Depends: It greatly depends on what the cause of the dermatitis is; if is contact dermatitis, you may make do with oatmeal baths and calamine lotion. Other variants will require their own specific therapies.

Protect: Avoid things that make you break out, soaps & wetness. Wash your hands only when necessary. Wear gloves when needed. Wear clothes made of cotton. Bathe only with a small amount of mild unscented soap, such as dove. Keep the water temperature cool or warm, not hot. Use the medicine your doctor gave you. Use a plain moisturizer daily. Avoid scratching or rubbing the itchy area. Manage stress.
