Question 1Cosmetology practice (hair, scalp, face and nail services)

Which hair layer is the outermost and protects the inner structures of the hair shaft?

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

Explanation

The cuticle is the tough, overlapping outer layer that shields the cortex and medulla. It controls how chemicals and moisture enter the hair, so its condition governs most service outcomes.

Question 2Cosmetology practice (hair, scalp, face and nail services)

A client's hair is described as having low porosity. What does this mean for chemical services?

  1. The hair has excessive melanin that blocks all chemical absorption
  2. The cuticle is raised, so products absorb quickly and process fast
  3. The hair is missing its cortex and cannot accept color
  4. The cuticle is tightly closed, so products penetrate slowly and may need heat or longer processing Correct answer.

Explanation

Low porosity means the cuticle layers lie tightly together, resisting moisture and chemical entry. A stylist often uses heat, a pre-softening treatment, or extended processing time to get even results.

Question 3Cosmetology practice (hair, scalp, face and nail services)

Which term describes the direction in which hair grows from the scalp, which must be followed to avoid lifting the cuticle?

  1. Hair texture
  2. Hair density
  3. Hair stream Correct answer.
  4. Hair elasticity

Explanation

The hair stream is the natural direction of growth, and shampooing or blow-drying along it keeps the cuticle smooth. Working against the stream roughs the cuticle and creates frizz.

Question 4Cosmetology practice (hair, scalp, face and nail services)

During a scalp massage, which movement should be avoided over the entire scalp?

  1. Fast, heavy friction rubbing across the skin Correct answer.
  2. Slow, circular movements with the fingertips
  3. Light kneading with the pads of the fingers
  4. Gentle upward movements from the hairline

Explanation

Fast friction rubbing can irritate the scalp and tangle hair rather than relax the client. Professional massage uses slow, controlled movements with the finger pads or palms.

Question 5Cosmetology practice (hair, scalp, face and nail services)

Which type of shampoo is formulated to remove product buildup and is generally used only occasionally?

  1. Balancing shampoo
  2. Clarifying shampoo Correct answer.
  3. Medicated shampoo
  4. Moisturizing shampoo

Explanation

Clarifying shampoo uses stronger surfactants to strip residue from styling products and minerals. Because it can be drying, it is used periodically rather than at every wash.

Question 6Cosmetology practice (hair, scalp, face and nail services)

What is the primary purpose of a conditioner applied after shampooing?

  1. To lift the cuticle so color penetrates faster
  2. To smooth the cuticle and restore moisture and manageability Correct answer.
  3. To alter the hair's curl pattern permanently
  4. To remove natural oils from the scalp

Explanation

Conditioners deposit conditioning agents that smooth the cuticle and improve moisture retention and combability. They are not designed to change curl structure or lift the cuticle.

Question 7Cosmetology practice (hair, scalp, face and nail services)

Which draping procedure is correct when giving a basic shampoo and scalp treatment?

  1. Use a shampoo cape over a towel, and place a towel around the neck to protect the client Correct answer.
  2. Use a plastic cape with the collar left open at the front
  3. Drape only a neck strip with no cape
  4. Place the cape directly on the skin with no towel or neck strip

Explanation

A shampoo cape over a towel protects the client's clothing, and the towel at the neck absorbs water and prevents drips. This is the standard sanitary draping for wet services.

Question 8Cosmetology practice (hair, scalp, face and nail services)

A client requests a blunt one-length cut. Which cutting technique produces this result?

  1. Cutting with a razor using a sliding motion
  2. Cutting with deep point-cutting throughout
  3. Cutting with graduated elevation at the crown
  4. Cutting all hair at a single elevation with no over-direction Correct answer.

Explanation

A blunt one-length cut is achieved by cutting the hair at zero elevation to a consistent guide line. Graduation, razoring, and point-cutting all create texture or layered movement instead.

Question 9Cosmetology practice (hair, scalp, face and nail services)

Why does a stylist check the nape and hairline when performing a thermal blow-dry?

  1. These areas hold the least moisture and dry instantly
  2. These areas require the highest heat setting to set the style
  3. These areas contain no hair and need protection only
  4. These areas are more delicate and prone to burns from concentrated heat Correct answer.

Explanation

The nape and hairline have finer hair and thinner skin, so they burn more easily under direct heat. The stylist keeps the dryer moving and tests temperature to prevent injury.

Question 10Cosmetology practice (hair, scalp, face and nail services)

Which tool is best suited for creating a smooth, rounded blow-dry finish on medium-length hair?

  1. A tail comb
  2. A fine-tooth cutting comb
  3. A round thermal brush used with a blow-dryer Correct answer.
  4. A wide-tooth detangling comb

Explanation

A round thermal brush lets the stylist hold tension and roll the hair while directing heat, producing a smooth rounded shape. Combs detangle or section but do not build a bend.

Question 11Cosmetology practice (hair, scalp, face and nail services)

What is the correct first step before applying a chemical relaxer to a client's hair?

  1. Perform a patch and strand test and complete a client consultation Correct answer.
  2. Blow-dry the hair completely straight
  3. Apply conditioner to the entire scalp
  4. Shampoo the hair with a clarifying shampoo

Explanation

A patch test checks for allergic reaction, and a strand test predicts processing time and result. The consultation also identifies prior chemical services and scalp conditions that affect safety.

Question 12Cosmetology practice (hair, scalp, face and nail services)

Which statement about the pH of permanent wave solutions is accurate?

  1. Acid waves swell the cuticle more than alkaline waves
  2. Permanent waves work by removing melanin from the cortex
  3. Alkaline waves swell the cuticle and require a neutralizer to reform bonds Correct answer.
  4. Neutralizers raise the pH to break disulfide bonds

Explanation

Alkaline waving lotion raises pH, swells the cuticle, and breaks disulfide bonds; the neutralizer then lowers pH and rebuilds the bonds in the new shape. Acid waves work at a lower pH with heat.

Question 13Cosmetology practice (hair, scalp, face and nail services)

When mixing permanent hair color, what is the role of the developer?

  1. It adds pigment to the formula
  2. It neutralizes the color after processing
  3. It supplies oxygen to oxidize the dye and lighten melanin Correct answer.
  4. It conditions the hair during processing

Explanation

Developer contains hydrogen peroxide, which oxidizes the dye molecules so they become permanent and lightens natural melanin. Its volume determines the amount of lift.

Question 14Cosmetology practice (hair, scalp, face and nail services)

A client with a warm, golden skin tone asks which hair color family would complement her complexion.

  1. Warm colors such as golden blonde and copper brown Correct answer.
  2. Neutral gray tones only
  3. Green-based fashion shades
  4. Cool colors such as ash blonde and blue-black

Explanation

Warm skin tones harmonize with warm hair colors that share golden, copper, or red undertones. Cool ash or gray shades can make warm complexions look sallow.

Question 15Cosmetology practice (hair, scalp, face and nail services)

How should a stylist determine the base color of a client's natural hair before a color service?

  1. Look only at the ends, which show the true color
  2. Use the color of the eyebrows as the base
  3. Assume the base is level 10 for all clients
  4. Assess the darkest area, usually at the nape or mid-shaft, under proper lighting Correct answer.

Explanation

The natural base level is judged from the darkest, least weathered area, often the nape or mid-shaft, under good light. Ends are usually lighter from sun and prior services and mislead the assessment.

Question 16Cosmetology practice (hair, scalp, face and nail services)

Which product is used to remove artificial color or product buildup from the hair shaft?

  1. Neutral protein filler
  2. Color remover Correct answer.
  3. Styling gel
  4. Developer alone

Explanation

Color remover shrinks or removes artificial dye molecules without lightening natural melanin. It is used when a client wants to correct an unwanted color result.

Question 17Cosmetology practice (hair, scalp, face and nail services)

Which muscle of the face is responsible for closing the eyelid?

  1. Orbicularis oris
  2. Orbicularis oculi Correct answer.
  3. Masseter
  4. Frontalis

Explanation

The orbicularis oculi encircles the eye and closes the eyelid. Knowing facial muscles helps the esthetician apply massage and treatment movements correctly.

Question 18Cosmetology practice (hair, scalp, face and nail services)

What is the purpose of a facial cleansing step at the start of a basic facial?

  1. To exfoliate the stratum corneum deeply
  2. To remove surface oil, dirt, and makeup so treatment products can work Correct answer.
  3. To apply a mask to the skin
  4. To extract comedones from the skin

Explanation

Cleansing removes surface debris and makeup, preparing skin for exfoliation and treatment. Exfoliation, extraction, and masking are separate later steps.

Question 19Cosmetology practice (hair, scalp, face and nail services)

A client has oily skin with visible blackheads. Which step is most appropriate after cleansing and exfoliation?

  1. Using an alcohol-based astringent repeatedly
  2. Softening the skin with warm compresses before gentle extraction Correct answer.
  3. Skipping extraction and applying a rich mask
  4. Applying a heavy occlusive night cream

Explanation

Warm compresses soften sebum and open pores so comedones can be extracted gently. Harsh astringents and heavy creams can worsen oily, congested skin.

Question 20Cosmetology practice (hair, scalp, face and nail services)

Which massage movement is a light, fast, rhythmic tapping used to stimulate the skin?

  1. Effleurage
  2. Tapotement Correct answer.
  3. Vibration
  4. Petrissage

Explanation

Tapotement consists of quick, rhythmic tapping or hacking movements that stimulate circulation. Effleurage is gliding, petrissage is kneading, and vibration is a trembling pressure.

Question 21Cosmetology practice (hair, scalp, face and nail services)

What is the primary function of the lunula on a fingernail?

  1. It is the free edge that protects the fingertip
  2. It is the skin that overlaps the nail plate
  3. It is the visible portion of the nail matrix where new cells are formed Correct answer.
  4. It seals the nail plate to the nail bed

Explanation

The lunula is the whitish half-moon where the matrix is visible, and the matrix produces new nail cells. Damage here can permanently affect nail growth.

Question 22Cosmetology practice (hair, scalp, face and nail services)

Which condition is a bacterial infection of the skin around the nail that requires referral to a physician?

  1. Paronychia Correct answer.
  2. Onychorrhexis
  3. Leukonychia
  4. Onychauxis

Explanation

Paronychia is an infection of the tissue surrounding the nail, often with redness, swelling, and pus. A cosmetologist must not treat it and should refer the client for medical care.

Question 23Cosmetology practice (hair, scalp, face and nail services)

When performing a basic manicure, which step comes immediately before applying polish?

  1. Soaking the hands in warm water for ten minutes
  2. Applying cuticle oil to the entire nail
  3. Cleansing the nail plate to remove oils and debris Correct answer.
  4. Buffing the nail plate with a coarse file

Explanation

The nail plate must be clean and dry so polish adheres and lasts. Oils or moisture left on the plate cause lifting and peeling.

Question 24Cosmetology practice (hair, scalp, face and nail services)

Which safety practice is required when using a nail drill on artificial nails?

  1. Keep the bit moving and avoid prolonged pressure on one spot Correct answer.
  2. Skip eye protection since dust is minimal
  3. Use the highest speed for all nail types
  4. Work only on the free edge at a high angle

Explanation

A moving bit with light pressure prevents heat buildup and nail damage. High speed or prolonged contact can burn the nail bed and injure the client.

Question 25Cosmetology practice (hair, scalp, face and nail services)

Which practice best prevents the spread of infection between clients in a salon?

  1. Disinfecting implements that contact skin or nails after each client Correct answer.
  2. Rinsing implements with water between clients
  3. Storing used implements in a closed drawer without cleaning
  4. Wiping implements with a dry towel

Explanation

Implements that contact skin or nails must be cleaned and then disinfected with an EPA-registered hospital-grade disinfectant after each client. Rinsing or wiping does not kill pathogens.

Question 26Cosmetology practice (hair, scalp, face and nail services)

A client with a round face shape wants a cut that creates the illusion of length. Which styling choice best supports that goal?

  1. Building height at the crown with layered volume Correct answer.
  2. Keeping the perimeter wide and blunt at the jaw
  3. Cutting a heavy fringe straight across the brow
  4. Adding volume at the sides above the ears

Explanation

Height at the crown draws the eye vertically, which visually elongates a round face. Side volume and jaw-level width instead emphasize the horizontal dimension the client wants to reduce.

Question 27Cosmetology practice (hair, scalp, face and nail services)

Which hair texture description refers to the diameter of an individual strand?

  1. Texture Correct answer.
  2. Density
  3. Elasticity
  4. Porosity

Explanation

Texture describes the thickness or diameter of a single strand, classified as fine, medium, or coarse. Density, by contrast, counts how many strands grow per square inch of scalp.

Question 28Cosmetology practice (hair, scalp, face and nail services)

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

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

Explanation

Hair with a raised or damaged cuticle absorbs moisture rapidly, which is the hallmark of high porosity. Such hair also loses moisture quickly and usually needs protein or conditioning treatments.

Question 29Cosmetology practice (hair, scalp, face and nail services)

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

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

Explanation

Surfactants lower surface tension so water can surround and rinse away oily soil. Humectants instead attract and hold moisture, and preservatives protect the product from microbial growth.

Question 30Cosmetology practice (hair, scalp, face and nail services)

During a scalp massage, which movement should be avoided over areas of the head?

  1. Fast friction rubbing that reddens the skin Correct answer.
  2. Slow circular movements with the fingertips
  3. Light tapping with the cushions of the fingers
  4. Gentle kneading of the scalp

Explanation

Fast friction rubbing can irritate or damage the scalp and is not a standard massage movement. Slow circles, kneading, and light tapping are all accepted techniques performed with the finger cushions.

Question 31Cosmetology practice (hair, scalp, face and nail services)

A client arrives with redness, small blisters, and crusting along the hairline. What is the correct stylist response?

  1. Proceed with the service but avoid the affected area
  2. Cover the area with a light foundation and proceed
  3. Apply a medicated shampoo and continue
  4. Refer the client to a physician and do not perform the service Correct answer.

Explanation

Blistering and crusting suggest an infectious or medical scalp condition that is outside the cosmetologist's scope. The service should be declined and the client referred for medical evaluation.

Question 32Cosmetology practice (hair, scalp, face and nail services)

Which term describes the small, cone-shaped area at the base of the hair follicle where cell division occurs?

  1. Hair bulb Correct answer.
  2. Arrector pili
  3. Cuticle
  4. Sebaceous gland

Explanation

The hair bulb is the rounded structure at the base of the follicle that contains the matrix, where new cells form. The arrector pili is the muscle that causes goose bumps, and the sebaceous gland supplies oil.

Question 33Cosmetology practice (hair, scalp, face and nail services)

Which phase of the hair growth cycle is the resting period before a hair is shed?

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

Explanation

Telogen is the resting phase, at the end of which the old hair is shed and a new one begins to form. Anagen is active growth and catagen is the transitional stage.

Question 34Cosmetology practice (hair, scalp, face and nail services)

Which type of hair loss results from a genetic predisposition and typically follows a predictable pattern?

  1. Postpartum hair shedding
  2. Traction alopecia
  3. Alopecia areata
  4. Androgenetic alopecia Correct answer.

Explanation

Androgenetic alopecia is hereditary and follows a recognizable pattern, such as receding temples or thinning at the crown. Alopecia areata is an autoimmune patchy loss, and traction loss comes from tension on the hair.

Question 35Cosmetology practice (hair, scalp, face and nail services)

Which cutting tool should be selected to remove bulk from the interior of a thick, heavy hairstyle?

  1. Tail comb
  2. Thinning shears Correct answer.
  3. Straight razor
  4. Clippers with a guard

Explanation

Thinning shears have one notched blade that cuts only a portion of the hair, reducing bulk without shortening the overall length. A razor creates texture at the ends but is not designed for interior weight removal.

Question 36Cosmetology practice (hair, scalp, face and nail services)

When cutting curly hair dry, why does the stylist account for shrinkage?

  1. The coil pattern makes the hair appear shorter than its true length Correct answer.
  2. Curly hair grows more slowly than straight hair
  3. Curly hair cannot be cut when wet
  4. Dry cutting dulls the shears more quickly

Explanation

Curl pattern pulls the hair into a coil, so the visible length is shorter than the stretched length. Cutting dry lets the stylist see the final shape and avoid removing too much length.

Question 37Cosmetology practice (hair, scalp, face and nail services)

Which styling product provides the strongest hold and is typically applied to dry hair for a finished look?

  1. Hair spray Correct answer.
  2. Leave-in conditioner
  3. Pomade
  4. Setting lotion

Explanation

Hair spray forms a film that holds a finished style and is applied as a final step on dry hair. Setting lotion is applied to wet hair before roller setting, and leave-in conditioner adds moisture rather than strong hold.

Question 38Cosmetology practice (hair, scalp, face and nail services)

Which roller placement creates the most volume at the base of the hair?

  1. On-base Correct answer.
  2. Under-directed
  3. Half-base
  4. Off-base

Explanation

An on-base placement sits the roller directly on its base section, producing maximum lift and volume. Half-base gives moderate volume, and off-base produces the least lift.

Question 39Cosmetology practice (hair, scalp, face and nail services)

Which thermal styling tool uses a heated surface and steam to create curls with a natural finish?

  1. Flat iron
  2. Blow-dryer with a round brush
  3. Steam roller set
  4. Curling iron Correct answer.

Explanation

A curling iron uses a heated barrel to form curls, and steam irons add moisture for a softer set. Flat irons straighten, and a blow-dryer with a round brush smooths rather than forms defined curls.

Question 40Cosmetology practice (hair, scalp, face and nail services)

A client with fine, limp hair wants a style with more body. Which approach is most appropriate?

  1. Use a lightweight volumizing mousse and lift at the scalp Correct answer.
  2. Apply a heavy pomade at the roots before drying
  3. Over-condition with a rich mask before styling
  4. Set the hair in large rollers with heavy setting gel

Explanation

Fine hair is easily weighed down, so lightweight products plus root lift add body without collapse. Heavy products and rich conditioning coat the strand and flatten the style.

Question 41Cosmetology practice (hair, scalp, face and nail services)

Which action is required before a stylist applies a chemical service to a client for the first time?

  1. Perform a predisposition test as required by the product Correct answer.
  2. Shampoo the hair with a clarifying shampoo
  3. Apply a deep-conditioning treatment
  4. Trim the ends to remove split hair

Explanation

A predisposition or patch test checks for allergic reaction before certain chemical services, as directed by the product manufacturer and state rules. Skipping it risks a severe reaction during the service.

Question 42Cosmetology practice (hair, scalp, face and nail services)

Which statement accurately describes the role of a neutralizer in a permanent wave service?

  1. It raises the pH of the hair to make it more alkaline
  2. It rebuilds disulfide bonds into the new curl shape Correct answer.
  3. It swells the cuticle so the wave solution can enter
  4. It removes the curl and returns the hair to its original state

Explanation

The waving solution breaks disulfide bonds, and the neutralizer reforms them in the new shape, locking in the curl. Without proper neutralization the wave would relax and the hair would remain weakened.

Question 43Cosmetology practice (hair, scalp, face and nail services)

A client with a relaxation service has a sodium hydroxide relaxer applied to the scalp. Which precaution protects the client during processing?

  1. Keep the product off the scalp and monitor for burning Correct answer.
  2. Cover the hair with a plastic cap and apply heat
  3. Comb the relaxer through to the ends
  4. Apply the relaxer to the entire head at once

Explanation

Sodium hydroxide is a strong alkaline product that can burn the scalp, so it must be kept off the skin and monitored closely. If the client reports burning, the product must be rinsed immediately.

Question 44Cosmetology practice (hair, scalp, face and nail services)

Which factor determines the amount of lift achieved when mixing permanent color with developer?

  1. The temperature of the room only
  2. The volume of developer used Correct answer.
  3. The color of the client's shirt
  4. The length of the client's hair

Explanation

Developer volume sets the concentration of peroxide, which determines how many levels of lift the color can achieve. The hair's starting level and the chosen formula also influence the final result.

Question 45Cosmetology practice (hair, scalp, face and nail services)

Which technique should be used to retouch a client's regrowth when the previous color was applied six weeks ago?

  1. Apply color only to the new growth at the scalp Correct answer.
  2. Apply color over the entire head from roots to ends
  3. Apply color to the ends first and then the roots
  4. Apply color only to the mid-shaft

Explanation

New growth is the only area that lacks pigment, so retouch color is applied there and processed before being pulled through. Applying to previously colored hair repeatedly causes overprocessing and banding.

Question 46Cosmetology practice (hair, scalp, face and nail services)

A client with dark hair wants to go several levels lighter. Which result is most likely if the hair is lifted too quickly with a high-volume developer?

  1. A permanent straightening effect
  2. A softer, more natural result
  3. Increased shine and elasticity
  4. Brassiness and uneven, porous ends Correct answer.

Explanation

Rapid lifting exposes the underlying warm pigments and can leave the hair uneven and highly porous. Controlled lifting with the correct developer volume produces a more predictable result.

Question 47Cosmetology practice (hair, scalp, face and nail services)

Which step should occur immediately after exfoliation during a basic facial for a client with oily skin?

  1. Apply a heavy night cream
  2. Perform extractions on visible blackheads Correct answer.
  3. Apply a final astringent only
  4. Finish with a massage oil

Explanation

After cleansing and exfoliation, the pores are softened, making extraction of blackheads appropriate when the client's skin tolerates it. Heavy creams and oils are applied later and would interfere with extraction.

Question 48Cosmetology practice (hair, scalp, face and nail services)

Which facial massage movement consists of slow, firm, circular pressure applied with the fingertips?

  1. Vibration
  2. Effleurage
  3. Petrissage Correct answer.
  4. Tapotement

Explanation

Petrissage is a kneading movement using firm, circular pressure that relaxes deeper tissue. Effleurage is a light, gliding stroke, and tapotement is a rapid tapping motion.

Question 49Cosmetology practice (hair, scalp, face and nail services)

Which condition is a contraindication for a facial massage?

  1. Sunburned, inflamed skin Correct answer.
  2. Mature skin with fine lines
  3. Dry skin
  4. Normal combination skin

Explanation

Massaging sunburned or inflamed skin increases irritation and can spread inflammation. Dry, combination, and mature skin are generally appropriate for massage with suitable products.

Question 50Cosmetology practice (hair, scalp, face and nail services)

Which nail shape is recommended for a client who works with her hands and wants to reduce breakage?

  1. Extremely long square tips
  2. Short, rounded oval Correct answer.
  3. Very long stiletto points
  4. Square with sharp corners

Explanation

A short, rounded oval shape distributes stress across the free edge and reduces the chance of snagging or breaking. Long pointed or sharp-cornered shapes catch on objects and break more easily.
