Texas Class A Barber Written ExamChemical ServicesMedium
A client requests a permanent wave, but during the consultation, the barber performs an elasticity test and the hair stretches significantly and does not return to its original length. What does this indicate about the client's hair?
- AThe hair has normal elasticity and is suitable for perming.
- BThe hair has poor (low) elasticity and is not in suitable condition for perming.
- CThe hair has high elasticity and will absorb chemicals quickly.
- DThe hair has average elasticity and requires a stronger waving solution.
Show answer & explanationAnswer & explanation
Correct answer: B. The hair has poor (low) elasticity and is not in suitable condition for perming.
Hair that stretches significantly and does not return to its original length indicates poor or low elasticity, meaning the hair is weak and potentially damaged, and therefore not suitable for a chemical service like a permanent wave without risking severe damage.
Why the other options are wrong
- A. Normal elasticity means the hair stretches and returns to its original length without breaking.
- C. High elasticity would mean it stretches, but still returns, indicating good strength.
- D. Hair with poor elasticity requires a milder solution or no chemical service at all, not a stronger one.
Hair Elasticity Test Results
Hair stretching significantly without returning indicates poor elasticity, meaning it's weak and unsuitable for harsh chemical services.
- Healthy hair stretches 20-50% wet and returns
- Poor elasticity = compromised disulfide bonds
- Chemical services can cause breakage
Memory trick: If hair 'Stretches and Stays,' it's 'Stressed' and 'Sick.'
