Hair Care Practice Test

Practice test questions — Hair Care

1. What is the main purpose of a client consultation before a hair service?

   • To sell more products
   • To understand the client's needs, analyze the hair and scalp, and agree on a realistic result ✓
   • To skip the analysis
   • To rush the service

   The main purpose of a client consultation is to communicate with the client to understand what they want, analyze their hair and scalp condition, identify any factors that affect the service (such as previous chemical treatments or contraindications), and agree on a realistic, achievable result. A g…

2. Which four factors are commonly analyzed when assessing a client's hair?

   • Color only
   • Texture, density, porosity, and elasticity ✓
   • Brand, price, length, smell
   • Only the length

   When analyzing hair, cosmetologists commonly assess texture (the diameter of individual strands — fine, medium, coarse), density (how many hairs per area — thin, medium, thick), porosity (the hair's ability to absorb moisture/chemicals), and elasticity (the hair's ability to stretch and return). The…

3. What does hair porosity describe?

   • The hair's color
   • The hair's ability to absorb moisture and chemicals ✓
   • The number of hairs
   • The length of the hair

   Porosity describes the hair's ability to absorb moisture, liquids, and chemicals, which is related to the condition of the cuticle. High-porosity hair (often from damage or chemical processing) has a raised or open cuticle and absorbs quickly but may process unevenly; low-porosity hair has a tight c…

4. What does hair elasticity refer to?

   • How shiny the hair is
   • The hair's ability to stretch and return to its original length without breaking ✓
   • The hair's color depth
   • The scalp's oiliness

   Elasticity refers to the hair's ability to stretch and then return to its original shape without breaking. Hair with good elasticity is healthy and resilient; hair with poor elasticity is weak, may stretch and not recoil, and can break or be damaged during services. Wet hair normally stretches more …

5. Why is the client draped before a service?

   • For decoration
   • To protect the client's skin and clothing and keep them comfortable and clean ✓
   • To make the cape look nice
   • It is not necessary

   Draping protects the client's skin and clothing from water, hair clippings, and chemicals, and keeps them comfortable and dry during the service. The correct drape depends on the service — for example, a different draping setup is used for shampooing, cutting, or chemical services to guard against m…

6. What is the main purpose of shampooing the hair before many services?

   • To color the hair
   • To cleanse the hair and scalp of dirt, oil, and product buildup ✓
   • To cut the hair
   • To permanently straighten it

   The main purpose of shampooing is to cleanse the hair and scalp, removing dirt, excess oil (sebum), perspiration, and product buildup so the hair is clean for the service that follows. A clean scalp and hair allow subsequent services and products to work properly. Shampoo formulas vary (clarifying, …

7. What is the general purpose of a conditioner?

   • To strip the hair
   • To improve the hair's manageability, moisture, and condition, often by smoothing the cuticle ✓
   • To permanently change the color
   • To cut the hair

   Conditioners are used to improve the hair's manageability, add moisture, reduce tangling and static, and improve overall condition, generally by smoothing and helping to close the cuticle and coating or strengthening the hair. Different conditioners serve different needs — for example, instant/surfa…

8. When shampooing, water that is too hot should be avoided primarily because it can:

   • Clean better
   • Be uncomfortable or scald the client and irritate the scalp ✓
   • Improve the haircut
   • Set the style

   Very hot water should be avoided during shampooing because it can be uncomfortable, scald or burn the client's scalp, and cause irritation. Cosmetologists use comfortably warm water and check the temperature, being especially careful around the client's scalp, ears, and neck. Client comfort and safe…

9. In haircutting, what does the term 'elevation' (projection) refer to?

   • The price of the cut
   • The angle at which the hair is held away from the head before cutting ✓
   • The length of the scissors
   • The client's height

   Elevation, also called projection, refers to the angle at which a section of hair is lifted or held away from the head before it is cut. Elevation controls the amount of graduation or layering in a cut: cutting at 0 degrees (no elevation) creates blunt, one-length results, while higher elevations cr…

10. What is a 'guideline' (guide) in haircutting?

    • A safety rule
    • The first section cut that establishes the length, which subsequent sections are matched to ✓
    • A type of comb
    • The client's instructions

    A guideline (or guide) is the section of hair cut first that establishes the length and shape; subsequent sections are combed to and matched against this guide so the cut is even and consistent. Guides can be stationary (all hair brought to one fixed line) or traveling/mobile (the guide moves as you…

11. Cutting hair at 0 degrees of elevation (no lift) typically creates:

    • Heavy layering
    • A blunt, one-length (or solid) shape ✓
    • Maximum graduation
    • Random texture

    Cutting hair at 0 degrees of elevation — keeping the hair down with no lift away from the head — creates a blunt, one-length or solid form, where all the hair falls to a single perimeter line. As elevation increases, the cut develops graduation (stacking) and then layering. The classic blunt bob is …

12. Why should haircutting shears be kept sharp and in good condition?

    • For appearance only
    • Sharp shears cut cleanly and safely; dull shears can damage hair and cause uneven cuts ✓
    • It is not important
    • To cost more

    Sharp, well-maintained shears cut hair cleanly and precisely, which produces better results and is safer and easier to control. Dull or damaged shears can push, fold, or tear the hair, causing split ends, uneven cutting, and extra strain on the cosmetologist's hand. Shears should also be cleaned and…

13. Wet hair being set and dried into a temporary new shape is an example of what kind of change?

    • A permanent chemical change
    • A temporary physical change ✓
    • No change
    • A change to the hair color

    Setting wet hair and drying it into a new shape (for example, with rollers or a blow-dryer and round brush) is a temporary physical change. The hydrogen bonds in the hair are broken by water and reformed in a new position as the hair dries, holding the style until the hair gets wet or absorbs moistu…

14. What is the main safety concern when using hot styling tools like flat irons and curling irons?

    • They use too much electricity
    • They can burn the client's skin/scalp or scorch the hair if used carelessly or at too high a temperature ✓
    • They are too heavy
    • They cannot style hair

    The main safety concern with hot styling tools (flat irons, curling irons, hot rollers) is the risk of burning the client's scalp, ears, neck, or skin, and of scorching or damaging the hair, if the tools are used carelessly or set too hot for the hair type. Cosmetologists protect the client by contr…

15. Why is heat protectant often recommended before thermal styling?

    • To add color
    • To help reduce heat damage to the hair ✓
    • To cut the hair
    • To clean the scalp

    A thermal/heat protectant product is often applied before using hot styling tools to help reduce heat damage to the hair by providing a protective barrier and helping distribute heat more evenly. Repeated high-heat styling without protection can dry out and weaken the hair, leading to breakage and d…

16. Chemical texture services (perms and relaxers) permanently change the hair by:

    • Coating the surface only
    • Breaking and reforming the internal bonds of the hair to a new shape ✓
    • Adding temporary color
    • Cutting the hair

    Chemical texture services such as permanent waves and chemical relaxers create a permanent (chemical) change by breaking the hair's internal disulfide bonds, restructuring the hair, and then reforming those bonds in a new configuration — curl for a perm, or straightened for a relaxer. Because these …

17. Why is a thorough hair and scalp analysis (and often a strand test) essential before a chemical texture service?

    • It is not needed
    • To ensure the hair can safely withstand the service and to predict the result, avoiding damage ✓
    • To choose a cape color
    • To set the price only

    A thorough analysis — and often a preliminary strand test — is essential before a perm or relaxer because these strong chemical services can damage or break hair that is weak, over-porous, previously over-processed, or in poor condition. The analysis checks porosity, elasticity, and condition and id…

18. An open sore, abrasion, or scalp irritation generally means a chemical texture service should be:

    • Done quickly
    • Postponed/not performed, because chemicals can severely irritate or injure broken or inflamed skin ✓
    • Done with extra chemical
    • Done without gloves

    If the client has an open sore, abrasion, or scalp irritation, a chemical texture service should be postponed or not performed, because the strong chemicals can severely irritate, burn, or injure broken or inflamed skin and may indicate the scalp is not in a fit condition. The cosmetologist should r…

19. When performing a chemical service, the cosmetologist should protect themselves by:

    • Skipping gloves
    • Wearing gloves and following the manufacturer's safety directions ✓
    • Working faster
    • Avoiding the consultation

    During chemical services, the cosmetologist should wear appropriate gloves to protect their skin from the chemicals and follow the manufacturer's safety directions, including timing, application method, and ventilation as needed. Many texture and color chemicals can irritate or burn skin with repeat…

20. Why is a patch (predisposition) test recommended before applying certain haircolors?

    • To pick a shade
    • To check whether the client is allergic/sensitive to the product before full application ✓
    • To wash the hair
    • To cut the hair

    A patch (predisposition) test is recommended before applying haircolors that can cause allergic reactions (such as many permanent colors containing certain dyes) to check whether the client is sensitive or allergic to the product. A small amount is applied to the skin (often behind the ear or inner …

21. The level system in haircoloring measures:

    • The price of color
    • The lightness or darkness of a color, from dark to light ✓
    • The brand
    • The scent

    In haircoloring, the level system measures the lightness or darkness of a hair color, typically on a numbered scale from darkest to lightest (for example, low numbers for dark shades up to high numbers for the lightest blondes). Level describes depth only, separate from tone (the warmth or coolness …

22. In haircoloring, 'tone' refers to:

    • How dark the color is
    • The warmth or coolness of a color (such as golden, ashy, red) ✓
    • The price
    • The shine

    Tone refers to the warmth or coolness of a hair color — for example, golden, copper, and red are warm tones, while ash and blue-based shades are cool tones. Tone is distinct from level, which describes lightness or darkness. Both level and tone are needed to describe a color accurately and to formul…

23. Combs and brushes used on clients should be:

    • Used on everyone without cleaning
    • Cleaned and disinfected between clients (or discarded if single-use) ✓
    • Never cleaned
    • Shared between stations only

    Combs and brushes are tools that contact the hair and scalp, so they must be cleaned and disinfected between clients if they are nonporous and reusable, or discarded if they are single-use. Removing hair and debris and then disinfecting prevents the transfer of scalp conditions, infestations, and pa…

24. If a client has a known scalp infection or infestation, the cosmetologist should:

    • Proceed normally
    • Decline the service and refer the client to a physician, and properly handle any tools ✓
    • Use more product
    • Cut the hair shorter

    If a client has a known or suspected scalp infection (such as a fungal infection) or infestation (such as head lice), the cosmetologist should not perform the service and should refer the client to a physician for proper treatment. Performing the service could spread the condition to tools, surfaces…

25. Hair texture (in analysis) refers to:

    • The hair's color
    • The diameter or thickness of individual hair strands (fine, medium, coarse) ✓
    • The number of hairs
    • The hair's length

    In hair analysis, texture refers to the diameter or thickness of the individual hair strands — usually classified as fine, medium, or coarse. Texture affects how the hair responds to services: fine hair may process chemicals faster and hold styles differently than coarse hair. Texture is separate fr…

26. Hair density refers to:

    • Strand thickness
    • The number of individual hairs per square area of scalp (thin, medium, thick) ✓
    • The hair color
    • The porosity

    Density refers to how many individual hairs grow per area of scalp — described as thin/low, medium, or thick/high density. Density is different from texture, which is the diameter of each strand; a person can have fine-textured but dense hair, or coarse but sparse hair. Density influences styling, t…

27. Brushing the hair before a shampoo or chemical service is generally:

    • Required immediately before a chemical service
    • Helpful before shampooing to loosen debris, but the scalp should not be irritated/scratched before a chemical service ✓
    • Never done
    • Only for color

    Brushing before a regular shampoo helps loosen debris and distribute natural oils, but before a chemical service the cosmetologist should avoid vigorous brushing or scratching that could irritate or abrade the scalp, since broken or irritated skin can react badly to chemicals. In general, the scalp …

28. Selecting a shampoo should be based primarily on:

    • The bottle color
    • The client's hair and scalp condition and the service to follow ✓
    • The price only
    • The fragrance only

    Shampoo should be selected based primarily on the client's hair and scalp condition and the service that will follow — for example, a clarifying shampoo to remove buildup, a moisturizing shampoo for dry hair, or a color-safe shampoo for color-treated hair. Matching the shampoo to the hair's needs su…

29. A traveling (mobile) guideline is used mainly to create:

    • A blunt one-length cut
    • Layered or graduated cuts where the guide moves as you work ✓
    • No shape
    • A shorter fringe only

    A traveling (mobile) guideline moves along as the cosmetologist works through the head, with each new section referencing the previously cut hair. This technique is used mainly to create layered or graduated cuts, where length changes gradually. By contrast, a stationary guideline brings all hair to…

30. Sectioning (parting the hair into manageable sections) during a haircut helps to:

    • Waste time
    • Keep the cut controlled, even, and accurate ✓
    • Make the cut uneven
    • Avoid using a guide

    Sectioning — dividing the hair into clean, manageable subsections before and during cutting — helps keep the haircut controlled, even, and accurate. Working section by section ensures no hair is missed, lets the cosmetologist follow the guideline precisely, and produces consistent results. Sloppy or…

31. Backcombing (teasing) is used to:

    • Smooth the hair only
    • Add volume and fullness by pushing shorter hairs toward the scalp ✓
    • Cut the hair
    • Color the hair

    Backcombing, also called teasing, involves combing shorter hairs back toward the scalp to add volume, fullness, and support to a style. It is a temporary, physical styling technique. Done gently and removed carefully afterward, it helps build height and structure in updos and voluminous styles; done…

32. A finishing product like hairspray or pomade is used to:

    • Cleanse the hair
    • Hold or add texture/shine to the finished style ✓
    • Cut the hair
    • Lighten the color

    Finishing products such as hairspray, pomade, wax, or serum are used at the end of styling to hold the finished look in place and/or add texture, definition, separation, or shine. The choice of finishing product depends on the desired effect and the hair type. They are applied after the style is for…

33. The action that breaks the hair's internal bonds in a permanent wave is performed by the:

    • Neutralizer
    • Waving lotion/processing solution ✓
    • Shampoo
    • Conditioner

    In a permanent wave, the waving lotion (processing solution) softens and breaks the hair's internal disulfide bonds so the hair can take the shape of the rod or tool. After processing, a neutralizer is applied to reform (rebond) the bonds in the new curled position and stop the chemical action. Both…

34. The step that reforms the hair's bonds and stops the chemical action after a perm is called:

    • Pre-wrapping
    • Neutralizing (neutralization) ✓
    • Sectioning
    • Draping

    Neutralizing (neutralization) is the step after perm processing that rebonds the hair's disulfide bonds in their new shape and stops the chemical action of the waving lotion. Without proper neutralizing, the hair would not hold the new curl and could be left over-processed and damaged. The neutraliz…

35. Permanent haircolor most often works within which layer of the hair?

    • The cuticle only
    • The cortex (after the cuticle is opened) ✓
    • The medulla only
    • The scalp

    Permanent haircolor works mainly within the cortex of the hair. The product (typically with a developer) raises the cuticle so the color can penetrate into the cortex, where it develops and becomes trapped, producing long-lasting color. This is why permanent color is a chemical change and grows out …

36. If a client shows a positive reaction (redness, itching, swelling) to a patch test, the cosmetologist should:

    • Apply the color anyway
    • Not perform the color service with that product ✓
    • Apply more product
    • Ignore it

    If a patch (predisposition) test produces a positive reaction — such as redness, itching, burning, or swelling at the test site — the cosmetologist must not perform the haircolor service with that product, because the client is showing a sensitivity or allergy that could cause a serious reaction if …

37. Clippers and clipper blades that contact the skin should be:

    • Never cleaned
    • Cleaned and disinfected between clients per manufacturer directions ✓
    • Oiled only, never disinfected
    • Shared without cleaning

    Clippers and their blades contact the hair and skin, so they must be cleaned and disinfected between clients according to the manufacturer's directions (which may include removing hair, using a blade cleaner/disinfectant spray, and oiling). Proper maintenance prevents the transfer of pathogens and k…

38. Good posture and ergonomics for the cosmetologist help to:

    • Style hair faster only
    • Prevent strain and long-term injury to the body during repetitive work ✓
    • Impress clients
    • Replace tool maintenance

    Maintaining good posture and ergonomics — such as keeping the back straight, positioning the client at a good height, not over-reaching, and holding tools properly — helps prevent muscle strain, fatigue, and long-term repetitive-stress injuries that are common in a physically demanding, repetitive p…

39. Documenting a client's service history (such as previous chemical treatments) is useful because:

    • It wastes time
    • Prior treatments affect how the hair will respond to new services and helps avoid damage ✓
    • It is only for billing
    • It has no effect on services

    Documenting a client's service history — especially previous chemical treatments like color, perms, relaxers, or keratin services — is useful because prior chemical work significantly affects how the hair will respond to a new service and the risk of damage (for example, layering incompatible chemic…

40. Scalp massage during shampooing primarily helps to:

    • Cut the hair
    • Cleanse and stimulate the scalp and relax the client ✓
    • Color the hair
    • Straighten the hair

    A gentle scalp massage during shampooing helps to cleanse the scalp thoroughly, stimulate circulation, and relax the client, contributing to a pleasant service experience. It should be done with the pads of the fingers (not nails) to avoid scratching or irritating the scalp — important because an ir…

41. Cross-checking a haircut means:

    • Charging twice
    • Checking the cut by parting and combing the hair in the opposite direction to verify evenness ✓
    • Cutting twice as fast
    • Skipping sections

    Cross-checking means re-checking a completed haircut by parting and combing the hair in the opposite direction from how it was cut (for example, checking horizontal sections vertically) to verify that the lengths are even and the shape is balanced. It catches any unevenness that might be missed when…

42. Wrapping or roller placement to create a style sets the hair through:

    • A permanent chemical change
    • Temporary physical reshaping using moisture and drying ✓
    • Cutting
    • Coloring

    Using rollers, pin curls, or wrapping to set a style reshapes the hair through a temporary physical change: water breaks the hydrogen bonds, the hair is molded into the new shape, and drying re-sets those bonds in the new position so the style holds until moisture is reintroduced. No permanent chemi…

43. Compared with a perm, a chemical relaxer is used to:

    • Add curl
    • Reduce or remove curl, straightening the hair ✓
    • Color the hair
    • Cut the hair

    A chemical relaxer is used to reduce or remove natural curl, straightening the hair, whereas a permanent wave is used to add curl or wave. Both are chemical texture services that permanently restructure the hair by breaking and reforming its internal bonds, and both demand careful analysis, scalp pr…

44. Developer (for example, hydrogen peroxide) is used in permanent color mainly to:

    • Cleanse the hair
    • Help develop the color and, depending on strength, lift natural pigment ✓
    • Cut the hair
    • Cool the scalp

    Developer, commonly hydrogen peroxide at various strengths (volumes), is mixed with permanent haircolor to activate and develop the color and, depending on its strength, to lift (lighten) the hair's natural pigment so the new color can deposit. Higher-volume developers lift more. Developer must be u…

45. Before reusing a nonporous styling tool that touched a client's skin, the cosmetologist must:

    • Just wipe it on a towel
    • Clean and disinfect it ✓
    • Only rinse it
    • Do nothing

    Any nonporous styling tool that contacts a client's skin or hair (combs, sectioning clips, metal-handled brushes, etc.) must be cleaned and then disinfected before it is used on another client. A quick wipe or rinse is not sufficient to kill pathogens. This applies the salon's core clean-then-disinf…

46. A realistic consultation outcome means the cosmetologist should:

    • Promise any result the client wants
    • Be honest about what is achievable given the hair's condition and history ✓
    • Avoid discussing limits
    • Always refuse service

    Part of a good consultation is being honest with the client about what is realistically achievable given their hair's current condition, length, texture, and chemical history — for example, explaining that a dramatic lightening may require multiple sessions or could risk damage on compromised hair. …

47. Allowing freshly thermally styled hair to cool before brushing out generally helps the style to:

    • Fall flat immediately
    • Set and hold better ✓
    • Change color
    • Become damaged

    Allowing hair that has been curled or shaped with thermal tools to cool before brushing or finishing generally helps the style set and hold better, because the hair's bonds re-form as it cools in the new shape. Brushing out curls while they are still hot can relax them prematurely. This is a practic…

48. Following the manufacturer's processing time during a chemical service is important because:

    • It is optional
    • Over- or under-processing can damage hair or give poor results ✓
    • Time does not matter
    • Longer is always better

    Following the manufacturer's specified processing time during a chemical service (perm, relaxer, or color) is important because leaving the product on too long (over-processing) can severely damage or break the hair, while removing it too soon (under-processing) gives weak or incomplete results. Tim…

49. The pull/stretch test on wet hair is used mainly to assess:

    • Color
    • Elasticity ✓
    • Density
    • Price

    Gently stretching a wet strand to see how far it extends and whether it returns is a way to assess elasticity. Healthy hair with good elasticity stretches and recoils; weak hair may stretch and break or fail to return, signaling damage. Because chemical services stress the hair, poor elasticity is a…

50. Listening carefully and confirming what the client wants before starting helps to:

    • Waste time
    • Avoid miscommunication and dissatisfaction with the result ✓
    • Skip the analysis
    • Raise the price

    Actively listening to the client and confirming the desired result (sometimes using photos or visual references) before starting helps avoid miscommunication that can lead to a result the client did not want. Combined with the hair analysis, this ensures the agreed plan is both what the client wants…

51. A clarifying shampoo is used mainly to:

    • Add heavy moisture
    • Remove product buildup and residue ✓
    • Color the hair
    • Cut the hair

    A clarifying shampoo is formulated to deep-cleanse and remove product buildup, residue, and mineral deposits from the hair. It is useful before certain chemical services or when buildup is weighing the hair down, but it can be drying if overused. Other shampoos (moisturizing, color-safe, etc.) serve…

52. Why use the pads of the fingers rather than the fingernails during shampooing and scalp massage?

    • It looks better
    • To avoid scratching or injuring the scalp ✓
    • Nails clean better
    • It is faster

    Cosmetologists use the pads (cushioned tips) of the fingers, not the fingernails, during shampooing and scalp massage to avoid scratching, abrading, or injuring the scalp. A scratched or broken scalp is uncomfortable and can be a problem before chemical services, where broken skin reacts badly to ch…

53. Holding consistent tension on a subsection while cutting helps to:

    • Create random results
    • Produce an even, accurate line ✓
    • Damage the hair
    • Avoid using a guide

    Maintaining consistent, even tension on each subsection of hair while cutting helps produce an even, accurate cutting line. Uneven tension — pulling some hairs tighter than others — causes an uneven result once the hair is released and falls into place. Tension should also be appropriate (not so tig…

54. Point cutting (cutting into the ends at an angle) is generally used to:

    • Create a blunt line
    • Soften ends and remove weight, adding texture ✓
    • Color the hair
    • Set a perm

    Point cutting — cutting into the ends of the hair at an angle with the tips of the shears — is a texturizing technique used to soften a blunt line, remove weight, and add movement and texture to the ends. It contrasts with a straight, blunt cut that creates a solid line. Texturizing techniques like …

55. Diffusing while blow-drying curly hair is used to:

    • Straighten it completely
    • Dry the hair while preserving and enhancing its natural curl ✓
    • Cut the hair
    • Bleach the hair

    A diffuser attachment on a blow-dryer spreads the airflow over a wider area and reduces direct force, which helps dry curly or wavy hair while preserving and enhancing its natural curl pattern and reducing frizz. Blasting curly hair with concentrated high airflow tends to disrupt the curl and create…

56. Which is a temporary, not permanent, way to change hair color for a single styling session or short term?

    • Permanent color with developer
    • A temporary rinse or color that mostly coats the surface and washes out ✓
    • A chemical relaxer
    • A permanent wave

    A temporary color (such as a temporary rinse, spray, or some wash-out products) changes the hair color by mostly coating the surface/cuticle and washing out after one or a few shampoos, making it a temporary change. Permanent color penetrates the cortex and lasts until it grows out. (Relaxers and pe…

57. Why should incompatible chemical services not be layered carelessly (for example, certain treatments over others)?

    • It saves product
    • Combining incompatible chemical processes can cause severe damage or breakage ✓
    • It improves shine
    • It has no effect

    Layering incompatible chemical services — for example, applying certain strong chemicals over hair already treated with another incompatible process — can cause severe damage, breakage, or unpredictable reactions, because the hair's bonds and condition may not tolerate the combination. This is why k…

58. Performing a strand test during a chemical service allows the cosmetologist to:

    • Skip processing
    • Monitor how the hair is processing and judge when it is done ✓
    • Avoid neutralizing
    • Color the hair

    Taking periodic strand tests during a chemical service (gently checking a test strand) lets the cosmetologist monitor how the hair is processing — for example, checking curl formation during a perm or color development — and judge when the desired result is reached so the product can be rinsed/neutr…

59. Demi- and semi-permanent colors generally differ from permanent color in that they:

    • Last longer than permanent
    • Are less permanent and fade gradually, with little or no lift of natural pigment ✓
    • Cut the hair
    • Cannot add tone

    Demi-permanent and semi-permanent colors are generally less long-lasting than permanent color: they deposit color and fade gradually over a number of shampoos, and they typically do little or no lifting (lightening) of the natural pigment, since they use little or no developer (or a low-strength one…

60. Why should color or lightener be applied carefully and not left to process beyond directions?

    • Color never damages hair
    • Over-processing, especially with lighteners, can seriously damage or break the hair ✓
    • It saves money
    • Longer always looks better

    Color, and especially lightener (bleach), must be applied carefully and processed only for the time the manufacturer and strand testing indicate, because over-processing — particularly with strong lighteners — can seriously dry out, weaken, and break the hair. Lightening is one of the more damaging …

61. A neck strip or towel used under the cape during a service helps to:

    • Color the hair
    • Prevent the cape from touching the client's skin directly and support sanitation/comfort ✓
    • Cut the hair
    • Replace disinfection

    Placing a clean neck strip or towel between the cape and the client's neck prevents the cape from touching the client's skin directly, which supports sanitation (the cape is not contacting bare skin of multiple clients) and adds comfort. Capes and linens should be clean for each client. This is part…

62. Why check the scalp (not just the hair) during analysis?

    • Scalp condition does not matter
    • To detect any disorders, irritation, or contraindications before performing a service ✓
