What is the technical term for an allergy caused by hair tint?

Atopic Dermatitis
Contact Dermatitis
Dermatitis Venenata
Eczema

The correct answer is: Dermatitis Venenata

The term "Dermatitis Venenata" specifically refers to a type of dermatitis that results from exposure to a chemical irritant or allergen, which aligns with the context of an allergy caused by hair tint. Hair tints often contain various chemical compounds that can trigger a reaction in susceptible individuals when they come into contact with the skin. This reaction can manifest as redness, itching, or inflammation in the area affected. While other terms like "Atopic Dermatitis" and "Eczema" refer to chronic inflammatory skin conditions often associated with genetic and environmental factors, they do not specifically denote allergic responses to chemical substances. "Contact Dermatitis," while closely related, generally encompasses both allergic and irritant reactions, making it a broader category. Dermatitis Venenata is more precise for describing the reaction specifically linked to chemical exposure, such as that from hair dye.
