The primary reducing agent in alkaline permanent wave solutions is
A is applied after permanent wave processing to re-form disulfide bonds
Sodium is a strong alkali used in lye-based chemical relaxers
cream is applied to protect the scalp before a chemical relaxer service
bonds are strong chemical bonds in the cortex that are broken during perming and relaxing
An exothermic wave creates its own during the chemical reaction
A wave requires an outside heat source to activate the processing
Chemical relaxers work by permanently breaking and reforming bonds in the cortex
Multiple Choice
Select the best answer for each board-exam style question.
The purpose of a permanent wave neutralizer is to:
Which chemical is the primary active ingredient in lye-based relaxers?

During a permanent wave, the hair wrapping technique affects the:
An acid wave has a pH of approximately:
An alkaline wave has a pH of approximately:
Which of the following is a safety precaution for chemical texture services?
The hair bond that determines curl pattern and is altered during chemical texture services is the:
True / False
Write T for True or F for False in the blank.
A permanent wave can be performed on hair that has been previously relaxed.
Neutralizing is the final and most critical step of a permanent wave service.
Lye-based relaxers are milder than no-lye relaxers.
A strand test helps determine processing time and the hair ability to withstand chemical services.
Disulfide bonds can be temporarily broken with water.
An exothermic wave generates heat internally, while an endothermic wave requires an outside heat source.
Base cream prevents the relaxer from working properly.
Chemical texture services permanently alter the structure of the hair cortex.
Short Answer
Answer each question in 2-3 complete sentences.
Explain the chemical process that occurs during a permanent wave service, from the reducing agent through neutralization.
Compare lye-based and no-lye relaxers, including their active ingredients, pH levels, and appropriate uses.
Why are strand tests and patch tests essential before performing any chemical texture service?
