What is the main health issue a cosmetologist may experience?

• A. Asthma
• B. Hypersensitivity
• C. Dermatitis
• D. Migraine

Answer: (B)

The main concept here is an exaggerated immune response to substances encountered in the salon. Hypersensitivity means the immune system overreacts to a chemical that isn’t harmful to most people, such as fragrances, preservatives, hair dye ingredients, or solvents. With repeated exposure, a person can become sensitized, so even small amounts cause symptoms. Those symptoms often manifest on the skin as dermatitis—redness, itching, swelling or a rash—and can occasionally involve breathing issues as well. Dermatitis is a common result of hypersensitivity, but hypersensitivity describes the overall mechanism behind these reactions. Asthma and migraines are separate conditions and aren’t the primary mechanism described, while dermatitis is a possible outcome rather than the broader concept.
