Which is the outermost layer of the hair shaft?
Cortex
Cuticle
Papilla
Medulla
The cuticle is the outer protective layer of the hair shaft composed of overlapping scales that protect the cortex. It contributes to hair shine and smoothness and its condition affects porosity. Damage to the cuticle can lead to dryness and breakage.
Which protein is the primary component of hair?
Collagen
Melanin
Elastin
Keratin
Hair is primarily made of keratin, a fibrous protein that gives hair its strength and resilience. Keratin is produced in the hair follicle and forms long chains. Understanding keratin is essential for hair treatments and chemical services.
The optimal pH range for hair and scalp is between:
6.5 - 7.5
4.5 - 5.5
7.5 - 8.5
2.5 - 3.5
A pH of 4.5 - 5.5 keeps the cuticle closed, retains moisture, and maintains scalp health. Alkaline pH can open the cuticle causing damage and frizz. Proper pH restores balance after chemical services.
Hair texture is primarily determined by the shape of the:
Hair bulb
Hair root
Hair shaft
Hair follicle
The follicle's shape (oval, round, or elliptical) dictates whether hair grows straight, wavy, or curly. The hair shaft reflects the follicle's geometry as it emerges. Stylists assess follicle shape to predict styling and chemical outcomes.
A styling product designed to add lift and fullness at the roots is called a:
Smoothing serum
Thermal protectant
Root lifter
Leave-in conditioner
Root lifters are lightweight sprays or foams applied at the scalp to support hair strands at the base. They create instant volume without weighing hair down. They are ideal for fine or flat hair.
Which test helps determine hair's elasticity and strength before a chemical service?
Patch test
Strand test
Porosity test
Elasticity test
An elasticity test stretches a small section of hair to check how far it stretches without breaking. It indicates hair's ability to withstand chemical processes. Low elasticity hair is more prone to breakage.
What temperature of water should be used during a professional shampoo service?
Tepid
Cold
Warm
Hot
Warm water opens the hair cuticle for thorough cleansing while remaining comfortable for the client. Hot water can irritate the scalp and strip natural oils. Cold water closes the cuticle but is less effective for cleansing.
Which layer of the hair shaft contains pigment (melanin)?
Cortex
Papilla
Medulla
Cuticle
The cortex, comprising the middle layer, holds melanin granules which give hair its color. It also provides strength and elasticity. Chemical processes primarily affect the cortex to achieve color changes.
What degree of elevation is used to achieve a blunt or one-length haircut?
90°
180°
45°
A 0° elevation keeps hair close to the head and produces a solid, weighty line typical of one-length haircuts. Higher elevations remove more weight for layering. Blunt cuts are foundational for many styles.
Which tool is best for creating precise straight partings and sections?
Wide-tooth comb
Rat-tail comb
Round brush
Paddle brush
The rat-tail comb features a fine-toothed blade and a pointed tail, ideal for neat, accurate partings and sectioning during cutting or coloring. It helps establish clean lines. Proper sectioning is key to precise results.
Which hair texture classification has the largest hair diameter?
Coarse
Extra fine
Medium
Fine
Coarse hair has the largest diameter, giving it a thicker, stronger feel than medium or fine textures. It often requires stronger chemical solutions and more heat to style. Stylists must adjust techniques accordingly.
Elevating hair to 90 degrees from the head during a haircut creates what effect?
Uniform layers
Graduation
Activated texture
Weight line
A 90° elevation (perpendicular to the head) removes weight evenly through the section, producing consistent layers. It's fundamental for layered haircut shapes. Mastery of elevation is crucial for shape control.
During a client consultation, discussing the client's lifestyle helps determine which of the following?
Maintenance expectations
Scalp condition
Hair texture
Hair density
Understanding a client's daily routines and styling habits guides realistic hairstyle and treatment recommendations. It ensures the service fits their budget and time constraints. This builds trust and satisfaction.
Which type of pin curl provides the most volume at the base?
Barrel curl
Half-stem curl
No-stem curl
Full-stem curl
Full-stem pin curls allow the hair to move freely around the base, creating maximum volume and movement. They're ideal for lifts and body. Proper stem placement controls curl direction.
Which hair characteristic most affects processing time for an alkaline permanent wave?
Density
Texture
Porosity
Elasticity
Hair porosity indicates how easily hair absorbs chemicals; higher porosity speeds processing. Resistant (low porosity) hair requires longer time or stronger solution. Evaluating porosity ensures safe, effective results.
What base control places the roller directly on its base for maximum volume?
No base
Off base
On base
Half base
On-base roller placement positions the roller 90° behind the base, creating the greatest lift and tension. It yields maximum volume at the scalp. Used for strong, uniform curls.
Which hair color type remains on the surface and washes out fastest?
Semi-permanent
Demi-permanent
Temporary
Permanent
Temporary hair color coats the cuticle without penetrating the cortex and washes out after one to two shampoos. It's ideal for testing trends. It doesn't require developer.
What is the primary purpose of using an end paper in a perm wrap?
Speed processing time
Add tension on the rod
Mark section boundaries
Prevent fishhooks and protect ends
End papers wrap the ends of hair to prevent bird's nests or fishhooks and ensure smooth, even wrapping. They protect fragile ends during chemical processing. Proper use yields uniform curl formation.
Which thermal iron has a fixed barrel diameter and clamp for uniform curls?
Hot roller
Curling wand
Marcel iron
Flat iron
Marcel irons have a clamp and fixed barrel that heats evenly for consistent curl size. They require skill to operate safely. They're versatile for wave and curl patterns.
In blow-drying, directing airflow down the hair shaft to smooth the cuticle is called:
Scrunch drying
Directional drying
Cross-ventilation
Hair wrapping
Directional drying uses the nozzle to aim airflow down the cuticle toward the ends, smoothing hair and enhancing shine. It reduces frizz and aids in sleek styles. It's fundamental in professional blowouts.
Which relaxer type uses an exothermic reaction for processing?
Acid relaxer
Thio relaxer
Sodium hydroxide relaxer
Exothermic relaxer

Which brushing technique is used to remove tangles before styling?
Teasing
Smoothing
Backbrushing
Raking
Raking involves using fingers or a wide-tooth tool to gently detangle hair from ends to roots before styling. It minimizes breakage and pain. It's essential for evenly distributing products.
What is the purpose of a filler in hair coloring services?
Seal the cuticle
Equalize porosity and fill missing pigment
Shorten processing time
Neutralize unwanted tones
Color fillers deposit a base pigment to even out porosity and replace lost melanin, ensuring uniform final tonality. They're used when hair is over-porous or has uneven previous color. Proper use prevents patchiness.
Which cutting technique involves cutting hair at a low elevation to build weight?
Layering
Slicing
Graduation
Point cutting
Graduation uses low elevation (less than 45°) to stack hair and create weight at the perimeter. It builds solid forms with a soft transition. It's key for bob and wedge shapes.
A client allergic to PPD should avoid which color service?
Permanent hair color
Temporary color
Gloss toners
Semi-permanent color
Permanent hair colors often contain PPD (para-phenylenediamine), a common allergen. Clients with sensitivity should use temporary or semi-permanent dyes without PPD. Patch testing is essential.
What term describes the angle at which hair naturally falls from the head?
Natural distribution
Growth pattern
Directional line
Natural fall
Natural fall refers to the direction hair assumes when it falls free from the head. Recognizing it helps in accurate cutting and styling. It influences sectioning and elevation decisions.
In hair coloring, a diagonal weave sectioning pattern is used to:
Frame the face softly
Create a bold mohawk effect
Isolate resistant gray hair
Ensure even saturation on the perimeter
Diagonal weave sections distribute color more subtly and blend the hairline, giving natural-looking highlights. It prevents harsh lines and ensures even coverage. It's popular for face-framing accents.
During a virgin relaxer service, processing time should be based on:
Recommended time on the box only
Room temperature
Client's scalp sensitivity exclusively
Hair type, texture, and porosity
Processing time varies by hair texture, porosity, and previous chemical history. Fine or porous hair requires less time, coarse hair requires more. Following manufacturer guidelines and strand testing ensures safety.
Which perm rod size creates the tightest, most defined curls?
Small rods
Extra-large rods
Large rods
Medium rods
Small perm rods wrap hair into tighter spirals, producing defined, springy curls. Larger rods yield looser waves. Rod size selection is key for desired curl pattern.
In the croquinole perm wrapping technique, hair is wrapped in layers:
From base to ends
From ends to base
Randomly placed
Only mid-shaft
Croquinole wrapping overlaps each layer from the ends up toward the base, ensuring smooth curl transitions. It produces tighter curls near the ends and looser at the base. Technique controls curl consistency.
What is the primary active ingredient in most permanent wave neutralizers?
Ammonium thioglycolate
Hydrogen peroxide
Sodium bromate
Glycerin
Neutralizers commonly contain hydrogen peroxide to rebuild disulfide bonds formed during the waving process. It halts the chemical reaction and stabilizes the new curl shape. Proper neutralization restores hair strength.
When using the scissor-over-comb haircutting technique, the comb should be held:
At 45° angle
At 90° angle
Perpendicular to the head
Parallel to the head
In scissor-over-comb, the comb sits parallel to the scalp to lift hair uniformly while the shears slide across the comb teeth. This technique creates smooth fades and tapers. Control of angle yields precision.
Which relaxer requires heat from the stylist to activate?
No-lye relaxer
Exothermic relaxer
Thio relaxer
Endothermic relaxer
Endothermic relaxers require external heat (hood dryer or steam) to activate the chemical smoothing process. They're gentler but take longer. Monitoring temperature and time prevents overprocessing.
For a square face shape, which haircut best softens angular features?
Soft layers and waves
Straight, heavy fringe
Blunt bob at jawline
Severe pixie cut
Soft, flowing layers and waves help break up the strong jawline of a square face. They add roundness and movement, balancing angles. Styling with texture creates a more oval illusion.
A porosity test assesses hair's ability to:
Absorb moisture and chemicals
Conduct electricity
Resist breakage
Stretch under tension
Porosity testing, such as the float test or strand absorption, indicates how readily hair takes up water and chemicals. High porosity hair processes faster but can be over-processed. Low porosity hair may require more aggressive techniques.
Acid-balanced permanent waving lotions typically have a pH around:
6.9 - 7.2
4.5 - 5.5
10.0 - 11.5
8.0 - 9.5
Acid-balanced waves (glyceryl monothioglycolate-based) process at a pH close to 7, minimizing cuticle lift and reducing damage. They're gentler and produce softer curls. They are preferred for fragile hair.
Which color technique uses a zigzag parting to create dimension?
Balayage
Backcombing
Weaving
Slicing
Weaving uses a zigzag part to pick fine sections for highlights or lowlights, creating a natural blend. It controls color concentration and dimension. Proper tension and timing yield seamless effects.
Which shears have one straight blade and one blade with teeth to remove bulk?
Cutting shears
Razor
Texturizing razor

Mild-strength relaxers are formulated for fine or fragile hair, reducing the risk of overprocessing. They contain lower active ingredient concentration. Selecting the correct strength is essential for hair health.
When layering hair using scissor-over-comb, tension primarily affects:
Cuticle alignment
Weight distribution
Color absorption
Porosity level
Tension controls how much hair is lifted from the scalp, directly affecting where the weight line falls. More tension yields shorter layers, less tension maintains weight. Proper tension ensures consistent form.
Underprocessing a perm wrap will result in:
Complete straightening
Weak, loose curls
Immediate breakage
Overly tight curls
Insufficient processing time prevents proper breakage and rebuilding of disulfide bonds, yielding weak rod formation. Curls may drop quickly or look limp. Accurate timing and strand tests prevent this.
After applying a sodium hydroxide relaxer, how long should you rinse per inch of hair?
30 seconds per inch
1 minute per inch
2 minutes total
5 minutes total
Manufacturers recommend rinsing each inch of relaxed hair for about one minute to remove all chemical residues. Inadequate rinsing can lead to scalp irritation. Thorough rinsing is essential for hair health.
Which bond in hair protein is chiefly responsible for elasticity and strength?
Peptide bonds
Disulfide bonds
Salt bonds
Hydrogen bonds
Disulfide bonds link cysteine amino acids in the cortex and provide hair with strength and resilience. They are altered during chemical services like perms and relaxers. Understanding bond structure is crucial for advanced texturizing.
Which perm wrap technique is ideal for very long hair using two end papers?
Piggyback wrap
Spiral wrap
Basic block wrap
Bricklay pattern
The piggyback wrap uses two rods per section with one rod at the base and another at the ends, ensuring even processing on long hair. It prevents weak spots and uneven curl. Mastery of wrap patterns yields professional results.
What effect does a soft bender rod have compared to a standard rod in thermal styling?
Creates a tighter curl
Lifts roots only
Produces a soft wave
Smooths hair without curl
Soft bender rods are flexible soft-metal tools that create gentle, uniform waves rather than tight spirals. They're ideal for soft texturizing. They require precise heat control for desired results.
For an alkaline perm, which hair type will process fastest?
Fine, non-porous hair
Medium, normal hair
Coarse, resistant hair
Fine, porous hair
Fine, porous hair allows alkaline solutions to penetrate quickly, breaking disulfide bonds faster than in coarse or low-porosity hair. It requires shorter processing times to avoid overprocessing and damage. Strand testing is always recommended.

Cheat Sheet

  1. Color Theory Fundamentals -

    Understanding primary, secondary, and complementary colors is essential for accurate haircolor formulations on your cosmetology mock test and hair stylist quiz (Milady's Standard Cosmetology). Remember ROYGBIV to distinguish warm from cool tones and the 1 - 10 level system for lift and deposit. For instance, a violet-based toner counteracts yellow undertones in blonde hair.

  2. Pincurl Movement Determinants -

    In many hairdressing tests you'll be asked what determines the amount of movement a pincurl will have, and it depends on base size, shaping, and placement on the head (Pivot Point Study Guide, 2019). Larger bases produce more volume and movement, while smaller bases yield tighter, more defined curls. Use square, triangular, or arc bases strategically when practicing hairdressing exam questions and answers.

  3. Sectioning and Parting Precision -

    Effective hairdressing tests often include questions on subsection patterns like horizontal, vertical, and diagonal slices (American Academy of Cosmetology). Practicing consistent 1/4-inch subsections ensures even product application and clean cutting lines. Try visualizing a clock around the head to maintain balanced quadrants during styling.

  4. Client Consultation and Hair Analysis -

    Use a five-point hair & scalp analysis - density, elasticity, porosity, texture, and scalp condition - to tailor services on your hair stylist quiz (Dermatest Research Journal, 2021). The acronym "PESTS" helps you remember Porosity, Elasticity, Scalp, Texture, and Density. Document thoroughly to ensure safety and personalized results during the real exam.

  5. Sanitation and Safety Standards -

    Memorize EPA-registered disinfectants and OSHA guidelines for tool sanitation to prevent cross-contamination in your hairdressing exam questions and answers (OSHA Technical Manual).
