The Itching is usually due to a disturbance in the skin of the external auditory canal. Ear canal skin is very sensitive. The slightest accumulation of debris, even a dead hair, may be felt as an itching sensation. Often, dryness in the ear is what causes inner ear itching.
Ear itching could be an allergic reaction to any of the following: Certain foods. Cosmetics, dyes or detergents. Industrial chemicals, such as those found in elastic, latex or rubber. Metals such as those used in jewelry. Poison ivy or oak. Stings or bites.
