For mild, regular itching in both ears, the most common causes are dry skin or mild inflammation. I recommend starting with a few drops of olive oil or mineral oil to moisturize the ear canal if it is just dry. If there is mild inflammation, over-the-counter hydrocortisone (1%) ear drops can help relieve the itch. However, please do not insert cotton swabs or sharp objects, as this worsens itching. Most importantly, consult a doctor to examine your ears before using any drops, to ensure your eardrums are intact and there is no underlying infection. This is a very common, easily treatable issue, so there is no need to worry.
