- BApply a protective cream around the hairline.
- CPerform a strand test to check for elasticity and porosity.
- DDrape the client with a towel and cape.
Show answer & explanationAnswer & explanation
Correct answer: C. Perform a strand test to check for elasticity and porosity.
Before any chemical texture service, a strand test is crucial to assess the hair's current condition, elasticity, and porosity, which determines how the hair will react to the chemicals and helps prevent damage.
Why the other options are wrong
- A. Sectioning is a procedural step, not an initial safety assessment.
- B. Protective cream prevents skin irritation but doesn't assess hair's internal reaction to chemicals.
- D. Draping is important for cleanliness but not the most critical safety step for chemical reactions.
Strand Test (Chemical Texture)
A preliminary test performed on a small section of hair to determine its elasticity, porosity, and reaction to the chemical solution before a full chemical texture service.
- Assesses hair's current condition
- Prevents over-processing or damage
- Guides selection of correct processing time/solution strength
Memory trick: Strands tell tales before the perm.
