Texas Class A Barber Written ExamChemical ServicesHard
A barber is performing a permanent wave service and observes that the client's hair has very low elasticity. What adjustment should the barber consider making to the service to prevent damage?
- ASelect larger perm rods and a milder waving lotion
- BDecrease the amount of neutralizer applied
- CUse a stronger (more alkaline) waving lotion
- DIncrease the processing time of the waving lotion
Show answer & explanationAnswer & explanation
Correct answer: A. Select larger perm rods and a milder waving lotion
Low elasticity indicates fragile hair. Using larger rods creates a looser curl, requiring less strain on the hair. A milder waving lotion reduces the chemical impact, preventing further damage.
Why the other options are wrong
- B. Decreasing neutralizer would prevent proper bond reformation, leading to a weak, unset perm and potential damage.
- C. A stronger, more alkaline lotion would further weaken already fragile hair.
- D. Increasing processing time on hair with low elasticity will likely lead to over-processing and breakage.
Perm Adjustments for Low Elasticity
For hair with low elasticity, use larger perm rods for a looser curl and a milder waving lotion to minimize damage.
- Low elasticity = compromised hair strength
- Gentler chemicals and less tension are key
- Test strand is crucial
Memory trick: Low elasticity needs 'Large' rods and 'Light' lotion to avoid a 'Loose' outcome.
