After a relaxing treatment, a neutralizing shampoo should be applied to the hair because this step is critical in halting the chemical process used during the relaxation treatment. Relaxers alter the hair's structure, and it is important to neutralize any remaining chemicals to prevent further damage and ensure the hair returns to a pH level that promotes health and stability.

Neutralizing shampoo typically contains ingredients that help restore the hair's natural pH balance and protect it from damage, strengthening the hair after the chemical treatment. This step also helps remove any residual relaxer and prepares the hair for subsequent conditioning treatments.

Using a moisturizing conditioner, leave-in conditioner, or hair mask, although beneficial at various stages, is not the immediate priority after a relaxer. These products are typically used after the neutralizing process to provide hydration and nourishment to the hair.
