Itching or rash is a common symptom of allergic reactions to hair color products. This occurs because many hair dyes contain chemicals, such as ammonia and paraphenylenediamine (PPD), that can trigger an immune response in sensitive individuals. The skin may react to these irritants or allergens, resulting in localized reactions, such as redness, swelling, and discomfort. This type of response is particularly frequent among those who may have a predisposition to allergies.

While nausea, headache, and dizziness can occur due to various reasons related to hair treatments, they are not typically associated specifically with allergic reactions to hair color. Nausea may arise from overwhelming odors or chemicals in the treatment environment, headaches could result from stress or tension rather than a direct allergic response, and dizziness could be linked to anxiety or other health issues. In contrast, the specific and direct response of the skin to allergens in hair color products clearly indicates itching or rash as the hallmark symptom of an allergic reaction.
