Full Answer

This condition is not contagious or life-threatening but it can make the patient feel uncomfortable and self-conscious. When the dermatitis is the result of an allergy, the immune system plays a central role. In this case, when an object touches the skin, the immune system mistakenly assumes that it is under an attack. It responds by releasing the antibodies to counteract the invader. A series of events take place that leads to the production of chemicals such as histamine. This is what causes the allergic contact dermatitis which shows on the skin as itchy rashes.

However, the first time the skin touches an allergic object, it is not affected, but the skin gets sensitized. This leads to an allergic reaction the second time contact occurs. There are several triggers to dermatitis, some of which include nickel metal normally found in belt buckles and jewelry, some skin medications, latex, rubber, hair straighteners and dyes, fragrances in perfumes, soaps, shampoos, cosmetics and lotions, citrus fruits and poison sumac.
