A key sign of an allergic reaction during a chemical service is the presence of redness, itching, or swelling on the scalp or skin. These symptoms indicate that the body is responding negatively to a substance, often due to the immune system recognizing it as a potential threat. In a chemical service, such reactions can occur in response to hair dyes, relaxers, or other products containing strong chemicals.

The other options do not represent signs of an allergic reaction. Increased hair growth might suggest hormonal changes or other biological factors rather than an allergy. Dryness of the scalp could be a result of chemical processes but doesn’t indicate an allergic response specifically. Hair color fading is typically related to product performance, exposure to environmental factors, or improper application rather than a sign of an allergic reaction. Therefore, recognizing the symptoms of redness, itching, or swelling is crucial for identifying potential allergic reactions and ensuring the safety and well-being of clients during chemical services.
