Hi Steve,
My 5-year-old daughter has lamellar ichthyosis and she has very dry ears. Every night, I add a couple of drops of vitamin E to warm olive oil and then massage it over and around her ears, the skin pratically "drinks" it up and the next day there is always less dryness. I also have to put olive oil into her ears (without the vitamin E) or use a product like Waxsol as the dry skin falls in and mixes with the wax. Once that hardens, she ends up having a hearing problem.
Anyway, try the olive oil treatment every night before bed and in the morning after bathing and see how you get on.
Any probs, let me know.
Good luck!
