A barber is analyzing a client's hair for a chemical service. The client's hair feels rough, absorbs moisture quickly, and appears dull. This indicates which type of hair porosity?
- AHigh porosity
- BNormal porosity
- CLow porosity
- DResistant porosity
Show answer & explanationAnswer & explanation
Correct answer: A. High porosity
High porosity hair has a raised cuticle layer, allowing it to absorb moisture quickly but also lose it quickly. This often results in hair that feels rough, appears dull, and can be easily damaged.
Why the other options are wrong
- B. Normal porosity hair has a healthy cuticle and absorbs/retains moisture well.
- C. Low porosity hair has a tightly closed cuticle, making it difficult to absorb moisture.
- D. Resistant porosity is often synonymous with low porosity, indicating difficulty absorbing products.
High Porosity Hair
Hair with a raised or damaged cuticle layer, allowing moisture and chemicals to be absorbed quickly but also lost quickly. It often appears dull, feels rough, and is prone to damage.
- Cuticle layer is raised/damaged
- Absorbs moisture and products quickly
- Loses moisture quickly
- Feels rough, appears dull, prone to frizz and damage
Memory trick: High porosity is like a sieve; water goes in fast, but comes out just as fast.
