Nickel allergy is one of the most common causes of allergic contact dermatitis — an itchy rash that appears when your skin touches a normally harmless substance.

Nickel allergy is commonly associated with earrings and jewelry for other body piercings. But nickel can be found in many everyday items — from coins to necklace clasps, from watchbands to eyeglass frames.

Nickel allergy can affect people of all ages. You may develop nickel allergy after a single exposure to nickel or after repeated or prolonged exposure. Treatments can reduce the symptoms of nickel allergy. Once you develop nickel allergy, however, you will always be sensitive to the metal and should avoid contact.
