  1. AApply a protein treatment
  2. BThoroughly shampoo with a neutralizing shampoo
  3. CPerform a strand test
  4. DDeep condition the hair
Show answer & explanation

Correct answer: B. Thoroughly shampoo with a neutralizing shampoo

After rinsing a chemical relaxer, it is crucial to use a neutralizing shampoo to lower the pH of the hair and scalp, halting the chemical process and preventing over-processing or damage.

Why the other options are wrong

  • A. Protein treatments are typically applied after neutralization and conditioning, not before.
  • C. A strand test is performed before the service to determine processing time, not after rinsing the relaxer.
  • D. Deep conditioning is done after neutralization to restore moisture and strength, not before.

Neutralizing Shampoo (Relaxers)

A specialized shampoo used after a chemical relaxer to stop the relaxing process by lowering the hair's pH and removing chemical residues.

  • Contains an indicator that changes color if relaxer residue is present.
  • Helps restore the hair and scalp to a normal pH range.
  • Prevents continued chemical processing and damage.

Memory trick: Relaxer Rinsing Requires Restoring pH with Neutralizing Shampoo.
