The symptoms of an allergic reaction to hair dye primarily include redness, swelling, or rash on the scalp. When a person has an allergy to certain ingredients in hair dye, their immune system reacts to those substances as though they are harmful invaders. This can lead to localized inflammation, manifesting as redness, swelling, or the development of a rash. These symptoms are a direct response of the skin to allergens in the dye, indicating the body's attempt to fight off what it perceives as a threat.

Recognizing these symptoms is crucial for both personal safety and professional practice, as it signals the need to discontinue use of the product and potentially seek medical advice. Other options, such as dryness and split ends, increased hair loss, or frizz and tangling, while they might occur due to other factors like environmental damage or poor hair care practices, do not specifically indicate an allergic reaction. These conditions do not arise from an immediate immune response, but rather from hair health issues that are unrelated to an allergy. Understanding these distinctions aids in appropriate responses to client concerns and effective hair care practices.
