Use liquid laundry detergent that is unscented and mild. Rinse clothing and bedding thoroughly after washing to remove detergent residue. Avoid chemicals and extreme heat or cold, which can worsen the condition. Use cosmetics lightly and seldom. Avoid products with perfume and dyes, and ingredients such as urea, lactic acid or other alphahydroxy acids.
Topical steroids are key medications for controlling the itching and inflammation.
Used immediately after bathing, they also help keep the skin hydrated. Most steroids require a prescription. They cause flare-ups when the medications are discontinued. Antihistamines may help relieve itching, often sedating the patient. They are most useful when given at bedtime.
