Itching and redness are hallmark symptoms of dermatitis, particularly when it is triggered by chemical exposure. Dermatitis refers to inflammation of the skin and can manifest in various ways, with itching being a common response as the skin becomes irritated. Redness is also a key sign of inflammation, indicating that the area has increased blood flow in response to the irritants.

When chemicals come into contact with the skin, they can disrupt its protective barrier, leading to inflammation and the body’s immune response, which typically results in these symptoms. Other options describe symptoms that are not typically associated with chemical dermatitis. For example, swelling and bruising might indicate a traumatic injury rather than a chemical reaction, while dryness and flaking are more characteristic of chronic skin conditions or different types of dermatitis, and change in hair color is not relevant to dermatitis at all. Understanding these symptoms helps in identifying and treating dermatitis effectively.
