Which product acts as a barrier to caustic chemicals during a relaxer retouch or chemical service?

• A. Protective cream
• B. Conditioning treatment
• C. Neutralizing shampoo
• D. Curl reform

Answer: (A)

Barrier protection during chemical services is essential because caustic chemicals can irritate or burn skin. A barrier cream forms a protective layer on the skin around the hairline and ears, preventing direct contact with the chemicals during a relaxer retouch. This reduces the risk of chemical burns and irritation and also helps keep cleanup easier if any product touches the skin. The other products serve different roles: a conditioning treatment nourishes and moisturizes hair, a neutralizing shampoo stops the chemical reaction and cleanses the hair, and curl reform is used to reshape texture—not to protect the skin from chemical exposure.
