Question 1Hair Care and Haircutting

Which layer of the hair shaft forms the tough, outer protective covering?

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

Explanation

The cuticle is the outermost layer of the hair shaft and is made of overlapping, scale-like cells that shield the inner structures from damage. Layers beneath it include the cortex, which provides strength and holds pigment, and the medulla, the innermost core.

Question 2Hair Care and Haircutting

Natural hair color is determined by melanin located in which part of the hair?

  1. Root sheath
  2. Cuticle
  3. Cortex Correct answer.
  4. Medulla

Explanation

Melanin granules are deposited in the cortex, the thick middle layer of the hair shaft, which is why coloring and lightening services must reach the cortex to change hair color. The cuticle is colorless and the medulla does not carry pigment.

Question 3Hair Care and Haircutting

Which phase of the hair growth cycle is the active growing phase?

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

Explanation

Anagen is the growth phase, lasting roughly two to six years, during which new cells form and the hair lengthens. Catagen is the transitional phase, and telogen is the resting phase that ends with shedding.

Question 4Hair Care and Haircutting

A client's hair absorbs water and color quickly but feels dry and rough. This indicates hair with:

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

Explanation

Highly porous hair has a raised cuticle that lets moisture and color enter quickly but also allows it to escape, leaving the hair dry and rough. Low-porosity hair resists absorption, and normal-porosity hair takes in and retains moisture evenly.

Question 5Hair Care and Haircutting

The average rate of hair growth on a healthy scalp is approximately:

  1. 2 inches per month
  2. 1 inch per week
  3. 1/8 inch per month
  4. 1/2 inch per month Correct answer.

Explanation

Scalp hair grows about one-half inch per month, or roughly six inches per year, which is why color touch-ups and trims are usually scheduled about four to six weeks apart.

Question 6Hair Care and Haircutting

When a stylist wets a strand and gently stretches it, normal elasticity allows the hair to stretch about what percentage of its length and return?

  1. 5 percent
  2. 100 percent
  3. 200 percent
  4. 50 percent Correct answer.

Explanation

Hair with normal elasticity stretches up to about half its original length when wet and returns to its former shape without breaking. Hair that snaps before stretching that far has low elasticity and should be treated gently.

Question 7Hair Care and Haircutting

A blunt, one-length cut is created by holding the hair at what elevation?

  1. 0 degrees Correct answer.
  2. 180 degrees
  3. 90 degrees
  4. 45 degrees

Explanation

At zero degrees the hair hangs in its natural fall and every subsection is cut along the same line, producing a solid, one-length perimeter. Higher elevations build layers or graduation.

Question 8Hair Care and Haircutting

A graduated haircut is built by cutting each subsection at approximately:

  1. 180 degrees
  2. 90 degrees
  3. 45 degrees Correct answer.
  4. 0 degrees

Explanation

Graduation is created at about forty-five degrees, where each subsection is held out from the head and cut slightly shorter than the one below it, building a stacked effect. Zero degrees gives a solid line and ninety degrees gives uniform layers.

Question 9Hair Care and Haircutting

A guide that is moved from subsection to subsection as the cut progresses is called a:

  1. Traveling guide Correct answer.
  2. Perimeter guide
  3. Stationary guide
  4. Reference part

Explanation

A traveling (moving) guide is taken from the section just cut and carried forward into the next subsection, so the shape develops along with the cut. A stationary guide stays in one place and all other sections are cut to it.

Question 10Hair Care and Haircutting

Why does a stylist cross-check a finished haircut?

  1. To create a new guideline
  2. To check the balance Correct answer.
  3. To soften the cut ends
  4. To remove interior bulk

Explanation

Cross-checking means taking sections in the opposite direction from the original cutting pattern to confirm the two sides match and the shape is balanced. It reveals uneven areas before the client leaves the chair.

Question 11Hair Care and Haircutting

Thinning shears are used mainly to:

  1. Shorten the overall length
  2. Reduce bulk without changing length Correct answer.
  3. Create a blunt perimeter
  4. Build a graduated shape

Explanation

Thinning shears have one cutting blade and one comb blade, so they remove a portion of the hair within a section and reduce bulk while leaving the overall length intact. They are not a length-cutting tool.

Question 12Hair Care and Haircutting

Razor cutting works best when the hair is:

  1. Dry and curly
  2. Dry and coarse
  3. Wet and conditioned Correct answer.
  4. Dry and straight

Explanation

A razor glides and softens ends best on wet hair that has conditioner or a cutting lotion applied for slip, which prevents dragging and reduces the risk of cutting the client. Dry hair causes the razor to pull and skip.

Question 13Hair Care and Haircutting

Point cutting is done by holding the shears:

  1. Parallel to the strand
  2. Open and sliding down
  3. Perpendicular to the ends Correct answer.
  4. Flat against the scalp

Explanation

In point cutting the tips of the shears point into the ends of a section, usually at a slight angle, to notch the ends and soften the line. The blades do not slide down the strand and are never placed flat on the scalp.

Question 14Hair Care and Haircutting

Which technique requires the shears to be partially opened and slid down the strand to soften and blend the ends?

  1. Slide cutting Correct answer.
  2. Blunt cutting
  3. Clipper-over-comb
  4. Notching

Explanation

Slide cutting uses partially opened shears that are closed gently while sliding down the strand, removing weight and blending the ends into the shape. It is performed on wet, conditioned hair for control.

Question 15Hair Care and Haircutting

When performing clipper-over-comb, the comb should be held:

  1. At a 45-degree angle away from the head
  2. Flat against the head Correct answer.
  3. Parallel to the hair strand
  4. Perpendicular to the head

Explanation

In clipper-over-comb the comb is held flat against the head and the clippers follow the comb's surface, so the comb controls the length and the cut stays close to the head. Angling the comb away produces an uneven result.

Question 16Hair Care and Haircutting

A stylist finds the haircut is shorter on one side after cutting fine hair. The most likely cause is:

  1. Dull shears
  2. Cutting the hair dry
  3. Tension stretched the hair Correct answer.
  4. Sections cut too small

Explanation

Fine hair is easily stretched, and cutting it under heavy tension lets it spring back shorter once released, producing an uneven line. Tension should be light and consistent from section to section.

Question 17Hair Care and Haircutting

For a client with very thick, dense hair, subsectioning should be:

  1. Wider than for thin hair
  2. The same as for thin hair
  3. Done only at the perimeter
  4. Narrower than for thin hair Correct answer.

Explanation

Dense hair holds more strands per square inch, so each subsection must be thinner and narrower to be held cleanly and cut accurately. Oversized subsections in thick hair cause the shears to push the hair rather than cut it.

Question 18Hair Care and Haircutting

Cutting the hair at an angle other than its natural fall is called:

  1. Vertical distribution
  2. Shifted distribution Correct answer.
  3. Uniform distribution
  4. Natural distribution

Explanation

In shifted (overdirected) distribution the hair is moved away from its natural fall before cutting, which builds length or weight toward the opposite side. Natural distribution leaves the hair exactly where it grows.

Question 19Hair Care and Haircutting

A tapered nape is created by:

  1. Cutting the nape hair to one uniform length
  2. Gradually shortening the hair toward the neckline Correct answer.
  3. Leaving the nape hair longer than the crown
  4. Cutting the nape hair with a razor only

Explanation

A tapered nape follows the contour of the head and neckline by getting progressively shorter as it approaches the hairline, usually with clippers or clipper-over-comb work. A squared or rounded nape keeps the length more consistent.

Question 20Hair Care and Haircutting

Which technique creates a visibly chunky, uneven edge on the ends?

  1. Slithering
  2. Notching Correct answer.
  3. Blunt cutting
  4. Slicing

Explanation

Notching removes small V-shaped pieces along the ends with the shear tips, producing a chunkier, more separated edge with a stronger texturized effect. Slithering and slicing blend and soften rather than create visible chunks.

Question 21Hair Care and Haircutting

Which brush type is best for distributing natural oils from the scalp through the hair?

  1. Wide-tooth comb
  2. Boar-bristle brush Correct answer.
  3. Vent brush
  4. Round thermal brush

Explanation

Natural boar bristles carry sebum away from the scalp and spread it along the hair shaft, adding shine and conditioning. Vent and thermal brushes are designed for drying and styling rather than oil distribution.

Question 22Hair Care and Haircutting

A client with an oily scalp and fine hair should be shampooed with:

  1. A heavy cream shampoo
  2. A color-depositing shampoo
  3. A moisturizing shampoo
  4. A clarifying shampoo Correct answer.

Explanation

Clarifying shampoos remove excess oil and product buildup without adding weight, which suits an oily scalp and fine hair. Heavy and moisturizing formulas add emollients that can make fine hair limp.

Question 23Hair Care and Haircutting

Scalp massage should be avoided when the client has:

  1. Fine hair
  2. Oily hair
  3. Dry hair
  4. An abrasion or open lesion on the scalp Correct answer.

Explanation

Massage is contraindicated over broken skin, abrasions, or contagious conditions because it can spread infection and irritate the area. Hair and scalp type alone do not prohibit massage.

Question 24Hair Care and Haircutting

A protein conditioner is most appropriate for hair that is:

  1. Fine and limp
  2. Chemically damaged and porous Correct answer.
  3. Oily at the scalp
  4. Curly and dry at the ends

Explanation

Protein conditioners temporarily patch gaps in chemically damaged, porous hair, improving strength and feel. They are not a solution for oiliness or limpness, where lighter formulas are preferred.

Question 25Hair Care and Haircutting

Which hair analysis finding most strongly suggests that a razor cut should be avoided?

  1. Medium, wavy hair
  2. Fine, fragile hair Correct answer.
  3. Coarse, straight hair
  4. Thick, curly hair

Explanation

A razor removes weight by cutting at an angle along the strand, which can fray and break fragile, fine hair with limited strength. Coarser hair withstands the razor because each strand has more mass.

Question 26Hair Care and Haircutting

Hair density is best described as the:

  1. ability of the hair to absorb moisture
  2. direction in which the hair leaves the follicle
  3. number of hairs per square inch of scalp Correct answer.
  4. diameter of a single strand of hair

Explanation

Density is a count of how many hairs grow in a given area of scalp, usually stated per square inch. Diameter describes texture, moisture uptake describes porosity, and growth direction describes the growth pattern or stream.

Question 27Hair Care and Haircutting

The main purpose of shampooing is to:

  1. seal the cuticle so that it lies flat after styling
  2. replace natural oils that were lost during styling
  3. cleanse away dirt, oil, and product buildup Correct answer.
  4. deposit color pigment deep into the cortex

Explanation

Shampoo contains surfactants that lift and rinse away sebum, perspiration, environmental soil, and styling residue from the hair and scalp. Conditioning products, not shampoo, are what restore oils and smooth the cuticle.

Question 28Hair Care and Haircutting

Hair that takes in moisture quickly, dries quickly, and has a raised cuticle is classified as:

  1. normal elasticity
  2. high porosity Correct answer.
  3. low porosity
  4. fine texture

Explanation

High porosity means the cuticle layer is open or damaged, so water enters and leaves the shaft rapidly. Low porosity is the opposite, and elasticity and texture describe different properties entirely.

Question 29Hair Care and Haircutting

When holding haircutting shears properly, the thumb is placed in the:

  1. pivot screw
  2. stationary blade ring
  3. moving blade ring Correct answer.
  4. finger rest

Explanation

The thumb sits in the smaller moving-blade ring and drives the blade, while the ring finger rests in the larger stationary ring. The little finger rests on the finger rest for balance.

Question 30Hair Care and Haircutting

When cutting hair with strong curl or wave, the stylist should:

  1. stretch each subsection tightly before cutting
  2. cut each subsection slightly longer on the right side
  3. cut the hair only when it is soaking wet
  4. work with minimal tension and allow for shrinkage Correct answer.

Explanation

Curly hair is cut with little or no tension because the curl contracts as it dries, and stretching the strand causes the finished shape to be too short. The stylist accounts for this shrinkage when judging length.

Question 31Hair Care and Haircutting

Cutting all of the hair at a 90-degree elevation produces:

  1. a long-layered shape with shorter top layers
  2. a blunt, one-length perimeter
  3. uniform layers throughout the shape Correct answer.
  4. a graduated shape with stacked ends

Explanation

At 90 degrees the hair is projected perpendicular to the head, so each section falls to the same level and forms uniform layers. Lower elevations build weight, while higher elevations create longer layers.

Question 32Hair Care and Haircutting

Curly hair is usually cut in its natural dry state because:

  1. the finished shape can be judged as it is cut Correct answer.
  2. dry cutting prevents split ends from forming
  3. wet hair cannot be combed into a guide line
  4. dry hair is easier to subsection precisely

Explanation

Cutting curls dry lets the stylist see the actual spring factor and silhouette the client will wear. Wet cutting of curly hair conceals the shrinkage that changes the final outline.

Question 33Hair Care and Haircutting

The best shampoo choice for a client with color-treated hair is one that is:

  1. clarifying
  2. high-alkaline
  3. medicated
  4. sulfate-free Correct answer.

Explanation

Sulfate-free formulas clean gently and are less likely to strip or fade deposited color. Clarifying and high-alkaline shampoos open the cuticle and accelerate color loss.

Question 34Hair Care and Haircutting

During a scalp analysis, a stylist observes redness, swelling, and open sores. The appropriate action is to:

  1. refer the client to a physician Correct answer.
  2. massage the area to increase circulation
  3. apply a scalp astringent and proceed
  4. shampoo with a medicated shampoo

Explanation

Signs of inflammation with broken skin are outside the scope of cosmetology services and require medical evaluation. Services are withheld until a physician clears the client.

Question 35Hair Care and Haircutting

The best way to maintain control while cutting long, dense hair is to:

  1. hold the hair taut with the comb only
  2. cut the entire perimeter in one pass
  3. thin the interior before cutting the perimeter
  4. work in uniform subsections Correct answer.

Explanation

Dividing the head into numbered, uniform subsections keeps the guide visible and prevents unwanted length shifts. Working in one pass or relying on the comb alone sacrifices accuracy.

Question 36Hair Care and Haircutting

A moisturizing conditioner is most appropriate for hair that is:

  1. oily at the scalp
  2. freshly lightened and firm
  3. fine and limp
  4. dry and coarse Correct answer.

Explanation

Moisturizing conditioners add emollients and humectants that soften dry, coarse hair and improve manageability. Hair that is limp or oily needs lightweight or volumizing formulas instead.

Question 37Hair Care and Haircutting

A paddle brush is most useful for:

  1. backcombing the crown for height
  2. lifting hair at the root for volume
  3. applying product to the scalp
  4. detangling and smoothing long hair Correct answer.

Explanation

The wide, flat cushion of a paddle brush glides through lengths to remove tangles and create a smooth finish. Root lift and backcombing depend on round or narrow styling brushes.

Question 38Hair Care and Haircutting

A client has a strong cowlick at the front hairline. The best approach is to:

  1. remove the cowlick with a razor at the scalp
  2. cut the cowlick against the growth pattern at 90 degrees
  3. cut the area shorter to force the hair to lie flat
  4. cut with the growth pattern and leave extra length Correct answer.

Explanation

Hair in a cowlick grows away from the rest of the strand pattern, so cutting it shorter exposes the swirl and creates a gap. Leaving extra length and working with the direction of growth lets the hair blend into the finished style.

Question 39Hair Care and Haircutting

In a wet stretch test, a strand stretches and does not return to its original length. This indicates the hair:

  1. lacks protein and has been overprocessed Correct answer.
  2. has normal elasticity and is ready for service
  3. has low porosity and resists moisture
  4. is strong and can be lightened safely

Explanation

Hair that remains elongated after stretching has lost internal protein structure, typical of overprocessing. It must be treated gently and rebuilt before any further chemical service.

Question 40Hair Care and Haircutting

To keep a perimeter line level and symmetrical, the stylist should cut with the client's head:

  1. turned slightly toward the working side
  2. tilted forward to relax the nape
  3. resting on the shampoo bowl
  4. in its natural, upright position Correct answer.

Explanation

A level perimeter is judged against natural fall, so the head must stay upright and balanced while cutting. Tilting or turning the head shifts the hair's fall and produces an uneven line.

Question 41Chemical Services (Color, Texture, Relaxing)

Which developer strength is used to deposit permanent color without lifting the natural pigment?

  1. 30 volume
  2. 20 volume
  3. 10 volume Correct answer.
  4. 40 volume

Explanation

Developer strength controls the amount of lift. Ten-volume peroxide is a deposit-only strength, while 20, 30, and 40 volume lift one, two to three, and three to four levels respectively.

Question 42Chemical Services (Color, Texture, Relaxing)

Which ingredient is the active chemical in a lye relaxer?

  1. Hydrogen peroxide
  2. Guanidine hydroxide
  3. Sodium hydroxide Correct answer.
  4. Ammonium thioglycolate

Explanation

Lye relaxers are formulated with sodium hydroxide, a strong alkali that straightens by breaking the disulfide bonds in the hair. Ammonium thioglycolate is a waving lotion ingredient, not a relaxer base.

Question 43Chemical Services (Color, Texture, Relaxing)

How long before a color service should a patch test be performed?

  1. 24 to 48 hours Correct answer.
  2. 1 hour
  3. 5 minutes
  4. 7 days

Explanation

A patch test is applied 24 to 48 hours before the service so that a delayed allergic reaction has time to appear. A reaction that develops after the service has started cannot be anticipated any other way.

Question 44Chemical Services (Color, Texture, Relaxing)

Which chemical is the active ingredient in most alkaline permanent waves?

  1. Sodium hydroxide
  2. Hydrogen peroxide
  3. Guanidine hydroxide
  4. Ammonium thioglycolate Correct answer.

Explanation

Alkaline waves use ammonium thioglycolate as the reducing agent, which breaks disulfide bonds so the hair can be reshaped around a rod. The neutralizer later rebuilds those bonds.

Question 45Chemical Services (Color, Texture, Relaxing)

A hair lightener differs from permanent color because a lightener:

  1. requires no developer to activate
  2. works only on previously tinted hair
  3. deposits color while it lifts pigment
  4. lifts natural pigment and cannot deposit color Correct answer.

Explanation

Lighteners contain persulfates and peroxide that diffuse natural pigment out of the cortex; they add no artificial tone. Permanent color both lifts and deposits because it contains dye intermediates along with developer.

Question 46Chemical Services (Color, Texture, Relaxing)

When applying permanent color to virgin hair, the product is applied first to the:

  1. the entire length at once
  2. midlengths and ends Correct answer.
  3. the nape only
  4. scalp area

Explanation

The scalp holds body heat, which speeds up the color reaction, so the scalp area is applied last. Midlengths and ends go first because they are further from the scalp and process more slowly.

Question 47Chemical Services (Color, Texture, Relaxing)

Which color neutralizes unwanted orange tones in the hair?

  1. Violet
  2. Yellow
  3. Blue Correct answer.
  4. Green

Explanation

Neutralizing colors sit opposite the unwanted tone on the color wheel. Blue is directly opposite orange, so a blue-based formula cancels orange cast.

Question 48Chemical Services (Color, Texture, Relaxing)

During a relaxer retouch, the product is applied to the:

  1. new growth at the scalp Correct answer.
  2. midlengths of the hair
  3. previously relaxed ends
  4. entire hair strand

Explanation

Retouch application places relaxer only on the new growth, because already relaxed hair has no disulfide bonds left to break. Overlapping onto relaxed hair causes overprocessing and breakage.

Question 49Chemical Services (Color, Texture, Relaxing)

A color line specifies a 1:1 mixing ratio. How much developer should be mixed with 2 ounces of color?

  1. 2 ounces Correct answer.
  2. 1 ounce
  3. 4 ounces
  4. 3 ounces

Explanation

A 1:1 ratio means equal parts of each component, so 2 ounces of color takes 2 ounces of developer. Measuring by weight or volume consistently keeps the formula predictable.

Question 50Chemical Services (Color, Texture, Relaxing)

After a sodium hydroxide relaxer is rinsed, neutralizing shampoo is worked through the hair until the lather:

  1. stays white and creamy Correct answer.
  2. becomes thin and watery
  3. turns pink
  4. turns green

Explanation

Neutralizing shampoo restores the hair's acid balance and removes residual alkali. Lathering is repeated until the shampoo stays white and creamy, which shows that no relaxer residue remains.
