Which tool is specifically designed to detangle wet hair without causing breakage?
Razor comb
Fine-toothed comb
Round brush
Wide-tooth comb
A wide-tooth comb has widely spaced teeth that gently separate strands without snagging, making it ideal for wet hair detangling. The spacing reduces stress and breakage compared to finer combs.
Which layer of the hair shaft is responsible for protecting the cortex?
Medulla
Fibrous sheath
Cortex
Cuticle
The cuticle is the outermost layer of the hair shaft composed of overlapping scale-like cells that protect the inner cortex. Its condition directly affects hair shine and smoothness.
Which personal protective equipment (PPE) is essential when mixing chemical hair treatments?
Apron
Gloves
Goggles
Mask
Gloves create a barrier that protects the stylist's skin from chemical irritants and potential allergic reactions. They are a fundamental PPE item when handling hair treatments.
What hair type describes strands that are fine in diameter and may lack volume?
Coarse hair
Curly hair
Medium hair
Fine hair
Fine hair refers to strands with a small diameter, which often appear limp and lack volume. Texture affects styling choices and product needs.
What is the primary purpose of sectioning hair before a haircut or style?
To simplify cutting into manageable areas
To change hair colour
To add product evenly
To increase hair volume
Sectioning breaks the hair into organized parts, making cutting and styling more precise and efficient. It ensures consistency and control over the process.
What is the ideal pH range for hair and scalp health?
6.5 to 7.5
2.0 to 3.0
8.0 to 9.0
4.5 to 5.5
The natural pH of hair and scalp falls between 4.5 and 5.5, which helps maintain cuticle integrity and prevents microbial growth. Products formulated within this range support moisture balance and shine.
During an elasticity test, healthy hair will stretch and return to its original length without breaking at approximately what percentage?
20%
50%
80%
5%
Healthy hair can stretch up to about 50% of its original length and still return without damage, indicating sufficient moisture and intact keratin bonds. Lower elasticity may signal damage or porosity issues.
A client has brittle, over-processed hair. Which treatment is most appropriate to strengthen the hair structure?
Clarifying shampoo
Protein filler treatment
Moisturizing rinse
Dry cut
Protein filler treatments rebuild and reinforce the hair's internal structure by filling in gaps in the cortex created by chemical damage. This helps restore strength before further services.
What is the main reason for disinfecting tools between clients?
To apply lubricant
To polish tool surfaces
To prevent cross-contamination
To maintain sharpness
Disinfecting tools eliminates pathogens that could transfer from one client to another, ensuring a safe salon environment. Proper disinfection protocols protect both client and stylist health.
Which toner shade should be used to neutralize brassy orange tones in pre-lightened hair?
Purple
Yellow
Green
Blue
Blue is opposite orange on the colour wheel, so blue-based toners cancel out brassy orange casts. Choosing the correct complementary shade ensures neutralization of unwanted warmth.
Which hair shaft component provides tensile strength and elasticity?
Medulla
Cuticle
Cortex
Sheath
The cortex contains keratin bundles and melanin, giving hair most of its strength and flexibility. Damage to the cortex reduces elasticity and resilience.
A client presents with dry hair prone to breakage. Which routine should you recommend?
Protein and moisture reconstructor
Daily bleaching sessions
Frequent clarifying treatments
High-pH styling products
Protein and moisture reconstructors balance the hair's moisture-protein ratio, improving strength and elasticity. This treatment is ideal for combating dryness and breakage.
Which cutting technique creates a soft, blended graduation between lengths?
Razor slicing
Clipper over comb
Blunt cutting
Point cutting
Point cutting uses the shears' tips to snip into the hair ends at an angle, softening lines and blending layers. It reduces bulk without harsh, straight edges.
What is required before applying a pastel hair dye to achieve an even result?
No prior preparation
Neutral-level base hair
Applying a red base
Pre-lightening to pale yellow
Pastel dyes have low pigment and require the hair to be lifted to a pale yellow stage to ensure the final tone appears true. Insufficient lift leads to muted or uneven pastel results.
When performing a skin patch test for hair dye, how long should you wait before assessing for a reaction?
30 minutes
15 minutes
24 to 48 hours
5 days
A 24 - 48 hour patch test period allows time for delayed allergic reactions to develop, ensuring client safety. Shorter tests might miss sensitization symptoms.
Which colour does a green-based toner neutralize in hair?
Yellow
Blue
Red
Orange
Green is opposite red on the colour wheel, making green-based toners effective at cancelling red undertones. Correct neutralization restores a balanced neutral shade.
What type of bond in the hair structure is primarily responsible for temporary changes in shape, such as styling with water and heat?
Disulfide bond
Salt bond
Hydrogen bond
Peptide bond
Hydrogen bonds are weak links between keratin chains that can be broken and reformed by water and heat, allowing temporary style changes. They are reestablished as hair dries or cools.
To lift natural hair from level 4 to level 8, how many levels of lift are necessary?
8 levels
4 levels
2 levels
6 levels
Moving from level 4 to level 8 requires a four-level lift, as each level corresponds to one step lighter. Accurate lift planning helps avoid overprocessing or uneven results.
Which developer volume produces the least lightening effect with minimal lift?
30 volume (9% peroxide)
20 volume (6% peroxide)
5 volume (1.5% peroxide)
10 volume (3% peroxide)
A 5 volume developer contains about 1.5% hydrogen peroxide, which provides minimal lift and is ideal for slight deposit or tone adjustment without significant lightening. Higher volumes increase lift potential.
Which disinfectant is classified as high-level and capable of destroying bacterial spores in the salon?
Quaternary ammonium compounds
Isopropyl alcohol
Sodium hypochlorite (household bleach)
Glutaraldehyde
Glutaraldehyde is a high-level disinfectant effective against bacteria, viruses, fungi, and bacterial spores when used according to manufacturer instructions. It is suited for tools requiring spore-level disinfection.
