause this problem. Rheumatoid arthritis is a condition that can cause occasional skin rashes. The autoimmune disease lupus erythematosus can cause a full-body rash or, in about half of patients, butterfly-shaped patches on the nose and cheeks. A childhood disorder called Kawasaki disease also results in a rash. With these more serious conditions, there are usually other symptoms.
