What causes itchy ears and no ear wax?

Several factors can contribute to itchy ears without the presence of earwax:

1. Dry Ears: A lack of earwax production or very dry earwax can cause itching and flaky skin in the ear canal. This condition, known as dry ear or seborrheic dermatitis of the ear, often occurs due to aging or certain medical conditions.

2. Allergies: Allergies to substances such as pollen, dust mites, pet dander, or even certain cosmetics or hair products can cause allergic reactions that lead to ear itching.

3. Irritants: Exposure to irritants, like harsh soaps, shampoos, or ear cleaners, can cause inflammation and itching in the ear canal. Some chemical ear drops can also be irritating.

4. Skin Conditions: Various skin conditions, such as eczema, psoriasis, or contact dermatitis, can affect the skin inside and around the ears, resulting in itching and discomfort.

5. Ear Infections: In some cases, an underlying ear infection, such as otitis externa (swimmer's ear) or otitis media, can cause itching, especially if there's a perforation of the eardrum.

6. Underlying Medical Conditions: Certain systemic medical conditions, such as diabetes, thyroid disorders, or autoimmune diseases, can lead to skin problems and itching in the ears.

If you're experiencing persistent itchy ears without ear wax, it's advisable to consult a healthcare professional, preferably an otolaryngologist (ear, nose, and throat specialist). They can examine your ear, identify the cause of the itching, and provide appropriate treatment accordingly. Avoiding known irritants and allergens can also help prevent or reduce itchy ears.
