Contact Dermatitis
Contact dermatitis is another common type of skin rashes which results due to the direct contact or an allergic reaction to some substances. Contact dermatitis due to an irritant typically produces a scaly, dry, and non-itchy rash all over the body or on the areas of allergen contact. A number of substances such as industrial chemicals or chemical products that you might come into contact with can cause contact dermatitis. Some common contact dermatitis allergens are poison ivy, latex rubber, and nickel.
