Contact dermatitis is a common allergic reaction associated with hair coloring. This condition occurs when the skin becomes inflamed due to exposure to irritants or allergens in hair dye products. Hair coloring agents often contain substances like ammonia, peroxide, and various chemicals that can trigger a reaction in sensitive individuals.

In cases of contact dermatitis, individuals might experience symptoms such as redness, swelling, itching, and rash in the area where the dye has come into contact with the skin. Recognizing this reaction is crucial for cosmetologists, as it helps them to implement appropriate safety measures, such as performing patch tests before applying hair color to clients.

While itching, redness around the eyes, and nausea can be associated with hair coloring, they are not the primary allergic reactions. For example, while itching may occur due to various reasons, including skin sensitivity, it does not specifically denote an allergic reaction. Redness around the eyes can suggest sensitivity but is not exclusive to allergic responses related to hair dye. Nausea is not a typical reaction to hair coloring and may suggest a different underlying issue unrelated to the chemical composition of the hair dye itself.
