There are many types of allergies, ranging from the most common, such as hay fever and food allergies, to the least common. Allergies can be caused by a wide variety of substances, from pet dander to pollen and dust. Some allergies may be more or less common than others, and it can be difficult to determine which allergies are the least popular.
