Texas Class A Barber Written ExamHaircutting and StylingMedium
A barber is preparing to perform a chemical relaxing service on a client with tightly coiled, resistant hair. Before applying the relaxer, the barber performs a strand test. What is the primary purpose of this test in this specific scenario?
- ATo determine the client's natural hair color.
- BTo check for potential allergic reactions to the relaxer product.
- CTo see if the hair will hold a curl after relaxing.
- DTo assess the hair's elasticity and porosity after processing.
Show answer & explanationAnswer & explanation
Correct answer: D. To assess the hair's elasticity and porosity after processing.
The strand test for a chemical relaxer primarily assesses how the hair responds to the chemical processing, specifically its elasticity and porosity, to determine the optimal processing time and ensure the hair can withstand the treatment without damage. It also confirms the desired degree of straightening.
Why the other options are wrong
- A. Natural hair color is determined during initial consultation, not typically by a relaxer strand test.
- B. An allergy patch test (predisposition test) is performed on the skin 24-48 hours prior, not a strand test on the hair.
- C. Relaxers are designed to straighten, not to make hair hold a curl; this is a misconception of the service.
Chemical Relaxer Strand Test
A preliminary test performed on a small section of hair to determine its reaction to a chemical relaxer, assess processing time, and ensure desired results and hair integrity.
- Evaluates elasticity and porosity.
- Identifies optimal processing time.
- Prevents over-processing and damage.
Memory trick: Before you relax, test the hair's flex.
