A cosmetologist is performing a chemical relaxer service using a hydroxide relaxer on a client with extremely curly, resistant hair. After the processing time, the hair is rinsed thoroughly. What is the MOST crucial next step to ensure the chemical process is completely stopped and the hair's pH is restored?
- AApplying a deep conditioning treatment.
- BApplying a neutralizing shampoo.
- CPerforming a strand test for elasticity.
- DRe-applying a small amount of relaxer to resistant areas.
Show answer & explanationAnswer & explanation
Correct answer: B. Applying a neutralizing shampoo.
After rinsing a hydroxide relaxer, it is crucial to apply a neutralizing shampoo. Hydroxide relaxers are highly alkaline and cannot be neutralized by merely rinsing with water. The neutralizing shampoo chemically stops the relaxer's action and helps restore the hair's pH to an acidic state, preventing further damage.
Why the other options are wrong
- A. A deep conditioning treatment is important for hair health but does not chemically neutralize the relaxer.
- C. A strand test for elasticity is performed during the processing to check for readiness, not after rinsing.
- D. Re-applying relaxer after rinsing would cause severe over-processing and damage.
Neutralizing Shampoo (Hydroxide Relaxers)
A shampoo specifically formulated with an acidic pH to halt the chemical action of highly alkaline hydroxide relaxers and restore the hair's natural pH balance.
- Used immediately after rinsing hydroxide relaxers.
- Contains a pH balancer (typically acidic).
- Stops the relaxer's processing to prevent over-processing and damage.
- Essential for restoring hair's integrity post-relaxer.
Memory trick: Neutralize the ALKALINE, or the hair will decline!
