A cosmetologist is performing a chemical relaxing service. To ensure the hair is sufficiently relaxed without over-processing, what specific test should be performed periodically during the processing time?
- APorosity test
- BElasticity test
- CStrand test
- DPatch test
Show answer & explanationAnswer & explanation
Correct answer: C. Strand test
A strand test is performed during chemical relaxing to check how quickly the hair is straightening and to determine if it has reached the desired level of relaxation, preventing over-processing.
Why the other options are wrong
- A. A porosity test is performed before the service to assess hair's absorption, not during processing.
- B. An elasticity test assesses hair strength before the service, not during the relaxing process for doneness.
- D. A patch test is for allergies before the service, not during processing.
Relaxer Strand Test
A test performed during a chemical relaxer service to check the hair's processing progress and determine when it has reached the desired straightness.
- Involves taking a small section of hair and smoothing it out
- If hair remains straight, it's processed; if it recoils, it needs more time
- Prevents over-processing, which can lead to severe damage
- Performed periodically throughout the processing time
Memory trick: To see the 'Relaxing' progress, pull a 'Strand' and give it a press.
