California Cosmetology Written ExamClient Consultation and AnalysisMedium
A cosmetologist performs a porosity strand test and finds that the cuticle is raised and open, causing the hair to absorb moisture and chemicals very rapidly and potentially process too quickly. How should the cosmetologist adjust the chemical service for this hair?
- AApply the product to dry, unwashed hair with no adjustments
- BIncrease the processing time beyond standard recommendations
- CUse the manufacturer's standard full processing time
- DReduce the processing time and monitor the service closely
Show answer & explanationAnswer & explanation
Correct answer: D. Reduce the processing time and monitor the service closely
High porosity hair has a raised, open cuticle that absorbs chemicals quickly, so processing time should be reduced and the service closely monitored to prevent overprocessing and damage.
Why the other options are wrong
- A. Porosity adjustment is unrelated to washing status and doesn't address the processing time issue.
- B. Increasing time would cause overprocessing and damage.
- C. Standard time may overprocess highly porous hair.
High Porosity Hair
Hair with a raised, open cuticle that absorbs moisture and chemicals quickly, requiring reduced processing times.
- Cuticle is raised/open, often from damage or chemical services
- Absorbs product faster than normal porosity
- Requires shorter processing time and close monitoring
Memory trick: High porosity = sponge — soaks up fast, so don't over-soak
