What is a common cause of allergic reactions to hair products?

1. Sensitivity to chemicals such as dyes or fragrances

2. Exposure to heat

3. Using too many products at once

4. Changes in weather

The correct answer is: Sensitivity to chemicals such as dyes or fragrances

A common cause of allergic reactions to hair products is sensitivity to chemicals such as dyes or fragrances. Many hair care products contain a variety of synthetic compounds, including colorants and scents, which can trigger allergic responses in some individuals. These reactions may manifest as itching, redness, swelling, or even more severe skin conditions if the person has an allergy to specific ingredients. In contrast, while exposure to heat can lead to irritation or damage to hair, it does not typically cause allergic reactions. Similarly, using multiple products at once can contribute to buildup on the hair and scalp or irritation, but it’s not directly linked to allergies. Changes in weather can affect hair and scalp conditions, but they do not usually result in allergic reactions to hair products. Sensitivity to the specific chemical components in hair products remains the primary concern regarding allergic responses.
