NIC Barber Written (Theory) ExamHair Care ServicesHard
A barber is performing a haircut and notices that the client's hair is extremely dry, brittle, and breaks easily, with a rough, raised cuticle. Which hair characteristic is primarily indicated by these observations?
- ALow elasticity
- BFine texture
- CHigh porosity
- DNormal porosity
Show answer & explanationAnswer & explanation
Correct answer: C. High porosity
High porosity hair has a raised or open cuticle, allowing moisture to enter and leave easily, leading to dryness, brittleness, and easy breakage. A rough, raised cuticle is a direct sign of high porosity.
Why the other options are wrong
- A. Low elasticity refers to the hair's ability to stretch and return, not directly to its porosity or cuticle condition.
- B. Fine texture refers to the diameter of individual hair strands, not its porosity or condition of the cuticle.
- D. Normal porosity hair has a slightly raised cuticle, absorbing and retaining moisture well, unlike the description.
Hair Porosity
Hair porosity refers to the hair's ability to absorb and retain moisture, determined by the condition of its cuticle layer.
- Low porosity: tightly closed cuticle, resists moisture absorption.
- Normal porosity: slightly raised cuticle, balanced moisture.
- High porosity: raised/damaged cuticle, absorbs and loses moisture quickly.
Memory trick: Raised Cuticle Means High Porosity, High Damage.
