Missouri Cosmetology Exam Practice 2025 – Complete Study Guide

Redness is a common symptom of a skin allergy due to the body's immune response to allergens. When the skin comes into contact with an irritant or allergen, the immune system can react by increasing blood flow to the affected area, leading to inflammation. This inflammation manifests as redness and often accompanies other symptoms such as itching or swelling. Understanding this response is crucial for cosmetology professionals, as they need to recognize allergic reactions in clients to provide appropriate care and avoid exacerbating the condition.

While dryness, brushing (which may refer to a sensation rather than a direct symptom), and scalp tightness can be related to various skin conditions or reactions, they are less specifically indicative of an allergy compared to redness. Redness is a staple sign of allergic reactions, making it a key symptom to observe in clients who may be experiencing a skin allergy.
