Practicing from Sample Test
Cosmetology Examination #1
To achieve a natural tone, which color additive should you add to a blue base toner when pre lightened hair is pale yellow:
You add red to a blue base toner when pre-lightened hair is pale yellow because red + blue = violet, and violet neutralizes yellow to create a natural, balanced tone without greenish results.
Saturated steam is another method for sterilizing objects with:
Correct: Option d - Moist heat - Saturated steam provides moist heat, which is effective for sterilization by denaturing proteins.
If you have 1 oz Quats solution mix 1 gallon of water, how many percentages of active ingredients should you add?
Correct: Option B - 12.5% is the correct percentage based on standard dilution.
For style set with rollers, the diameter of the roller has the most important effect on:
Correct: Option A - The firmness of the curl
During a shampoo, what should be used when massaging and lathering the client's scalp and hair?
Use the cushions or pads of the fingers when massaging and lathering during shampoo. The pads provide effective pressure to distribute product and increase scalp circulation without scratching or injuring the skin. Fingernails can cause abrasions and discomfort, while palms or thumbs do not provide the same focused action.
Hair that is tapered and thinned well is:
Tapering and thinning remove bulk and weight from the hair shaft, lowering resistance to shape and allowing waves or finger wave patterns to hold more easily. Heavy, blunt hair resists molding because mass pulls styles down, so tapered and thinned hair is generally easier to wave and style.
Covered containers must be used for the storage of:
Covered containers prevent contamination and evaporation, essential for all cosmetics (creams, liquids, lotions) to maintain efficacy and safety. Storing only creams or liquids excludes other forms, while all cosmetics encompasses the broadest category, aligning with hygiene standards in professional settings.
Negative pole in galvanic current produces alkaline reaction and positive pole in galvanic current is best described as:
In galvanic electrotherapy the negative electrode induces an alkaline reaction at the skin surface while the positive electrode produces an acidic reaction. The positive pole acidifies the area and is therefore best described as producing an acidic reaction in contrast to the negative pole's alkaline effect.
When winding the hair in the curling iron close to the scalp, cosmetologist must place a hard rubber comb between the curling iron and the scalp to:
The hard rubber comb acts as a heat barrier so the iron does not contact skin, preventing scalp burns while still allowing close placement and tension. It is not for protecting hair, increasing glide, or preventing hair burning which is controlled by temperature and time.
The immediate effects of massage are first noticed:
Correct: Option C - On the skin.
In blow dry styling, the blower is directed away from the scalp to prevent:
Correct: Option A - Burning scalp
Why should a cosmetologist place the index finger on the glass rake electrode for scalp treatment?
Correct: Option B - Keep low electricity.
Electric clippers should be kept lubricated and sharpened to prevent:
Correct: Option D - The clippers from being rusty
Why is rinsing the hair for at least 3 minutes before applying neutralizer recommended, because it provides:
A thorough rinse for at least three minutes removes residual waving solution and dilutes remaining chemicals, preventing continued reducing action. It also helps reintroduce oxygen and prepares the hair structure so the neutralizer can rebond disulfide links effectively, resulting in a safer, more predictable neutralization and better hair integrity.
When rinsing bleached hair, using cool water will prevent:
Correct: Option D - Brittle
Ultraviolet rays are applied with a lamp at a distance of 30" to 36" from the skin. If the shorter rays are needed, the ultra-violet ray lamp is placed within:
Correct: Option A - 12" from the skin is the correct adjustment for shorter rays.
Split ends are best removed by:
Correct: Option a - Blunt cutting - Blunt cutting trims straight across to remove damaged ends without causing further splitting.
When tinting on extreme resistance hair, you should be first:
Correct: Option B - Soften and slightly bleach the hair
An under development tint in hair coloring on hair prominently grey hair is indicated by:
Correct: Option B - Under development product
An alternation of the properties of a substance without the formation of any new substance is a:
Correct: Option D - Physical change.
Shaping or cutting wet hair is done with a:
A razor is designed to be used on damp or wet hair to reduce friction and prevent tearing. Clippers and trimmers are primarily for dry hair and edging, while shears can cut wet hair but the technique specifically associated with wet shaping in state board style questions is the razor.
Changing the way matter, such as ice cubes melted to water is called physical change, if matter is changed to form new substance such as hydrogen peroxide mix with aniline tint of permanent color is called a:
Correct: Option D - Chemical change.
A small amount of waving lotion will run toward the scalp and the body heat will process the scalp hair quickly. To avoid this problem apply the waving lotion:
Waving lotion that runs toward the scalp can be accelerated by body heat and cause overprocessing or irritation. Applying the lotion a safer distance from the scalp, typically between one half inch and one inch, reduces runoff and direct thermal acceleration at the scalp while still allowing the lotion to act on the hair shaft.
Before applying an aniline derivative hair color, need skin test, or (patch test, allergy test, P.D test) is left undisturbed for a period of:
Correct: Option C - 18 hours – 24 hours is the standard period for a skin test.
If a cold wave lotion accidentally drips on the skin around the face or neck what lotion you can do on skin:
Correct: Option B - Apply neutralizer to the skin.
When shaping the hair style, the cosmetologist must consider the length of hair, texture and:
Correct: Option B - Height of body.
The nail walls are small folds of skin overlapping the sides of the nail:
Correct: Option B - Matrix is the correct term for the area where nail growth occurs.
When picking up articles from the floor, use the muscle of:
Because the thigh muscles do the main lifting work — emphasizing safe body mechanics and protecting the back
The method of cutting the hair straight across while flat of hand against the neck is:
Club cutting also called blunt cutting creates a clean straight line at the ends. It is the classic technique used in nape work with the hand held flat against the neck. Tapering and slithering remove weight by graduating or thinning, and razor cutting leaves softer tapered ends rather than a blunt edge.
To avoid breakage when pressing fine hair, the following is required:
Correct: Option A - Less heat and less pressure
When mix aniline derivative with hydrogen peroxide (H2O2), it cause a chemical reaction called:
Correct: Option A - Oxidation
Nail whiteners are available in the form of:
Traditional nail whitener is a paste applied under the free edge to create an opaque white appearance and stay in place during wear. Liquids and oils lack sufficient hiding power, and loose powder does not adhere without a binder.
Matter is defined as anything that:
Correct: Option c - Occupies spaces - This is the fundamental definition of matter.
When super curly hair has been relaxed and is very fragile, the operator needs to use the following implement for cutting:
Chemically relaxed curly hair can become fragile and prone to breakage. Scissors offer the most controlled, gentle cutting action and allow the stylist to remove damage safely with precise sectioning and point cutting. Clippers or razors can exert more mechanical stress or slicing action that may worsen fragile hair condition.
Applying pressing oil helps the hair to make softer, condition hair, add sheen to pressed hair, help prevent hair breakage and:
Correct: Option D - Help prevent hair from burning or scorching
Your hands need to wash with liquid soap, scrub your hands and lather for at least:
Proper handwashing time is at least 20 seconds to remove dirt, oils, and most transient microorganisms effectively. This is a standard hygiene guideline in both cosmetology and healthcare settings to maintain sanitation. Less time may not adequately break down and rinse away contaminants.
What should the technician do to avoid chemically burning the skin during a permanent wave process?
<div>Explanation:</div><div>During a permanent wave (perm) process, the solution can drip and saturate the cotton band placed around the client’s hairline. If this cotton becomes too wet, it can allow the chemicals to run down onto the skin, causing chemical burns or irritation.</div><div><br></div><div>Therefore, the technician should:</div><div>Remove and replace the saturated cotton band immediately to prevent chemical contact with the skin.</div><div><br></div><div>(Optional additional step): Applying a protective base (barrier cream) around the hairline before starting the process also helps, but the key action during the process to avoid chemical burns is removing the saturated cotton band.</div>
Wavy ridge on a fingernail may be improved by rubbing the nail with:
Buffing with pumice powder gently abrades high spots in the keratin layers to level the plate. Creams and oils only condition and do not remove ridges, and polish remover is a solvent that can dehydrate and worsen surface irregularities.
What would the color result be when you use blue base toner on hair that has been pre-bleached to pal yellow stage:
Correct: Option A - Green cast.
When using scissors to cut hair on comb (over comb), should first cut at:
Correct: Option D - The side of the head
The technique to thin hair with the shear is known as:
Correct: Option D - Slithering
Black hair wants to change to red-brown hair color, but you have only blue base tint in your stock, when you should stop bleaching?
Correct: Option B - Achieves yellow color.
A tint product is applied first on the darkest hair area is:
Correct: Option B - Lighten the hair
For proper hair tapering, the adjacent right next to length of hair strands should not vary more than:
A smooth taper needs small progressive changes. The difference between neighboring lengths should stay within about half an inch to avoid steps or ridges. A quarter inch may be overly strict, while one inch or more creates visible demarcation.
Tweezing, hotwax, cold wax, shaving, chemical depilatories, and thermolysis (electrolysis) are all treatment methods for:
Correct: Option D - Hypertrichosis or hirsuties.
A base cream is applied when giving sodium hydroxide chemical relaxes to:
Correct: Option C - Protect the scalp from the strong chemical.
70% of ethyl alcohol or grain alcohol is equivalent to how much of isopropyl alcohol (rubbing alcohol)?
Correct: Option B - 90%
The carpal bones are classed as:
Carpals are small gliding bones typically categorized as short bones rather than flat or round. Given the choices irregular shape is the best available classification and distinguishes them from flat bones like the scapula.
Before applying a chemical depilatory, it is necessary to give a/an:
Correct: Option c - Skin test - A patch test on the skin checks for allergic reactions or irritation.
Electric vaporizing iron should not be used on pressed hair because they cause the hair to:
Correct: Option a - Revert - The moisture and heat cause pressed hair to revert to its natural curly state.
If using excessive hydrogen peroxide, the hair will become:
Excessive hydrogen peroxide swells and damages the cuticle layer, breaking down the protein structure and increasing porosity. Overuse strips natural oils and structural components, making the hair more porous and fragile. It does not make the hair resistant, nor does it decrease porosity or cause keratinization in this context.
To make sure hair is evenly porous on resistant hair before tinting, you must use the:
When hair is resistant, it means the cuticle layer is very tight, making it difficult for color or tint to penetrate evenly.
Before tinting, you want to even out the porosity so the color absorbs uniformly along the hair shaft.
Why “Cream or oil bleach” is correct:
Cream or oil bleach can be used as a pre-softening or pre-lightening treatment.
It slightly lifts (opens) the cuticle layer without fully bleaching the hair.
This makes the hair more porous and receptive to color, ensuring that tint or dye will take evenly.
The spray machine (otomizer) serves to stimulate nerve endings and:
Correct: Option d - Decrease oil - This helps control oil production on the skin.
How the scissor is properly positioned while the cosmetologist divides subsections the hair in hair cutting?
Correct: Option B - Closing the scissors & facing the cosmetologist.
Converter is mechanical electrical device used to change a direct current (D.C) into an alternating current (A.C) and what device changes an alternating current (A.C) into direct current (D.C).
Correct: Option d - Rectifier - This device converts AC to DC.
Skin condition caused by overactivity and excessive secretion of the sebaceous glands or greasy scales on the skin nose forehead and scalp is often a sign of
Seborrhea results from overactive sebaceous glands leading to excess sebum and greasy scales especially on the scalp nose and forehead. Acne vulgaris and acne simplex are primarily inflammatory and comedonal conditions while acne rosacea is a vascular disorder with flushing and telangiectasia. The hallmark here is oiliness and scaling which defines seborrhea.
When tint on hair with base is green and is previously bleach into pal yellow what color should be added achieves a good result:
Correct: Option D - Red.
Before applying a thioglycolate relaxer product to the hair, should be first:
Correct: Option A - Shampooed
When press the hair, the pressing comb must start:
Correct: Option A - Close to the scalp.
The characteristic of a type of alopecia by the falling out of hair in spots or round patches around the head is called:
Correct: Option D - Alopecia areata.
Vigorously brush the hair before a permanent waving may cause:
Correct: Option B - Irritations scalp
Part of a cell that is vitally important to reproduction is called the:
Correct: Option b - Nucleus - The nucleus contains the genetic material necessary for cell reproduction.
Aniline tint with a pH of 9.5 and pure water with a pH of 7 is considered to be:
Correct: Option b - Acid - Aniline tint at pH 9.5 is slightly alkaline, but the question implies comparison with pure water (pH 7), and the context suggests a misunderstanding; however, based on standard definitions, it's not typically acid.
Hair difficult to bleach up to the yellow must likely contains:
Correct: Option B - Red pigments.
The process whereby the galvanic machine introduces acid pH astringent into the skin is known as:
Correct: Option c - Cataphoresis - This process uses galvanic current to introduce acidic substances.
Secondary lesions are those that develop in the skin during which stage of a disease:
Correct: Option c - Early - Secondary lesions often appear in the early stages as the disease progresses.
If the fastening band is twisted or stitched too tightly on permanent waving curling rods, it may cause:
Correct: Option B - Hair breakage is a common result of tight fastening.
Hair cut short at the nape line這樣的, high at the crown area creates the illusion of:
Correct: Option D - Height
The suction machine usually is used on small sections of the face when treating
Vacuum suction helps mobilize sebum and loosen comedones for extraction and is therefore used on blemished or acne prone skin. It may be irritating for dry or aging skin and is unnecessary on normal skin. Small sectional use helps avoid bruising and over stimulation.
Potential Hydrogen (pH) of the skin and hair range from:
Correct: Option C - 4.5 – 5.5.
When bacteria are in the spore stage, they are:
Correct: Option c - Inactive stage - Spores are a dormant, resistant form where bacteria are inactive.
The earliest sign of developing acne that may lead to inflammatory acne is:
Correct: Option d - Microcomedone - This is the initial clogged pore that can develop into inflammatory acne.
When tapering with the razor, the amount of hair cut in one stroke depends on:
In razor tapering, removal per stroke is controlled by the blade angle relative to the hair shaft. A shallow angle removes little, a steeper angle removes more. Density, razor style, and texture influence technique choice but not the immediate amount removed by a single stroke.
A round thickened patch of epidermis caused by friction is called
A keratoma also called a callus is a localized thickening of the stratum corneum produced by repeated friction or pressure. Chloasma is hyperpigmentation from hormonal influences lentigines are freckles and leucoderma is a loss of pigment. Only keratoma matches a thickened patch from friction.
When applying the cold wave neutralizer, seat the patron in an upright position because:
Correct: Option B - Easier to take care of the dripping.
To avoid overlapping in a “touch up” color the new growth about:
When performing a touch-up, color should be applied starting about 1/16 inch away from the tinted hair to avoid overlapping onto previously colored hair. Overlapping can cause uneven color and damage. Applying too far away would leave a gap, and applying directly on tinted hair causes overprocessing.
Anode forcing alkaline solution through the skin from the negative galvanic for skin:
<p>Why Oil Is Used:</p><p>Oil acts as an insulator and barrier.</p><p>It prevents the alkaline solution (which can be caustic) from directly touching the skin.</p><p>It reduces irritation or chemical burns caused by the galvanic current or the alkaline product.</p><p>It also helps the electrode glide smoothly on the skin’s surface.</p><p>In other words:</p><p>When the anode (positive electrode) pulls the alkaline ions from the negative electrode through the skin, the current can dry or irritate the skin.</p><p>Applying oil before the procedure protects and conditions the skin barrier from that reaction.</p>
For best results when thinning and shaping the neckline, use the:
Detailing at the neckline is most precise with point cutting using the tips of the scissors. This allows controlled removal and soft blending. Clippers can leave hard lines, thinning shears are for interior bulk removal, and full blade scissor cutting lacks edge precision.
Which of the following has acid
Astringents are mildly acidic solutions typically pH 3 to 5 that cause tissue contraction and temporary pore tightening. Cassia oil and lavender are essential oils rather than acids and almond is a food containing fats and proteins. Therefore the item that has an acidic character is an astringent.
When blunt cutting, the hair is held outward by:
Blunt cutting is a one length technique. The comb supports and projects the hair while the shears cut a straight line. Fingers are used for layered or graduated work, clips only section hair, and the scissor blade does not hold the hair.
In cold waving the degree to which the hair will wave or curl depends on one of the following:
Curl size in a permanent wave is determined primarily by the diameter of the rod used. Smaller rods produce tighter curls and larger rods produce looser waves. Product type affects processing strength and time, and density or elasticity affect response, but rod size sets the finished curl size.
Cosmetology textbooks recommend that a steel pusher be used on a moist nail:
Moistening provides lubrication so the metal pusher glides without scratching the nail plate. This has nothing to do with circulation, the nail mantle, or visibility of the lunula.
How many vegetable cells make up a microbe?
In older cosmetology texts microbe refers mainly to bacteria which are single celled organisms. Each microorganism is one cell that reproduces by binary fission, so only one cell makes up a microbe.
When applying a virgin hair with sodium hydroxide chemical relaxer, the cosmetologist should apply:
For virgin sodium hydroxide relaxers apply to the most resistant mid shaft first keeping product off the scalp and porous ends initially. Heat at the scalp speeds processing and ends absorb fastest, so starting about one half inch away prevents over processing and breakage; scalp and ends are addressed last to even out the result.
It is necessary to remove jewelry when using electricity on the client because?
Correct: Option D - Good conductor and can make a shock
A hangnail condition may be corrected by trimming the hangnail and softening the surrounding skin with:
After carefully trimming a hangnail, cuticle oil softens and rehydrates the surrounding skin, reducing splitting and the chance of infection. Naphtha soap is harsh, boric acid is an antiseptic not an emollient, and polish remover dehydrates tissue.
Unwanted hair is removed from large areas by the use of
Soft wax efficiently removes hair over broad regions such as legs arms and back. Tweezing and electric tweezers are slow and suited for small localized areas. Bleaching agents only lighten hair color and do not remove it.
Pathogenic bacteria that require living matter for growth are called
Parasites depend on a living host for nutrients and reproduction which fits pathogenic bacteria that grow only in living tissue. Pimples boils and pus are conditions or byproducts of infection not organisms.
The hair shaping with the surface longer than the sub-surface is the result of:
Correct: Option A - Under cut is the correct technique.
How long does it take to do a P.D test in order to apply artificial eyelashes
A predisposition test for lash adhesive must be performed at least 24 hours before application to detect delayed hypersensitivity reactions. Waiting only minutes is insufficient to reveal a true allergic response.
The permanent wave neutralizer is designed to stop the action of the waving lotion and:
Neutralizer stops the chemical reducing action by re-oxidizing the broken disulfide bonds and reforming them into their new curled shape. It effectively 'rebonds' or 'locks in' the curl pattern established by the waving solution. Relaxing curled hair would undo the wave, and softening or closing the cuticle are secondary outcomes but not the main chemical purpose.
Which one of the following is not a main part of the finger nail?
Correct: Option c - Mantle - The mantle refers to the proximal nail fold, which is skin, not part of the nail itself.
Over processed in permanent waving result in:
Correct: Option B - Frizzy curls
The nail root begins from an actively growing tissue called the:
The matrix is the living tissue that produces the nail plate; its front visible portion appears as the lunula. The eponychium is the proximal fold cuticle area and the hyponychium is under the free edge.
What will happen when the perm rods are placed in a vertical position?
Correct: Option D - Spiral curl
The main ingredient of oil-in-water emulsion is:
Correct: Option C - Water
If while relaxing the hair, your client complains of a stinging sensation in a small area, you should:
Correct: Option D - Spray this area with cool water
When coloring with half lift and half deposit, which volume of Hydrogen peroxide (H2O2) will you use?
Half lift half deposit services use a mid strength developer near the classic twenty volume range that both slightly lifts and deposits. Among the choices provided twenty is not listed and twenty five volume is the closest match; five is too weak for lift, fifteen is mostly deposit, and thirty five is a high lift choice.
When bleach hair, subsection must be used:
When applying bleach, thin and even subsections ensure complete and even saturation of product. A 1/8 inch subsection is recommended to allow the bleach to penetrate uniformly without missing interior sections. Larger subsections may lead to patchy lightening and uneven lift.
The visible portion of the nail, resting upon the nail bed is the:
The nail body also called the nail plate is the visible hard keratin that sits on the nail bed. The free edge extends beyond the fingertip, the lunula is the pale half moon at the base, and the nail root is under the skin within the matrix.
