The Correct Option is D
Solution and Explanation
The skin reaction after using a hair dye is typically an allergic contact dermatitis. This condition is commonly caused by an ingredient known as p-Phenylenediamine (PPD). PPD is frequently used in hair dyes to achieve permanent color. It is recognized as a potent allergen that can lead to skin reactions when applied to some individuals.
When an allergy occurs, the body's immune system overreacts to this chemical, resulting in symptoms like redness, itching, and swelling in the affected area. To confirm the responsible allergen, a patch test can be carried out, which might show sensitivity specifically to PPD.
In this context, the other options such as Pollen, Chromates, and Balsam of Peru are unrelated to hair dye allergies. Pollen is an environmental allergen, Chromates are often related to leather or cement allergies, and Balsam of Peru is a fragrance component that may cause reactions but is not typically related to hair dye use.
Therefore, the chemical responsible for the skin reaction in this case is p-Phenylenediamine.
