If the vulva itching is caused by allergic reasons, such as allergy to condoms or allergy to the clothing used, toilet paper, etc., in this case, the first thing to do is to remove the allergen, after removing the allergen, you can choose to use potassium permanganate fumigation or directly use dermatoprost, dexamethasone ointment and other hormonal drugs for external application.
