Im having itchy outer ears. dry flakes skin is build up in my outer ear and on my tragus. what could this be? what can l do to help it? do i see an ear doctor or dermatologist?

First try OTC hydrocortisone cream over the areas for a week or so if it does not get better see a dermatologist.

It appears you have Seborrheic Dermatitis, a more active form of dandruff, not uncommon to develop in the external ear canals. It requires 3 x weekly application with a Q-tip and a steroid cream, not ointment. Apply in the ear canal at night and gently clean out with a moistened Q-tip in the morning.
