What is the purpose of a neutralizing shampoo in a relaxer service?

• A. It re-hardens and locks the hair into its new shape by oxidation.
• B. To lighten the hair color
• C. To moisturize the hair
• D. To remove oils and restore shine

Answer: (D)

Neutralizing shampoo is used after a relaxer to thoroughly cleanse the hair and scalp of chemical residues and buildup, which helps rebalance the pH and prepare the hair for conditioning. When oils, product residues, and minerals are removed, the cuticle lays more evenly, which allows the hair to reflect light better and appear shinier. This cleansing action supports the final look after a relaxer and helps ensure the hair feels clean and refreshed.

Lightening hair, moisturizing the hair, or simply removing oils to restore shine alone aren’t the primary roles of the neutralizing step, whereas removing residues and oils to improve texture and shine fits how this shampoo supports the service.
