NIC Cosmetology Written (Theory) ExamHair Care and ServicesMedium
A cosmetologist is performing a hair analysis for a client. The client's hair feels fine, is easily tangled, and has a dull appearance. When a strand is pulled taut, it breaks almost immediately. This indicates which of the following hair conditions?
- ALow elasticity
- BNormal elasticity
- CNormal porosity
- DHigh porosity
Show answer & explanationAnswer & explanation
Correct answer: A. Low elasticity
The hair breaking almost immediately when pulled taut is a direct indicator of low elasticity, meaning the hair lacks the ability to stretch and return to its original length. This condition often accompanies fine, tangled, and dull hair.
Why the other options are wrong
- B. Normal elasticity means the hair can stretch about 50% of its length and return without breaking. The client's hair breaking immediately indicates the opposite.
- C. Normal porosity refers to the hair's ability to absorb moisture, not its stretch and return. The description does not specifically indicate normal absorption.
- D. High porosity means the hair absorbs moisture quickly due to raised cuticles. While high porosity hair can be fragile, the immediate breakage when stretched specifically points to low elasticity.
Hair Elasticity
Hair elasticity is the hair's ability to stretch and return to its original length without breaking. It is an indicator of the hair's strength and health.
- Healthy hair can stretch significantly (up to 50%) when wet.
- Low elasticity means hair breaks easily when stretched.
- High elasticity means hair can stretch and return without damage.
- Affected by chemical services, heat styling, and environmental factors.
Memory trick: Healthy hair stretches like a rubber band and bounces back.
