Broad v specific: An allergy reaction is a very specific sort of immune response involving a specific set of cells and inflammatory mediators. An intolerance has a much broader definition and is typically not an immune system reaction. Lactose intolerance, for instance, is an enzyme deficiency that makes one unable to digest lactose.

They are different : Allergy is an altered response by your immune system to an allergen. Allergens are usually harmless particles like pollens, dust, cat dander or even certain foods, wherein your body has antibodies that fight them releasing chemicals to get rid of them.
Intolerance is where your body is not able to process certain proteins like milk protein or gluten. One good example would be lactose intolerance.
