NIC Barber Written (Theory) ExamHair Care ServicesEasy
A barber is analyzing a client's hair during a consultation for a chemical service. The client's hair feels smooth, has a healthy sheen, and appears to repel water slightly when misted. Which of the following best describes the porosity of this client's hair?
- AUneven porosity
- BNormal porosity
- CHigh porosity
- DLow porosity
Show answer & explanationAnswer & explanation
Correct answer: D. Low porosity
Hair that feels smooth, has a healthy sheen, and repels water slightly typically indicates low porosity. This means the cuticle layers are tightly closed, making it harder for moisture to penetrate but also harder for it to escape.
Why the other options are wrong
- A. Uneven porosity would show variations in absorption and texture across different sections of hair.
- B. Normal porosity hair would absorb and retain moisture without extreme resistance or rapid loss.
- C. High porosity hair would feel rough, look dull, and absorb water quickly.
Low Porosity Hair
Hair with tightly closed cuticle layers, making it difficult for moisture to penetrate or escape. It often appears smooth, shiny, and resists chemical processing.
- Cuticles are tightly packed and lie flat.
- Resists water absorption, causing it to bead on the surface.
- Often appears shiny and healthy.
- Can be resistant to chemical services like coloring or perming.
Memory trick: Low porosity: 'Like a sealed submarine, water just slides right off!'
