A cosmetologist is performing a permanent wave service. After rinsing the perm solution from the hair, what is the primary function of the neutralizer?
- ATo swell the hair shaft for better curl formation.
- BTo break down additional disulfide bonds.
- CTo re-harden the hair and fix the new curl pattern.
- DTo cleanse the hair of any remaining perm solution.
Show answer & explanationAnswer & explanation
Correct answer: C. To re-harden the hair and fix the new curl pattern.
The neutralizer in a permanent wave service has two main functions: to re-bond the disulfide bonds in their new shape and to re-harden the hair, thereby fixing the new curl pattern.
Why the other options are wrong
- A. Swelling occurs during the waving lotion application, not neutralization.
- B. The waving lotion breaks down disulfide bonds; the neutralizer rebuilds them.
- D. Rinsing removes the perm solution; the neutralizer performs a chemical function.
Perm Neutralizer Function
The chemical process of re-bonding the disulfide bonds in their new curled shape and re-hardening the hair to permanently set the curl pattern after a permanent wave service.
- Oxidizes and re-forms disulfide bonds.
- Typically contains hydrogen peroxide.
- Crucial for the longevity and integrity of the perm.
Memory trick: Neutralizer 'Nails' the new curl by 'N'etting the bonds back together.
