Skin and hair care products that contain chemicals will also cause eczema. Many of these products contain synthetic fragrances that are very unhealthy for your skin, especially if you have a skin condition. If you are an eczema sufferer make it a conscious effort to avoid these types of products. Household cleaners can also be a concern and I know they have to be used to keep a nice, tidy, clean house. As you are cleaning be sure to use gloves and clothing that will cover and protect your skin.
