Cosmetology Test Chemical Texture Services 2 — Questions and Answers
Question 1: What is the primary purpose of a neutralizer in a permanent wave service?
- To soften and swell the hair cuticle
- To stop the waving action and rebuild disulfide bonds (Correct answer)
- To add moisture and condition the hair
- To remove excess waving solution from the hair
Correct answer: To stop the waving action and rebuild disulfide bonds
The neutralizer stops the chemical waving action and uses oxidation to rebuild the disulfide bonds in the new waved position.
Question 2: Which type of hair is most resistant to chemical texture services and may require a longer processing time?
- Fine, porous hair
- Color-treated hair
- Coarse, low-porosity hair (Correct answer)
- Previously relaxed hair
Correct answer: Coarse, low-porosity hair
Coarse, low-porosity hair has a tightly packed cuticle that resists chemical penetration, requiring longer processing time.
Question 3: A client's hair breaks during a strand test for a relaxer. What should the cosmetologist do?
- Proceed cautiously with a milder relaxer
- Apply a protein treatment and reschedule the service (Correct answer)
- Add more base cream and continue the application
- Dilute the relaxer with water before applying
Correct answer: Apply a protein treatment and reschedule the service
Hair breakage during a strand test indicates the hair is too compromised to safely receive a chemical relaxer; the service should be postponed.
Question 4: What does 'thio' refer to in the context of permanent wave chemistry?
- Thioglycolate, the active reducing agent (Correct answer)
- Thermal heat activation required
- The pH level of the waving solution
- A type of alkaline neutralizer
Correct answer: Thioglycolate, the active reducing agent
Thio refers to ammonium thioglycolate (ATG), the reducing agent that breaks disulfide bonds in traditional alkaline perms.
Question 5: Which perm rod placement technique creates a uniform wave pattern throughout all the hair?
- Piggyback wrap
- Curvature perm
- Straight set (nine-block) (Correct answer)
- Bricklay pattern
Correct answer: Straight set (nine-block)
A straight set or nine-block pattern uses consistent horizontal sections that create a uniform wave throughout the entire head.
Question 6: What is the correct action if waving lotion accidentally contacts a client's eyes during a perm service?
- Apply neutralizer immediately to the eye area
- Flush the eye with cool water for 15 minutes and seek medical attention (Correct answer)
- Blot with a dry towel and monitor the client
- Apply an eye drop solution and continue the service
Correct answer: Flush the eye with cool water for 15 minutes and seek medical attention
Chemical contact with the eyes requires immediate flushing with cool water for at least 15 minutes and referral for medical evaluation.
Question 7: A sodium hydroxide relaxer has a pH of approximately:
- 4.5 to 5.5
- 6.5 to 7.5
- 9.0 to 10.0
- 12.0 to 14.0 (Correct answer)
Correct answer: 12.0 to 14.0
Sodium hydroxide (lye) relaxers are highly alkaline with a pH ranging from 12 to 14, the highest of any professional chemical service.
