A kitten with bald patches on its nose may have folliculitis. In this case, check if the kitten has other symptoms. You can try applying erythromycin eye ointment. Check the affected area for redness or black spots. If so, clean the area with tea (since it's close to the kitten's mouth and nose, avoid using irritating liquids like alcohol), then apply the erythromycin eye ointment. If this doesn't work, take the kitten to the vet.
