Question 1Hair Care and Haircutting

A client requests a blunt one-length cut. Which cutting line should the stylist use to keep the perimeter solid and unlayered?

  1. A horizontal line at the crown Correct answer.
  2. A vertical line at the nape
  3. A traveling guideline
  4. A diagonal forward line

Explanation

A blunt one-length perimeter is built on a horizontal cutting line so each subsection is cut parallel to the floor and the lengths stack evenly. Diagonal and vertical lines remove weight and create graduation or layering, which breaks the solid perimeter.

Question 2Hair Care and Haircutting

Which tool is designed to thin bulk and blend weight without shortening the overall length of a section?

  1. Straight shears
  2. Thinning shears Correct answer.
  3. Razor
  4. Clippers

Explanation

Thinning shears have one straight blade and one notched blade, so they remove a percentage of hair within a section while leaving the longest strands intact. Straight shears cut every hair at the guide, and a razor slices length as well as softens.

Question 3Hair Care and Haircutting

When performing a blunt cut, at what angle should the fingers and shears be held relative to the subsection to preserve the guideline?

  1. At 45 degrees
  2. At 180 degrees
  3. Parallel to the subsection Correct answer.
  4. At 90 degrees

Explanation

Holding the fingers parallel to the subsection keeps the cut edge aligned with the established guideline, producing a clean blunt line. Angling the shears opens the line and creates graduation or unwanted texture.

Question 4Hair Care and Haircutting

A stylist wants to check balance and symmetry before finishing a haircut. Which technique is most appropriate?

  1. Cross-checking the sections from the opposite side Correct answer.
  2. Backcombing the crown
  3. Blow-drying with a round brush
  4. Applying a leave-in serum

Explanation

Cross-checking means taking sections in the opposite direction from the original cutting pattern so any unevenness becomes visible. It is a verification step, not a styling step, and it catches imbalance before the client leaves the chair.

Question 5Hair Care and Haircutting

Which term describes the natural point at which hair hangs from the scalp and where the hairline meets the forehead?

  1. Occipital bone Correct answer.
  2. Parietal ridge
  3. Nape
  4. Apex

Explanation

The occipital bone is the reference landmark at the back of the skull that guides elevation and sectioning in many cuts. The apex is the highest point of the head, the nape is the lower back hairline, and the parietal ridge is the widest curve of the skull.

Question 6Hair Care and Haircutting

A client with fine, straight hair wants a cut that adds fullness. Which cutting choice supports that goal?

  1. A one-length cut with a traveling guideline
  2. A razor cut with deep texturizing
  3. A long, heavily layered cut
  4. A blunt cut with minimal layering Correct answer.

Explanation

Blunt cutting keeps the ends solid, which makes fine hair appear denser because the perimeter is full. Heavy layering and razor texturizing remove weight and can make fine hair look thinner and stringy.

Question 7Hair Care and Haircutting

Which elevation produces a graduated shape in which each subsection is cut shorter than the one above it?

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

Explanation

Cutting at 45 degrees stacks each subsection above the previous one, so the perimeter is shorter and the shape builds weight toward the nape. Zero degrees is a blunt line, 90 degrees is uniform layering, and 180 degrees is long layering.

Question 8Hair Care and Haircutting

Which term describes the guideline that is established first and then followed by all subsequent subsections in a haircut?

  1. Stationary guideline Correct answer.
  2. Interior guideline
  3. Traveling guideline
  4. Cross guideline

Explanation

A stationary guideline stays in place while each subsection is cut to match it, which keeps the shape consistent. A traveling guideline moves with the cut and is used for continuous lengths such as a one-length perimeter.

Question 9Hair Care and Haircutting

A stylist is cutting a bob and wants weight to build toward the nape. Which combination supports that result?

  1. Horizontal line and 0-degree elevation
  2. Diagonal back line and 45-degree elevation Correct answer.
  3. Vertical line and 180-degree elevation
  4. Diagonal forward line and 90-degree elevation

Explanation

A diagonal back line with 45-degree elevation stacks subsections so length decreases toward the nape, building weight into a graduated bob. Horizontal lines at zero elevation give a blunt perimeter, and vertical lines at high elevation remove weight.

Question 10Hair Care and Haircutting

During a consultation, a client says her hair has been relaxed and she wants a short, layered cut. Which precaution should the stylist take?

  1. Cut the hair wet and use a razor for texture
  2. Apply a relaxer touch-up before cutting
  3. Assess elasticity and avoid over-thinning the chemically treated hair Correct answer.
  4. Use clippers for the entire cut

Explanation

Chemically treated hair can have reduced elasticity and may break under aggressive texturizing, so the stylist should assess the hair's condition and limit thinning. Cutting relaxed hair wet with a razor or applying more chemicals increases the risk of breakage.

Question 11Hair Care and Haircutting

A stylist notices a cowlick at the front hairline. What is the best approach when cutting that area?

  1. Cut it with a razor to soften the pattern
  2. Cut the cowlick shorter to force it down
  3. Ignore the area and cut the rest of the fringe
  4. Cut it longer and leave extra length to accommodate the growth pattern Correct answer.

Explanation

A cowlick grows in a different direction and can lift or part the fringe, so leaving extra length helps the hair lie with the pattern. Cutting it shorter or razoring it exaggerates the lift and creates an uneven fringe.

Question 12Hair Care and Haircutting

Which statement best explains why a stylist should not cut a client's hair completely dry when the goal is a precise one-length line?

  1. Dry hair is always more elastic than wet hair
  2. Wet hair stretches, so the line can shrink as it dries Correct answer.
  3. Wet hair is more difficult to comb
  4. Dry hair cannot be sectioned

Explanation

Wet hair elongates under tension, so a line cut wet can appear shorter or uneven once the hair dries and returns to its natural length. Dry cutting is useful for some textures, but for a precise one-length perimeter the stylist must account for shrinkage.

Question 13Hair Care and Haircutting

A stylist uses a razor to create soft texture on a client with coarse, curly hair. Which result is most likely if the razor is used aggressively?

  1. A tighter, more defined curl
  2. A smoother, more controlled curl pattern
  3. Longer-lasting curl retention
  4. Frayed ends and increased frizz Correct answer.

Explanation

A razor slices the cuticle and creates tapered, irregular ends that can fray and frizz on coarse, curly hair. Curly textures are better texturized with point cutting or slide cutting to preserve the curl pattern.

Question 14Hair Care and Haircutting

Which technique is used to soften a heavy perimeter without removing length from the overall shape?

  1. Cutting a horizontal line at 0 degrees
  2. Clipper-over-comb at the nape
  3. Blunt cutting the fringe
  4. Point cutting into the ends Correct answer.

Explanation

Point cutting removes small amounts of weight at the ends while leaving the length of the section intact. Clipper-over-comb and blunt cutting shorten the perimeter, and a horizontal zero-degree line creates a solid edge rather than softening it.

Question 15Hair Care and Haircutting

A client requests a fringe that falls just above the eyebrows. Which guideline should the stylist use to keep the fringe balanced with the rest of the cut?

  1. The crown guideline
  2. The fringe guideline established at the center Correct answer.
  3. The nape guideline
  4. The occipital guideline

Explanation

A fringe is cut from a center guideline so both sides are symmetrical and the length matches across the forehead. Nape and occipital guidelines govern the back of the cut, and the crown guideline is used for layering.

Question 16Hair Care and Haircutting

A stylist is cutting a client's hair with a clipper-over-comb technique at the nape. Which principle keeps the blend even?

  1. Use the clipper without a guard at the skin
  2. Hold the comb at a 45-degree angle and cut against the comb Correct answer.
  3. Cut the hair wet with shears first
  4. Cut only with the comb flat against the scalp

Explanation

Clipper-over-comb blends by holding the comb at a consistent angle and running the clipper along the comb so the cut follows the comb's teeth. A flat comb or no guard removes too much length and creates a hard line.

Question 17Hair Care and Haircutting

Which factor most directly determines how much weight remains at the perimeter of a layered cut?

  1. The color formula used
  2. The elevation angle of the subsection Correct answer.
  3. The type of shampoo used
  4. The drying method

Explanation

Elevation controls how much length is removed from each subsection, so lower angles keep weight at the perimeter while higher angles remove it. Color, shampoo, and drying do not determine the structural weight of the cut.

Question 18Hair Care and Haircutting

A stylist wants to create a square layered shape with a solid perimeter. Which combination is most appropriate?

  1. Vertical sections with 180-degree elevation
  2. Radial sections with 45-degree elevation
  3. Diagonal forward sections with 45-degree elevation
  4. Horizontal sections with 0-degree elevation at the perimeter and 90-degree elevation in the interior Correct answer.

Explanation

A square shape requires a solid perimeter cut at zero elevation, with interior layers cut at 90 degrees to create uniform length within the shape. Vertical or diagonal sections at high elevation would remove the solid edge.

Question 19Hair Care and Haircutting

A client with a prominent jawline wants a cut that softens the face. Which design choice is most appropriate?

  1. A one-length cut pulled straight back
  2. Face-framing layers that begin at the jawline Correct answer.
  3. A blunt chin-length bob with a heavy fringe
  4. A short, tight pixie with no fringe

Explanation

Face-framing layers that start at the jawline direct attention along the face and soften a strong jaw. A heavy blunt bob or a tight pixie exposes the jawline, and a one-length cut pulled back does not frame the face.

Question 20Hair Care and Haircutting

Which statement about cutting curly hair is most accurate?

  1. Curly hair should be cut with a razor for definition
  2. Curly hair should be cut at 180-degree elevation
  3. Curly hair is best cut dry or with minimal tension to respect the curl pattern Correct answer.
  4. Curly hair should always be cut wet to control shrinkage

Explanation

Curly hair shrinks significantly as it dries, so cutting it dry or with minimal tension lets the stylist see the true length and shape. Cutting wet or with a razor can produce an uneven result once the curl springs up.

Question 21Hair Care and Haircutting

A stylist is cutting a graduated bob and notices the sides are shorter than the back. Which correction is most appropriate?

  1. Re-establish the guideline at the back and blend the sides to it Correct answer.
  2. Leave the cut as is and style it
  3. Add more layers to the sides
  4. Re-cut the back to match the shorter sides

Explanation

The guideline governs the shape, so the stylist should re-establish the correct back guideline and blend the shorter sides toward it. Cutting the back to match the error compounds the imbalance, and adding layers does not correct length.

Question 22Hair Care and Haircutting

Which combination of sectioning and elevation would create an A-line bob with length at the front and a shorter back?

  1. Radial sections at 180 degrees
  2. Vertical sections at 90 degrees
  3. Diagonal forward sections with 0-degree elevation at the perimeter Correct answer.
  4. Horizontal sections at 0 degrees throughout

Explanation

An A-line bob uses diagonal forward sections so the front retains length while the back is cut shorter, with zero elevation at the perimeter to keep a solid edge. Horizontal sections at zero degrees produce a level one-length cut, and vertical or radial high-elevation sections create layers.

Question 23Hair Care and Haircutting

A stylist is texturizing a thick, straight bob to reduce bulk while keeping the perimeter solid. Which approach is most appropriate?

  1. Point cut or slide cut in the interior and ends Correct answer.
  2. Cut the perimeter at 45 degrees
  3. Razor the entire perimeter
  4. Use clippers over the comb at the perimeter

Explanation

Interior point cutting and slide cutting remove bulk without changing the solid perimeter line. Razoring the perimeter or cutting at 45 degrees opens the edge, and clipper-over-comb shortens the perimeter.

Question 24Hair Care and Haircutting

Which statement best explains why a stylist should establish a guideline before cutting the rest of the hair?

  1. It speeds up the blow-dry stage
  2. It prevents the need for cross-checking
  3. It removes the need for sectioning
  4. It provides a consistent reference so all subsections match Correct answer.

Explanation

A guideline is the reference length that every subsequent subsection is cut to match, which keeps the shape consistent. It does not replace sectioning or cross-checking, and it is not a drying technique.

Question 25Hair Care and Haircutting

A client with a round face and fine hair wants a short cut with volume on top. Which design choice best meets both goals?

  1. A short graduated cut with height at the crown and tapered sides Correct answer.
  2. A long one-length cut pulled back
  3. A blunt chin-length bob with a center part
  4. A heavy fringe with a blunt perimeter

Explanation

Height at the crown elongates a round face, and tapered sides keep the shape close so fine hair does not look flat. A blunt bob or heavy fringe adds width at the cheeks, and a long one-length cut does not add volume.

Question 26Hair Care and Haircutting

Which haircutting term describes the angle at which the hair is held away from the head before it is cut?

  1. Distribution
  2. Density
  3. Tension
  4. Elevation Correct answer.

Explanation

Elevation, also called projection or lifting, is the angle at which a subsection is held relative to the head form, and it directly controls the amount of layering and weight in the finished shape. Distribution describes where the hair is directed, tension describes the stretch applied, and density describes how much hair is present per square inch.

Question 27Hair Care and Haircutting

A stylist holds a subsection at 90 degrees from the head form and cuts it parallel to the parting. Which shape is being produced?

  1. Increased-length layered form
  2. Uniformly layered form Correct answer.
  3. Solid form
  4. Graduated form

Explanation

Cutting all hair at a consistent 90-degree elevation produces the uniformly layered form, in which length is equalized throughout and weight is distributed evenly. Solid form uses zero elevation, graduated form uses elevation below 90 degrees, and increased-length layering uses elevation above 90 degrees.

Question 28Hair Care and Haircutting

Which guideline is cut at the perimeter of the shape and serves as the length reference for the entire haircut?

  1. Perimeter guideline Correct answer.
  2. Interior guideline
  3. Stationary guideline
  4. Traveling guideline

Explanation

The perimeter guideline sets the outer length of the design and is followed by all subsections that reach that edge. A traveling guideline moves with each subsection, a stationary guideline stays fixed in one place, and an interior guideline is established inside the shape rather than at its outer edge.

Question 29Hair Care and Haircutting

A stylist wants a soft, tapered nape on a short men's cut. Which tool and technique combination is most appropriate?

  1. Shears used with a horizontal parting and zero elevation
  2. Clippers used with a guard and a vertical upward stroke
  3. A razor used against the grain on dry hair
  4. Shears used with a comb as a guide, cutting below the comb teeth Correct answer.

Explanation

Comb-guided shear cutting lets the stylist taper gradually by cutting only the hair that extends beyond the comb, giving controlled length reduction toward the nape. Guards and vertical clipper strokes produce a different, more uniform blend, while razoring dry hair against the grain risks excess removal and irritation.

Question 30Hair Care and Haircutting

When cutting a one-length bob, why does the stylist part the hair into subsections that are no wider than the length of the shears?

  1. To keep the cut line controllable and prevent slipping outside the guideline Correct answer.
  2. To reduce the number of guidelines needed in the nape
  3. To allow the hair to be cut at a higher elevation for movement
  4. To increase the tension on the hair so the line dries shorter

Explanation

Subsections matched to the shear blade allow the stylist to see and control the cut line so each section meets the guideline precisely; wider sections hide hair and invite uneven lines. Tension should stay consistent rather than increased, elevation is determined by the design, and guideline count is a separate decision.

Question 31Hair Care and Haircutting

Which statement accurately describes the effect of cutting hair with a razor rather than shears on the same subsection?

  1. The razor can only be used on wet, fine hair
  2. The razor produces a blunter, heavier perimeter than shears
  3. The razor removes less hair than shears at the same elevation
  4. The razor creates softer, tapered ends that can appear thinner Correct answer.

Explanation

A razor slices hair at an angle, producing tapered ends and a softer edge, which can make the shape appear thinner and more textured. Shears cut straight across and create a blunter line, and razors remove hair readily, so they must be used with control on any hair type.

Question 32Hair Care and Haircutting

A stylist is cutting a graduated shape and wants the line of graduation to sit higher on the head. Which change achieves this?

  1. Shift the distribution to natural fall for all subsections
  2. Reduce tension on the guideline subsection
  3. Cut each subsection at a lower elevation relative to the previous one
  4. Cut each subsection at a higher elevation relative to the previous one Correct answer.

Explanation

In graduation, the elevation of each subsection relative to the one below determines how far the shorter layer sits above the perimeter, so raising elevation moves the graduation line upward. Lowering elevation compresses the graduated band, while distribution and tension affect shape and fit but not the height of the line in this way.

Question 33Hair Care and Haircutting

Which cutting approach best preserves curl pattern when a client with natural coils requests a rounded shape?

  1. Cut the hair with a razor to encourage elongation
  2. Cut the hair wet and comb it straight to check the line
  3. Cut the hair at zero elevation with a blunt perimeter
  4. Cut the hair dry in its natural coil pattern, checking the shape as it springs up Correct answer.

Explanation

Curly and coily hair shrinks substantially when it dries, so cutting it dry in its natural pattern lets the stylist see the true shape and avoid removing too much length. Cutting wet and combing straight misrepresents the finished length, and razoring tends to weaken the coil structure.

Question 34Hair Care and Haircutting

Which term describes the technique of cutting small, shallow V-shaped notches into the ends of a subsection to remove bulk?

  1. Clipper-over-comb
  2. Point cutting Correct answer.
  3. Slicing
  4. Chunking

Explanation

Point cutting uses the tips of the shears to snip into the ends at an angle, softening weight without shortening the overall length much. Slicing and chunking remove larger, more visible sections of hair, and clipper-over-comb is a blending technique used with clippers and a comb.

Question 35Hair Care and Haircutting

A stylist is cutting the sides of a men's cut and wants the hair to lie close to the head while building weight toward the top. Which technique is most suitable?

  1. Cutting the sides with a razor at zero elevation
  2. Cutting the sides at 90 degrees with a horizontal parting
  3. Cutting the sides with a clipper guard at a single length throughout
  4. Cutting the sides with vertical sections and a stationary guideline at the top Correct answer.

Explanation

Vertical sections cut to a stationary guideline near the top of the head allow length to increase upward, keeping the sides close while building weight above. A single guard length produces a uniform wall of hair, and 90-degree horizontal cutting creates even layering rather than closeness at the sides.

Question 36Hair Care and Haircutting

Which factor most directly determines the amount of length removed when a stylist cuts a subsection to a guideline?

  1. The color of the hair
  2. The brand of shears used
  3. The position of the subsection relative to the guideline and the tension applied Correct answer.
  4. The number of subsections in the haircut

Explanation

The distance a subsection must travel to reach the guideline, combined with how much tension is applied, controls how much hair is removed. Hair color, section count, and shear brand do not change the geometric relationship between the hair and the guideline.

Question 37Hair Care and Haircutting

A stylist is creating a long-layered shape and wants the outer layers to fall longer than the inner layers. Which elevation should be used?

  1. Elevation at exactly 90 degrees
  2. Zero elevation
  3. Elevation below 90 degrees
  4. Elevation above 90 degrees Correct answer.

Explanation

Elevation above 90 degrees projects the hair past the head form so outer layers are cut longer than inner ones, producing increased-length layering. Zero elevation creates a solid form, below 90 degrees creates graduation, and exactly 90 degrees creates uniform layering.

Question 38Hair Care and Haircutting

Which practice best protects the integrity of the hair during a precision cut on previously lightened hair?

  1. Cutting with sharp shears and keeping tension moderate and consistent Correct answer.
  2. Using a razor to speed up the cut
  3. Cutting the hair completely dry with dull shears
  4. Applying strong tension to stretch fragile hair straight

Explanation

Lightened hair is more fragile, so sharp shears and moderate, consistent tension minimize stress and produce a clean line. Razors and excessive tension increase breakage risk, and dull shears crush and split the ends rather than cutting them cleanly.

Question 39Hair Care and Haircutting

A client with a long face wants a fringe that visually shortens the face. Which fringe design is most appropriate?

  1. A fringe cut at zero elevation with a razor
  2. A heavy, straight fringe that falls just below the eyebrows Correct answer.
  3. A short, wispy fringe that ends at the hairline
  4. A side-swept fringe that ends at the temple

Explanation

A full, straight fringe that covers the forehead creates a horizontal line that visually shortens a long face. Very short or side-swept fringes leave the forehead exposed and do not create the same shortening effect.

Question 40Hair Care and Haircutting

Which statement best explains why a stylist should check the balance of a finished haircut from multiple angles?

  1. Because hair falls differently when viewed from the front, side, and back, revealing uneven lines Correct answer.
  2. Because shears cut more accurately when viewed from above
  3. Because the client's hair grows faster on one side
  4. Because balance can only be judged on dry hair

Explanation

Hair falls and reflects light differently depending on the viewing angle, so checking the front, sides, and back reveals uneven lines that a single view can hide. Growth rate, shear accuracy, and moisture level do not explain the need for multi-angle checking.

Question 41Hair Coloring and Chemical Texture Services

Which hair color product lightens the natural pigment and deposits new color in a single application?

  1. Semi-permanent color
  2. Temporary color rinse
  3. Demi-permanent color
  4. Permanent color Correct answer.

Explanation

Permanent color uses an alkaline formula with hydrogen peroxide, which lifts the natural melanin and deposits the new pigment simultaneously. Because it opens the cuticle and alters the cortex, the result is lasting and requires a retouch as new growth appears.

Question 42Hair Coloring and Chemical Texture Services

What is the developer strength most commonly used with permanent color for one level of lift?

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

Explanation

Twenty-volume peroxide (6 percent) provides approximately one to two levels of lift and is the standard choice for permanent color placement. Higher volumes increase lift and scalp irritation risk, while 10 volume is generally reserved for deposit-only demi-permanent formulas.

Question 43Hair Coloring and Chemical Texture Services

In the international color level system, what level number represents the darkest black?

  1. Level 10
  2. Level 1 Correct answer.
  3. Level 12
  4. Level 5

Explanation

The level system runs from 1 (black) to 10 (lightest blonde), with some manufacturers extending to 12 for high-lift blondes. Each step represents a visible difference in lightness, so level 1 is the darkest and level 10 the lightest.

Question 44Hair Coloring and Chemical Texture Services

What is the primary function of the activator used in a chemical relaxer service?

  1. Conditioning the hair during processing
  2. Neutralizing the relaxer after processing
  3. Removing mineral buildup before application
  4. Increasing the pH of the relaxer so it can break disulfide bonds Correct answer.

Explanation

The activator raises the pH of the relaxer, usually to around 12 to 13, which allows the product to swell the hair and break disulfide bonds. Without sufficient alkalinity the relaxing action cannot occur.

Question 45Hair Coloring and Chemical Texture Services

Which relaxer type is formulated with guanidine hydroxide and requires mixing two products just before use?

  1. No-lye relaxer Correct answer.
  2. Thioglycolate relaxer
  3. Lithium hydroxide relaxer
  4. Sodium hydroxide relaxer

Explanation

No-lye relaxers combine a calcium hydroxide cream with an activator containing guanidine carbonate, mixed immediately before application. The resulting guanidine hydroxide relaxes the hair with less scalp irritation than sodium hydroxide.

Question 46Hair Coloring and Chemical Texture Services

What does a preliminary strand test primarily determine before a color service?

  1. The exact retail price of the service
  2. Whether the client has had previous chemical services
  3. How the hair will respond to the chosen formula and timing Correct answer.
  4. The client's scalp sensitivity to fragrance

Explanation

A strand test shows how the hair reacts to the formula, processing time, and developer, allowing the stylist to confirm the predicted result before applying product to the whole head. It is the standard safeguard against unexpected color or damage.

Question 47Hair Coloring and Chemical Texture Services

What is the purpose of the patch test before applying a color product?

  1. To predict the final color result
  2. To determine the developer volume needed
  3. To check for an allergic reaction to the product Correct answer.
  4. To measure the porosity of the hair

Explanation

A patch test places a small amount of product on the skin, usually behind the ear or on the inner elbow, to detect an allergic reaction. It is typically performed 24 to 48 hours before the service.

Question 48Hair Coloring and Chemical Texture Services

What is the primary active chemical in an acid permanent wave that breaks disulfide bonds?

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

Explanation

Acid waves use ammonium thioglycolate at a lower pH, around 6.9 to 7.2, to break disulfide bonds while causing less swelling of the hair. The waving lotion is the reducing agent in the process.

Question 49Hair Coloring and Chemical Texture Services

A client with level 4 natural hair wants level 7 blonde. Approximately how many levels of lift are required?

  1. One level
  2. Two levels
  3. Three levels Correct answer.
  4. Five levels

Explanation

Subtracting the natural level (4) from the target level (7) gives three levels of lift. This amount of lift usually calls for a higher-volume developer and careful monitoring to avoid excessive damage.

Question 50Hair Coloring and Chemical Texture Services

What is the underlying pigment exposed when dark brown hair is lightened to the yellow-orange stage?

  1. Red-orange
  2. Red
  3. Yellow-orange Correct answer.
  4. Pale yellow

Explanation

As melanin is lightened, the underlying pigment progresses from red through red-orange, orange, and yellow-orange to pale yellow. The yellow-orange stage corresponds to roughly levels 6 and 7.
