Cosmetology and Beauty Hair Care & Styling 1 — Questions and Answers
Question 1: What is the outermost layer of the hair shaft called?
- Medulla
- Cortex
- Cuticle (Correct answer)
- Papilla
Correct answer: Cuticle
The cuticle is the outermost layer, consisting of overlapping scale-like cells that protect the inner layers of the hair shaft.
Question 2: Which phase of the hair growth cycle is characterized by active hair growth?
- Telogen
- Catagen
- Exogen
- Anagen (Correct answer)
Correct answer: Anagen
The anagen phase is the active growth phase, during which the hair follicle produces new hair cells and the strand lengthens.
Question 3: What property of hair describes its ability to stretch and return to its original length without breaking?
- Porosity
- Density
- Elasticity (Correct answer)
- Texture
Correct answer: Elasticity
Elasticity measures the hair's resilience; healthy hair can stretch up to 50% when wet and spring back without breaking.
Question 4: Which layer of the hair shaft contains melanin, the pigment responsible for hair color?
- Cuticle
- Medulla
- Cortex (Correct answer)
- Follicle
Correct answer: Cortex
The cortex is the middle layer of the hair shaft and contains melanin granules that determine the hair's natural color.
Question 5: A client's hair absorbs water and product very quickly but loses moisture just as fast. This characteristic indicates:
- Low porosity
- Normal porosity
- High porosity (Correct answer)
- Zero porosity
Correct answer: High porosity
High porosity hair has raised or damaged cuticles with gaps, causing it to absorb moisture rapidly but also lose it quickly.
Question 6: What is sebum, and what is its role in hair health?
- A synthetic conditioner applied during shampooing
- A protein that builds the hair shaft structure
- The natural oil secreted by sebaceous glands that lubricates the scalp and hair (Correct answer)
- A chemical used in permanent wave solutions
Correct answer: The natural oil secreted by sebaceous glands that lubricates the scalp and hair
Sebum is produced by the sebaceous glands and naturally conditions the scalp and hair shaft, protecting it from dryness.
Question 7: Which hair texture type has the smallest diameter and is generally more fragile?
- Coarse
- Medium
- Fine (Correct answer)
- Thick
Correct answer: Fine
Fine hair has the smallest diameter per strand, making it more susceptible to breakage and requiring gentler handling.
