Texas Class A Barber Written ExamHaircutting and StylingHard
A barber is analyzing a client's hair for a chemical texture service. The hair feels rough, dry, and appears dull, absorbing water very quickly when wet. Which characteristic best describes this client's hair, and what implication does it have for the service?
- ALow porosity, requiring less processing time.
- BNormal elasticity, indicating healthy hair.
- CHigh porosity, requiring gentler formulas and shorter processing time.
- DFine texture, making it more susceptible to damage.
Show answer & explanationAnswer & explanation
Correct answer: C. High porosity, requiring gentler formulas and shorter processing time.
Hair that feels rough, dry, dull, and absorbs water quickly indicates high porosity. Highly porous hair has a raised cuticle, allowing rapid absorption but also rapid loss of moisture and chemicals. For chemical services, this means it will process faster and requires gentler formulas and/or shorter processing times to prevent damage. Fineness is a texture, not a porosity characteristic, and elasticity refers to stretch, not absorption.
Why the other options are wrong
- A. Low porosity hair is resistant to moisture absorption and requires longer processing time, opposite of the described characteristics.
- B. Normal elasticity refers to the hair's ability to stretch and return, not its absorption rate or texture.
- D. Fine texture describes the diameter of individual hair strands, not its porosity or absorption rate, although fine hair can often be more delicate.
High Porosity Hair
Hair with a raised or compromised cuticle layer, allowing it to rapidly absorb and lose moisture and chemical solutions, appearing rough, dry, and dull.
- Absorbs water quickly.
- Feels rough, appears dull.
- Processes faster with chemical services.
- Requires gentle products and shorter processing.
Memory trick: High porosity, high absorption, high caution.
