Question 1Hair Care and Hairdressing

Which layer of the hair shaft contains the pigment that gives hair its natural color?

  1. The cuticle
  2. The cortex Correct answer.
  3. The medulla
  4. The follicle

Explanation

Melanin pigment is deposited in the cortex, the thick middle layer of the hair shaft. The cuticle is the outer protective layer and the medulla is the innermost core.

Question 2Hair Care and Hairdressing

Which of the following describes the resting phase of the hair growth cycle?

  1. Catagen
  2. Mitogen
  3. Anagen
  4. Telogen Correct answer.

Explanation

Telogen is the resting phase, when growth stops and the hair is eventually shed. Anagen is active growth and catagen is the transitional phase.

Question 3Hair Care and Hairdressing

Which type of hair has the largest diameter and usually contains a medulla?

  1. Lanugo hair
  2. Terminal hair Correct answer.
  3. Intermediate hair
  4. Vellus hair

Explanation

Terminal hair is the coarse, pigmented hair found on the scalp, eyebrows, and (after puberty) the body. It is thicker than vellus hair and often has a medulla.

Question 4Hair Care and Hairdressing

What does the pH scale measure in a hair product?

  1. The amount of fragrance in the product
  2. The acidity or alkalinity of the product Correct answer.
  3. The protein content of the product
  4. The thickness of the product

Explanation

pH measures how acidic or alkaline a solution is, on a scale from 0 to 14. This matters in hair care because high-pH products open the cuticle and low-pH products help close it.

Question 5Hair Care and Hairdressing

Which shampoo ingredient is primarily responsible for lifting oil and debris from the hair and scalp?

  1. Humectant
  2. Surfactant Correct answer.
  3. Thickener
  4. Preservative

Explanation

Surfactants lower surface tension so water can surround and lift oils and dirt for rinsing away. Humectants attract moisture, preservatives prevent microbial growth, and thickeners adjust viscosity.

Question 6Hair Care and Hairdressing

When holding a comb for a blunt haircut, the comb is generally used to do which of the following?

  1. Measure the tension of the section
  2. Control and distribute the hair while cutting Correct answer.
  3. Sharpen the shear blades
  4. Test the porosity of the ends

Explanation

The comb guides, sections, and holds hair in place while the shear does the cutting. It is a control and distribution tool, not a measuring or sharpening device.

Question 7Hair Care and Hairdressing

Which of the following is the correct procedure for draping a client for a wet hair service?

  1. Drape only the shoulders and leave the neck exposed
  2. Use a towel over the cape with the cape against the skin
  3. Place a towel around the neck under a waterproof cape Correct answer.
  4. Place the cape directly against the skin with no towel

Explanation

A towel absorbs moisture at the neckline while the waterproof cape protects the client's clothing. The cape should not sit directly against bare skin, and the neck should not be left exposed.

Question 8Hair Care and Hairdressing

What is the primary purpose of a patch test before applying a chemical relaxer or color?

  1. To predict an allergic reaction to the product Correct answer.
  2. To determine the final color result
  3. To set the processing time
  4. To measure the hair's tensile strength

Explanation

A patch test checks for an allergic or sensitized reaction by applying a small amount of product to the skin. It does not predict color outcome or set processing time.

Question 9Hair Care and Hairdressing

A client's hair feels rough and absorbs water very quickly. Which porosity condition does this most likely indicate?

  1. Resistant porosity
  2. Low porosity
  3. Normal porosity
  4. High porosity Correct answer.

Explanation

High porosity means the cuticle is raised or damaged, so hair takes in and loses moisture rapidly and feels rough. Low porosity resists moisture because the cuticle is tightly closed.

Question 10Hair Care and Hairdressing

A client with fine, limp hair wants more volume. Which styling approach best supports that goal?

  1. Apply heavy pomade at the roots
  2. Comb the hair flat while it dries
  3. Coat the hair with a rich oil before styling
  4. Use a light mousse and blow-dry with lift at the root Correct answer.

Explanation

Fine hair is easily weighed down, so lightweight products plus root lift during blow-drying add body without heaviness. Heavy products and flat drying reduce volume.

Question 11Hair Care and Hairdressing

What is the purpose of a strand test before a color service?

  1. To measure the client's hair length
  2. To sterilize the tools
  3. To determine how the hair will respond to the formula and timing Correct answer.
  4. To check the client's scalp for abrasions

Explanation

A strand test shows how the hair reacts to the chosen formula and processing time so adjustments can be made before the full application. Scalp checks and tool sanitation are separate steps.

Question 12Hair Care and Hairdressing

Which haircutting term describes cutting hair at the same length throughout with no elevation?

  1. Blunt cut Correct answer.
  2. Texturizing
  3. Layering
  4. Graduation

Explanation

A blunt cut is created with zero elevation so all hair falls to one length. Graduation builds weight lines, layering removes weight, and texturizing alters the ends.

Question 13Hair Care and Hairdressing

Why is it important to keep shears sharp and properly aligned?

  1. Sharp shears change the hair's natural color
  2. Dull shears cut faster and reduce service time
  3. Sharp shears add moisture to the hair
  4. Dull or misaligned shears crush and split the hair ends Correct answer.

Explanation

Sharp, aligned blades slice cleanly, while dull or misaligned shears crush and fray the ends, causing split ends and an uneven line. Shears do not affect moisture or color.

Question 14Hair Care and Hairdressing

A client wants a style that holds a smooth, rounded shape when brushed. Which blow-dryer attachment is designed for this?

  1. A diffuser
  2. A concentrator nozzle Correct answer.
  3. A vent brush
  4. A pik attachment

Explanation

A concentrator focuses airflow along the hair to smooth the cuticle and shape the ends. A diffuser spreads air for curl definition, and a pik lifts the roots.

Question 15Hair Care and Hairdressing

Which of the following best describes the role of a thermal protector during heat styling?

  1. It permanently straightens the hair
  2. It lightens the hair's natural pigment
  3. It forms a barrier that helps reduce heat damage Correct answer.
  4. It increases the iron's temperature

Explanation

Thermal protectors coat the hair to help buffer heat and reduce moisture loss during styling. They do not permanently alter shape, lighten pigment, or raise tool temperature.

Question 16Hair Care and Hairdressing

During a relaxer service, why is a protective base applied to the scalp?

  1. To neutralize the relaxer
  2. To add shine to the new growth
  3. To speed up the processing time
  4. To shield the scalp from irritation Correct answer.

Explanation

A protective base creates a barrier between the chemical and the skin to reduce irritation. It does not accelerate processing, add shine, or neutralize the product.

Question 17Hair Care and Hairdressing

What is the function of a neutralizing shampoo after a relaxer service?

  1. To restore the hair's pH and stop the relaxer action Correct answer.
  2. To soften the new growth further
  3. To add temporary color to the hair
  4. To increase the curl pattern

Explanation

A neutralizing shampoo lowers the hair's pH and halts the relaxer's chemical action. Without it, the relaxer could continue processing and damage the hair.

Question 18Hair Care and Hairdressing

Which tool is best suited for detangling wet, curly hair with minimal breakage?

  1. A wide-tooth comb Correct answer.
  2. A fine-tooth comb
  3. A bristle brush
  4. A rattail comb

Explanation

A wide-tooth comb separates curls gently while wet hair is fragile, reducing breakage. Fine-tooth and rattail combs pull through tangles, and bristle brushes are for smoothing.

Question 19Hair Care and Hairdressing

A client with a round face shape is choosing a haircut. Which principle should guide the design?

  1. Create length and vertical lines to slim the face Correct answer.
  2. Add width at the jawline to balance the cheeks
  3. Add volume at the sides to widen the face
  4. Cut the hair to one short length with no shape

Explanation

For a round face, length and vertical lines create the illusion of a narrower, longer face. Adding width at the sides or jawline emphasizes roundness.

Question 20Hair Care and Hairdressing

A client's hair is over-porous and fragile after repeated lightening. Which approach best supports the hair during a new color service?

  1. Perform a strand test and use a lower-volume developer with a conditioning treatment Correct answer.
  2. Apply the strongest lightener at full strength immediately
  3. Increase processing heat to shorten the time
  4. Shampoo with a high-pH clarifier right before coloring

Explanation

Compromised, over-porous hair needs gentler chemistry and conditioning support, so a strand test with lower-volume developer helps control the result. Aggressive lightening, clarifying, or added heat risks further damage.

Question 21Hair Care and Hairdressing

A stylist is cutting a graduated bob and wants weight to build toward the perimeter. Which elevation pattern achieves this?

  1. Slight to moderate elevation with the hair held out from the head Correct answer.
  2. High elevation of 90 degrees throughout
  3. Twist-cutting at the ends
  4. Zero elevation throughout

Explanation

Graduation uses slight to moderate elevation so shorter layers sit above a longer perimeter, building weight at the bottom. Zero elevation produces a blunt line and 90-degree elevation creates layers.

Question 22Hair Care and Hairdressing

A client's scalp shows flaking, redness, and itching. What is the appropriate professional response?

  1. Apply a strong exfoliant and continue the service
  2. Proceed with a relaxer to remove the flakes
  3. Diagnose the condition and treat it with a medicated shampoo
  4. Refer the client to a physician and avoid chemical services on the area Correct answer.

Explanation

Stylists are not licensed to diagnose or treat scalp disorders, so referral to a physician is appropriate and chemical services should be avoided on affected areas. Treating or proceeding could worsen the condition.

Question 23Hair Care and Hairdressing

How does the shape of the hair follicle influence the hair that grows from it?

  1. Follicle shape determines the hair's color only
  2. A curved follicle produces straight hair
  3. The follicle shape affects the curl pattern of the hair Correct answer.
  4. A straight follicle produces tightly curled hair

Explanation

The curvature of the follicle guides the shape of the hair shaft, so curved follicles produce curl and straight follicles produce straight hair. Color is determined by melanin, not follicle shape.

Question 24Hair Care and Hairdressing

A client with very long hair wants a trim that preserves length while removing split ends. Which technique is most appropriate?

  1. Cutting three inches off the perimeter
  2. Applying a relaxer to the ends
  3. Razor-cutting the entire length
  4. Dusting the ends with a small trim Correct answer.

Explanation

Dusting removes only the very ends, preserving length while clearing split tips. Large removals, razor-cutting, and chemicals do not address the goal of keeping length.

Question 25Hair Care and Hairdressing

Which of the following is the correct order for a basic shampoo and scalp massage service?

  1. Massage, towel dry, shampoo, condition
  2. Shampoo, rinse, condition, rinse, towel dry Correct answer.
  3. Condition, shampoo, towel dry, massage
  4. Condition, towel dry, massage, shampoo

Explanation

The service begins with shampoo and rinsing to cleanse, then conditioner is applied and rinsed, and the hair is towel dried. Conditioning before shampooing or drying before cleansing is out of order.

Question 26Hair Care and Hairdressing

Which phase of the hair growth cycle is the resting phase, after which the hair is shed?

  1. Anagen
  2. Keratin phase
  3. Telogen Correct answer.
  4. Catagen

Explanation

Telogen is the resting phase at the end of the growth cycle, lasting roughly three months before the club hair sheds. Anagen is active growth and catagen is the transitional phase, so telogen is the correct resting stage.

Question 27Hair Care and Hairdressing

Which layer of the hair shaft contains the pigment that determines natural hair color?

  1. Follicle
  2. Cuticle
  3. Cortex Correct answer.
  4. Medulla

Explanation

Melanin pigment is deposited in the cortex, the thick middle layer where color and much of the hair's strength reside. The cuticle is the protective outer layer and the medulla is the innermost core.

Question 28Hair Care and Hairdressing

Which hair type is naturally the most resistant to chemical processing?

  1. Coarse, low-porosity hair Correct answer.
  2. Medium, wavy hair
  3. Fine, porous hair
  4. Chemically lightened hair

Explanation

Coarse hair with a tightly layered cuticle resists penetration, so chemicals act more slowly on it. Fine or porous hair takes up chemicals faster because its cuticle is more open.

Question 29Hair Care and Hairdressing

Which of the following describes the correct way to section hair before a wet cut?

  1. Gather all the hair into a single ponytail at the crown
  2. Comb all the hair forward over the face
  3. Divide the hair into four equal sections using a center part and a part from ear to ear Correct answer.
  4. Part the hair only at the front hairline

Explanation

A four-section parting through the center of the head and ear to ear gives balanced, manageable working areas. This standard sectioning keeps the cut symmetrical and lets each subsection be controlled.

Question 30Hair Care and Hairdressing

What is the main function of conditioner applied after shampooing?

  1. To lighten the natural hair color
  2. To lift the cuticle and remove residue
  3. To permanently change the hair's curl pattern
  4. To smooth the cuticle and improve manageability Correct answer.

Explanation

Conditioners deposit on the hair and help smooth the cuticle, which reduces friction and improves combability. They do not permanently alter curl or color.

Question 31Hair Care and Hairdressing

Which of the following is a guideline for safely using a curling iron?

  1. Hold the iron in one spot until the hair begins to smoke
  2. Wrap the hair tightly while it is still soaking wet
  3. Use the highest heat setting on every client
  4. Test the iron temperature on a strand before styling the whole head Correct answer.

Explanation

A strand test confirms the iron is not too hot for that client's hair before the whole head is exposed. This protects against heat damage and gives a predictable result.

Question 32Hair Care and Hairdressing

What does hair elasticity describe?

  1. The amount of sebum on the scalp
  2. The diameter of an individual strand
  3. The hair's natural curl pattern
  4. The hair's ability to stretch and return to its original length Correct answer.

Explanation

Elasticity is the ability of wet hair to stretch and spring back, which reflects the strength of the cortex. Hair that stretches well and returns is generally healthy and strong.

Question 33Hair Care and Hairdressing

A client's hair is naturally level 7 and the goal is a level 5 result. Which color formulation approach is most appropriate?

  1. Apply a level 5 color with an appropriate developer to deposit darker tone Correct answer.
  2. Apply a lightener first, then a level 5 color
  3. Apply a level 9 color to lift before going darker
  4. Apply a level 7 color to preserve the current depth

Explanation

When the target is darker than the natural level, a deposit-only color at the target level achieves the result without unnecessary lift. Lifting first would be counterproductive when going darker.

Question 34Hair Care and Hairdressing

A client with resistant gray hair wants full coverage. Which approach best supports the goal?

  1. Apply color to dry hair only at the ends
  2. Skip the developer and apply color straight from the tube
  3. Use a permanent color formulated for gray coverage with adequate processing time Correct answer.
  4. Use a demi-permanent color with a low-volume developer

Explanation

Resistant gray often needs a permanent color designed for coverage and full processing time to open the cuticle and deposit pigment. Demi-permanent color alone may not fully cover resistant gray.

Question 35Hair Care and Hairdressing

What is the purpose of backcombing (teasing) in a finished style?

  1. To smooth the cuticle for a glossy finish
  2. To add volume and support at the base of the hair Correct answer.
  3. To shorten the hair's overall length
  4. To remove tangles before shampooing

Explanation

Backcombing builds a cushion of hair at the scalp that supports the shape and adds volume. It is a styling technique used for lift, not for detangling or smoothing.

Question 36Hair Care and Hairdressing

A client with an oval face and a prominent forehead asks for a fringe. Which design choice is most flattering?

  1. A heavy, blunt fringe cut straight across at the brow
  2. A soft, side-swept fringe with graduated length Correct answer.
  3. No fringe, with all hair pulled tightly back
  4. A fringe cut very short above the hairline

Explanation

A soft side-swept fringe breaks up the forehead line and adds balance without a harsh horizontal line. Graduated length softens the face rather than emphasizing the forehead.

Question 37Hair Care and Hairdressing

Which cutting technique creates a soft, blended edge by cutting into the ends with the shear tips?

  1. Razor rotation
  2. Clubbing
  3. Blunt cutting
  4. Point cutting Correct answer.

Explanation

Point cutting uses the tips of the shears to snip into the ends, softening the perimeter and blending layers. Blunt cutting produces a solid, straight line instead.

Question 38Hair Care and Hairdressing

A client wants a layered cut with movement but has fine hair. Which elevation choice best supports volume?

  1. Cut the hair dry with no elevation
  2. Use higher elevation in the crown area to build lift Correct answer.
  3. Cut all layers at the same low elevation
  4. Cut everything at zero elevation

Explanation

Higher elevation creates shorter layers that stack and support volume, which is especially useful for fine hair. Low or zero elevation keeps weight at the perimeter and reduces lift.

Question 39Hair Care and Hairdressing

Which of the following is the appropriate first step when a client requests a relaxer and has a scalp abrasion?

  1. Postpone the service until the scalp has healed Correct answer.
  2. Apply a stronger relaxer to shorten contact time
  3. Apply the relaxer quickly to finish before irritation begins
  4. Proceed but skip the neutralizing shampoo

Explanation

Chemical relaxers are strong alkaline products that can severely irritate broken skin, so an abrasion is a contraindication. The safe response is to postpone until the scalp is intact.

Question 40Hair Care and Hairdressing

What does the term 'base control' refer to when wrapping a perm?

  1. The size of the perm rod selected
  2. The temperature of the processing room
  3. The position of the tool relative to its base section Correct answer.
  4. The amount of neutralizing solution used

Explanation

Base control describes where the rod sits in relation to the base of its subsection, such as on-base, half-off-base, or off-base. It influences the volume and direction of the resulting curl.

Question 41Hair Care and Hairdressing

A client with oily scalp and dry ends should receive which shampooing approach?

  1. No shampoo, only conditioner
  2. A mild shampoo concentrated at the scalp with conditioner on the ends Correct answer.
  3. A medicated shampoo left on for the full service
  4. A strong clarifying shampoo over the entire length

Explanation

Oily scalp and dry ends call for balancing: cleanse where oil accumulates and condition where moisture is needed. Strong clarifying over the whole length would further dry the ends.

Question 42Hair Care and Hairdressing

Which styling product is best for adding firm hold and shine when finishing a sleek updo?

  1. Styling gel Correct answer.
  2. Leave-in conditioner
  3. Thermal spray
  4. Light mousse

Explanation

Gel provides firm hold and a glossy finish that keeps an updo's shape in place. Mousse is lighter and thermal spray is intended for heat protection rather than firm hold.

Question 43Hair Care and Hairdressing

A client's hair is level 6 with warm undertones and the goal is a cool level 6. Which color correction principle applies?

  1. Use a blue or ash-based toner to neutralize unwanted warmth Correct answer.
  2. Add more warmth to intensify the natural tone
  3. Lighten two levels to remove the warmth
  4. Apply a clear gloss only

Explanation

Cool tones are neutralized by their opposite on the color wheel, so blue or ash-based products counteract unwanted warmth. Adding warmth would intensify the problem rather than correct it.

Question 44Hair Care and Hairdressing

A client with tightly coiled hair reports breakage along the hairline after years of tight braiding. What is the most likely cause?

  1. Excess sebum production
  2. A normal shedding cycle
  3. Seborrheic dermatitis
  4. Traction alopecia from sustained tension Correct answer.

Explanation

Repeated tight styling pulls on the follicle and can cause traction alopecia, often seen along the hairline. Reducing tension and varying styles helps prevent further loss.

Question 45Hair Care and Hairdressing

What distinguishes a demi-permanent color from a permanent color?

  1. Demi-permanent color requires no developer
  2. Demi-permanent color lifts natural pigment significantly
  3. Demi-permanent color permanently alters the cortex
  4. Demi-permanent color deposits tone without lifting natural pigment Correct answer.

Explanation

Demi-permanent color deposits pigment and fades gradually over shampoos without lifting the natural pigment. Permanent color uses higher-volume developer to lift and deposit simultaneously.

Question 46Hair Care and Hairdressing

A client's hair snaps almost immediately when stretched wet. What does this indicate and how should the service be adjusted?

  1. Low elasticity; avoid chemical services and recommend conditioning treatments Correct answer.
  2. High porosity; apply lightener immediately
  3. Normal elasticity; proceed as planned
  4. High elasticity; proceed with a strong chemical service

Explanation

Wet hair that breaks with little stretch has low elasticity, meaning the cortex is weak and cannot tolerate further chemical stress. Conditioning and gentle care should come before any chemical service.

Question 47Hair Care and Hairdressing

A client with medium texture wants a graduated bob, but the nape hair is much denser than the sides. What cutting adjustment best balances the shape?

  1. Use slightly lower elevation at the nape to reduce excess weight Correct answer.
  2. Skip the nape section entirely
  3. Cut the nape at the same elevation as the sides
  4. Cut the nape shorter to create more volume

Explanation

Denser areas build more weight, so lowering elevation there removes bulk and helps the perimeter read evenly. Uniform elevation would leave the nape heavier than the sides.

Question 48Hair Care and Hairdressing

A client with fine, lightened hair wants a perm. Which analysis best guides the recommendation?

  1. Decline the perm because lightened fine hair is too fragile for the reduction process Correct answer.
  2. Proceed because fine hair takes a perm quickly
  3. Proceed but skip the neutralizer to save time
  4. Proceed using a stronger solution to ensure a lasting curl

Explanation

Lightened fine hair has compromised disulfide bonds and a weakened cortex, so a reducing perm solution risks severe breakage. The professional choice is to decline or postpone and recommend strengthening care.

Question 49Hair Care and Hairdressing

A stylist notices that a client's color fades rapidly and the cuticle feels rough. Which explanation is most consistent with these findings?

  1. The hair is in the anagen phase
  2. The hair has high porosity and releases pigment and moisture easily Correct answer.
  3. The hair has low porosity and resists moisture
  4. The hair has strong elasticity

Explanation

A rough, open cuticle lets moisture and color molecules escape, which is characteristic of high porosity and explains the rapid fading. Low porosity hair holds onto both moisture and pigment.

Question 50Hair Care and Hairdressing

A client with medium-density, straight hair wants a blunt one-length cut at the collarbone. Which cutting position and tension best support a clean, even perimeter line?

  1. Cut the hair in vertical sections with the hair elevated 90 degrees from the scalp
  2. Cut the hair with the head tilted back using light tension and point-cutting at the ends
  3. Cut the hair in horizontal sections with the head tilted forward and minimal tension
  4. Cut the hair with the head upright using consistent, even tension and zero elevation Correct answer.

Explanation

A blunt perimeter is built by cutting at zero elevation with the head in its natural upright position, so gravity and the tension of the comb hold match on both sides. Consistent, even tension ensures the guideline is transferred accurately around the head. Tilting the head or varying elevation changes the length relationship and distorts the line.
