Detailed answer

Dry skin can be a result of allergies due to several factors. Allergic reactions can cause inflammation and damage to the skin's protective barrier, leading to moisture loss. Certain allergens, such as pollen or pet dander, can trigger an immune response in the skin, resulting in dryness and itching. Additionally, some allergy medications can have drying side effects on the skin. If you suspect your dry skin is caused by allergies, it is best to consult with a dermatologist to identify the specific allergens and develop an appropriate treatment plan.
