Show answer & explanationAnswer & 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.
