Winter making kitty's ear's dry and itchy, any treatment ideas?

my cat likes to hang out in the backyard a lot, doesn't go far cause she was raised indoors and likes to stay near the house, but we recently moved from a place that doesn't really have a winter season to one that does. just like how my hands get dry and itchy during winter, her ears are suffering too. i've been keeping her inside for the moment but she's getting upset with me. are there any cat-friendly lotions or home remedies i can give her so she can continue enjoying the grand outdoors?

You may need to get a humidifier and keep it between 35-45%. I would use coconut oil. Melt a tiny bit in your hand and put it on the ears. Will take very little to do so...wipe off excess.
