The presence of redness, swelling, or itching of the skin is a common indication of an allergic reaction to a product used in a salon. When someone is allergic to a substance, the immune system reacts to that product as if it were a harmful invader. This reaction often leads to localized skin responses, including inflammation characterized by redness and swelling. Additionally, itching is a typical symptom as histamines are released in response to the allergen. Recognizing these signs is crucial for salon professionals to ensure client safety and to prevent further complications.

Other symptoms listed, such as dizziness or nausea, can be caused by various factors and are not necessarily specific to allergic reactions related to salon products. Dry hair, on the other hand, is more associated with product damage or lack of moisture rather than a direct allergic response. Being able to identify specific allergy symptoms allows cosmetologists to respond appropriately and recommend alternative products or treatments.
