NIC Cosmetology Written (Theory) ExamHair Care and ServicesMedium
A cosmetologist is performing a hair analysis for a client who desires a permanent wave. The client's hair feels fine, limp, and lacks elasticity when stretched, returning slowly or not at all to its original state. What does this indicate about the hair's condition?
- ANormal porosity
- BGood elasticity
- CLow elasticity
- DHigh porosity
Show answer & explanationAnswer & explanation
Correct answer: C. Low elasticity
When hair lacks elasticity and returns slowly or not at all to its original state after being stretched, it indicates low elasticity. Hair with low elasticity is weak and may not hold a permanent wave well, or could be easily damaged by the chemical process.
Why the other options are wrong
- A. Normal porosity refers to adequate moisture absorption, not elasticity.
- B. Good elasticity means the hair stretches and returns to its original length without breaking, which is the opposite of the client's condition.
- D. High porosity refers to the hair's ability to absorb moisture, not its stretch and return capability.
Hair Elasticity
The ability of the hair to stretch and return to its original length without breaking. It indicates the hair's strength and internal health.
- Healthy hair stretches about 50% when wet and returns to original length.
- Low elasticity indicates weak or damaged hair.
- High elasticity indicates strong, healthy hair.
- Crucial test before chemical services like perms or relaxers.
Memory trick: Elasticity: Does it STRETCH and SNAP BACK, or just FOLD?
