What is a common symptom of an allergic reaction to hair dye?

1. Itching, redness, or swelling in the area

2. Increased glossiness of hair

3. Hair turning a different color

4. Difficulty in styling

The correct answer is: Itching, redness, or swelling in the area

A common symptom of an allergic reaction to hair dye typically includes itching, redness, or swelling in the area where the dye has been applied. This response occurs when the body’s immune system reacts to certain chemicals in the hair dye, often leading to localized irritation. The reaction can manifest as contact dermatitis, which involves inflammation of the skin characterized by discomfort and visual indicators like redness and swelling. In contrast, increased glossiness of hair is generally a sign of healthy hair or a successful treatment rather than an allergic reaction. Hair turning a different color can be a desired effect of the dye rather than a symptom of an allergy. Difficulty in styling is typically related to hair texture or condition post-treatment and does not correlate with an allergic response. Understanding these symptoms is crucial for cosmetology professionals, as they play a vital role in ensuring client safety and satisfaction.
