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?

  1. APorosity test
  2. BElasticity test
  3. CStrand test
  4. DPatch test
Show answer & 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.
