I need help! My gelding developed a sunburn about 3 months back. I have been putting Aloe Gel and Desatin on it at least every other day, with no luck! It has spread completely around his blue eye and down his white muzzle. He is basically missing all the hair on the left side of his face (which by the way is completely white) I am so unsure what to do! It looks absolutely terrible and I feel like a terrible horse owner. I have never had an issue like this before so I am not sure how to tackle it! Please any sort of advice would be greatful!
