  1. AApply a deep conditioning treatment.
  2. BApply a leave-in conditioner.
  3. CShampoo with a neutralizing shampoo.
  4. DPerform a strand test.
Show answer & explanation

Correct answer: C. Shampoo with a neutralizing shampoo.

After thoroughly rinsing a chemical relaxer, a neutralizing shampoo must be used immediately to stop the chemical process and restore the hair's pH, preventing further damage.

Why the other options are wrong

  • A. Deep conditioning is done after neutralizing, not before, as it doesn't stop the chemical action.
  • B. Leave-in conditioner is applied after the hair has been neutralized and conditioned, not as a neutralizing step.
  • D. A strand test is performed before the relaxer application, not after rinsing.

Neutralizing Shampoo (Relaxers)

A specialized shampoo, typically containing a pH indicator, used after a chemical relaxer service to stop the action of the relaxer, remove residual chemicals, and restore the hair and scalp to a normal pH range.

  • Crucial step to prevent over-processing and damage.
  • Often turns pink or purple if relaxer residue is present, indicating more rinsing is needed.
  • Contains ingredients to re-harden the disulfide bonds in their new straight configuration.

Memory trick: Neutralize to stabilize.
