3.
"Base Color" refers to the predominant tone of color.
Correct Answer
A. True
Explanation
The term "Base Color" refers to the main or dominant tone of color in a given context. It is the primary color that is most noticeable or prominent. Therefore, the statement that "Base Color" refers to the predominant tone of color is true.
4.
The classifications of nonoxidative hair colour are demipermanent and permanent.
Correct Answer
B. False
Explanation
The correct answer is temporary and semipermanent.
5.
Viscosity measures the concentration and strength of hydrogen peroxide.
Correct Answer
B. False
Explanation
VOLUME (vol.) measures the concentration and strength of hydrogen peroxide.
Viscosity refers to the thickness of a liquid that affects how the fluid flows.
6.
Powdered off-the-scalp lighteners contain persulfate salts for quicker and stronger lightening.
Correct Answer
A. True
Explanation
They may dry out more quickly than other types of lighteners, but they do not run or drip. Most powder lighteners expand and spread out as processing continues.
7.
A presoftener acts like a stain to the hair.
Correct Answer
A. True
Explanation
Presoftening raises the cuticle layer of the resistant hair to allow for better penetration of colour. It is applied, processed, and removed. Then, the haircolour is applied.
8.
Hair that looks gun-metal grey is ready to receive colour.
Correct Answer
B. False
Explanation
This hair is extremely porous and fragile. It may be close to its breaking point and should be cut!
9.
The natural colouring pigment found in the cortex layer of the hair is:
Correct Answer
B. Melanin
Explanation
Melanin is the natural coloring pigment found in the cortex layer of the hair. It is responsible for determining the hair's color, ranging from black to brown, red, and blonde. Melanin is produced by specialized cells called melanocytes, which are located in the hair follicles. It is a complex polymer that absorbs and reflects light, giving hair its characteristic color. Melanin also provides protection against harmful UV radiation from the sun.
10.
Hair texture is determined by the diameter of individual hair:
Correct Answer
C. Strands
Explanation
Hair texture refers to the overall look and feel of the hair, and it is determined by the diameter of individual hair strands. The thickness or thinness of the strands directly affects the texture of the hair. Hair with thicker strands tends to have a coarser texture, while hair with thinner strands tends to have a finer texture. Therefore, the correct answer is "strands" because it accurately explains how hair texture is determined.
11.
Fine hair takes colour faster and can look darker because the melanin granules are grouped:
Correct Answer
B. More tightly
Explanation
Fine hair takes color faster and can look darker because the melanin granules are grouped more tightly. When the melanin granules are closely packed together, they can absorb and hold onto more color molecules, resulting in a darker appearance. This is why fine hair can appear to be darker when colored compared to thicker hair types.
12.
The hair with a large diameter that can take longer to process haircolour is:
Correct Answer
C. Coarse-textured hair
Explanation
Coarse-textured hair has a larger diameter compared to fine or medium textured hair. This means that the hair strands are thicker, which can make it more difficult for haircolor to penetrate and process evenly. As a result, it may take longer for the haircolor to fully develop on coarse-textured hair compared to other hair types.
13.
The ability of the hair to absorb liquids is referred to as:
Correct Answer
B. Porosity
Explanation
Porosity refers to the ability of hair to absorb liquids. It is a measure of how easily hair can absorb and retain moisture, oils, and other substances. Hair with high porosity tends to absorb liquids quickly and may become dry or damaged easily, while hair with low porosity has difficulty absorbing liquids and may appear resistant to moisture. Understanding the porosity of hair is important for proper hair care and choosing appropriate products that can effectively moisturize and nourish the hair.
14.
When the cuticle of the hair is lifted and the hair is overly porous and absorbs colour quickly, the hair porosity is defined as:
Correct Answer
A. High
Explanation
When the cuticle of the hair is lifted and the hair is overly porous and absorbs color quickly, it indicates that the hair porosity is high. High porosity means that the hair has gaps and holes in the cuticle, allowing moisture and chemicals to easily enter and exit the hair shaft. This can result in hair that is prone to frizz, tangles easily, and has difficulty retaining moisture.
15.
The melanin that gives black and brown colour to hair is:
Correct Answer
B. Eumelanin
Explanation
Eumelanin is the correct answer because it is the pigment responsible for giving black and brown color to hair. It is produced by specialized cells called melanocytes and its quantity and distribution determine the darkness or lightness of hair color. Eumelanin is also found in the skin and eyes, and variations in its production can result in different hair, skin, and eye colors in individuals.
16.
The system used by colourists to analyze the lightness or darkness of a hair colour is:
Correct Answer
B. The level system
Explanation
The level system is used by colourists to analyze the lightness or darkness of a hair colour. This system categorizes hair colours into different levels, ranging from 1 (darkest black) to 10 (lightest blonde). It provides a standardized way for colourists to communicate and understand the desired shade or tone of hair colour. The level system is widely used in the hairdressing industry to ensure consistent and accurate results when dyeing or lightening hair.
17.
The darkest hair colours in the level system are identified as being a level:
Correct Answer
A. 1
Explanation
The darkest hair color in the level system is identified as being level 1. This is because the level system for hair color ranges from 1 to 10, with 1 being the darkest and 10 being the lightest. Level 1 hair color is typically black or very dark brown, while level 10 is usually a very light blonde or platinum color.
18.
The system used for understanding colour relationships is is the:
Correct Answer
B. Law of colour
Explanation
The correct answer is "law of colour" because the term "law of colour" refers to the principles and theories that govern the relationships between different colors. It is a system or set of rules that helps in understanding how colors interact with each other, how they can be combined or contrasted to create different effects, and how they can be used in various art forms and design applications. The color wheel is a visual representation of the law of color, which organizes colors in a circular format to show their relationships and harmonies. The other options, such as "level system" and "color system," are not specific terms related to understanding color relationships.
19.
Fundamental or pure colours that cannot be achieved from a mixture are:
Correct Answer
C. Primary colours
Explanation
Primary colors are fundamental or pure colors that cannot be achieved from a mixture of other colors. They are considered the building blocks of all other colors. Mixing primary colors together can create a wide range of secondary and tertiary colors, but primary colors themselves cannot be created by mixing other colors. Therefore, primary colors are the correct answer to the question.
20.
The primary colour that brings depth or darkness to any colour is:
Correct Answer
C. Blue
Explanation
Blue is the correct answer because it is a primary color that has the ability to bring depth or darkness to any other color. When blue is added to a color, it creates a darker or more intense shade of that color. This is because blue is a cool color that has a lower intensity compared to warm colors like red or yellow. Adding blue to a color can create shadows, give a sense of depth, or create a darker tone, making it the primary color that brings depth or darkness to any color.
21.
When all three primary colours are present in equal proportions, the resulting colour is:
Correct Answer
B. Black
Explanation
When all three primary colors (red, blue, and yellow) are present in equal proportions, they cancel each other out and create black. This is because each primary color absorbs one of the other primary colors. For example, red absorbs green, blue absorbs orange, and yellow absorbs purple. When all three primary colors are present, they absorb each other, leaving no color to be reflected, resulting in black.
22.
A colour obtained by mixing equal parts of a secondary colour and its neighbouring primary colour on the colour wheel is a:
Correct Answer
C. Tertiary colour
Explanation
When equal parts of a secondary color and its neighboring primary color are mixed, it creates a tertiary color. Tertiary colors are formed by combining a primary color with a secondary color. The primary colors are red, blue, and yellow, while the secondary colors are orange, green, and purple. Mixing equal parts of a secondary color (e.g., orange) and its neighboring primary color (e.g., red or yellow) will result in a tertiary color (e.g., red-orange or yellow-orange). Therefore, the correct answer is tertiary color.
23.
The hue or balance of colour seen in the hair is referred to as:
Correct Answer
D. Tone
Explanation
The hue or balance of color seen in the hair is referred to as "tone." Tone is a term used to describe the warmth or coolness of a color, and in the context of hair, it refers to the overall color that is achieved. It can range from warm tones like red, orange, and gold to cool tones like ash or silver. Tone plays a significant role in determining the overall appearance and character of the hair color.
24.
Tones can be described as:
Correct Answer
A. Neutral
Explanation
Tones can be described as neutral when they do not convey any particular emotion or bias. Neutral tones are often perceived as balanced, calm, and objective. They do not evoke strong feelings or opinions and are commonly used in formal or professional settings where objectivity is valued.
25.
Colours that can look deeper than their actual level are:
Correct Answer
B. Cool tones
Explanation
Cool tones, such as blues and purples, can create an optical illusion that makes them appear deeper than their actual level. This is because cool tones have a receding effect, causing them to appear farther away and creating a sense of depth. On the other hand, warm tones, like reds and oranges, tend to appear more vibrant and closer, while natural and lightest tones do not have the same depth-enhancing effect as cool tones.
26.
Neutral base colours are often used to cover:
Correct Answer
A. Grey hair
Explanation
Neutral base colours are often used to cover grey hair because they help to blend the grey strands with the natural hair color, creating a more cohesive and uniform look. Neutral base colors have equal parts of warm and cool tones, making them suitable for covering grey hair, which can have a mix of both warm and cool undertones. This helps to achieve a natural-looking result and provides good coverage for grey hair.
27.
A colour obtained by mixing equal parts of two primary colours is a:
Correct Answer
D. Secondary colour
Explanation
When two primary colors are mixed in equal parts, the resulting color is called a secondary color. Primary colors are the basic colors that cannot be created by mixing other colors together, while secondary colors are formed by combining two primary colors. Therefore, a color obtained by mixing equal parts of two primary colors is referred to as a secondary color.
28.
Primary and secondary colours that are positioned opposite each other on the colour wheel are:
Correct Answer
A. Complementary colours
Explanation
Complementary colors are positioned opposite each other on the color wheel. When these colors are combined, they create a high contrast and enhance each other's intensity. This creates a visually pleasing effect and is often used in design and art to create balance and harmony. Contrasting colors, on the other hand, may not necessarily be positioned opposite each other on the color wheel and may not create the same harmonious effect when combined. Permanent colors and tertiary colors are not directly related to the concept of colors being positioned opposite each other on the color wheel.
29.
All hair colouring products require a patch test with the exception of:
Correct Answer
B. Temporary colours
Explanation
Temporary colours do not require a patch test because they do not penetrate the hair shaft and only coat the outer layer of the hair. These colours are typically washable and do not contain harsh chemicals that can cause allergic reactions. Patch tests are necessary for semipermanent, permanent, and demipermanent colours as they contain stronger chemicals that can potentially cause skin irritation or allergic reactions.
30.
As part of their composition, all permanent hair colouring products contain both a developer and a(n):
Correct Answer
C. Alkalizing ingredient
Explanation
Permanent hair coloring products contain both a developer and an alkalizing ingredient. The developer helps to activate the color molecules in the hair dye, while the alkalizing ingredient helps to open the hair cuticle and allow the dye to penetrate the hair shaft. This combination of developer and alkalizing ingredient is necessary for the hair dye to effectively color the hair and provide long-lasting results.
31.
Colouring products that have a coating action on the hair and are removed by shampooing are:
Correct Answer
D. Temporary colours
Explanation
Temporary colours are products that have a coating action on the hair and can be easily removed by shampooing. Unlike semipermanent colours, which gradually fade over time, temporary colours provide a temporary change in hair color that can be easily washed out. Ammonia colours and primary colours are not specifically mentioned in the context of the question and do not fit the description of products that are removed by shampooing.
32.
Demipermanent colours are also known as:
Correct Answer
B. No-lift deposit-only colours
Explanation
Demipermanent colours, also known as no-lift deposit-only colours, are a type of hair colouring that do not contain any bleach or ammonia. They are designed to deposit color onto the hair without lightening or lifting the natural hair color. Unlike temporary colours, demipermanent colours last longer and provide more intense color results. They are formulated to add tone and depth to the hair, making them an ideal choice for those who want to enhance their natural hair color without making a drastic change.
33.
The colouring products that are regarded as the best for covering gray hair are:
Correct Answer
D. Permanent haircolouring
Explanation
Permanent haircolouring is considered the best for covering gray hair because it provides long-lasting and full coverage. Unlike demipermanent colours, which gradually fade over time, permanent haircolouring penetrates the hair shaft and permanently changes the hair's natural pigment. This makes it highly effective in covering gray hair and providing a more uniform and consistent color. Liquid haircolouring and protein colours may also provide good coverage, but permanent haircolouring is generally preferred for its longevity and ability to completely cover gray hair.
34.
Dye precursers that combine with hydrogen peroxide to form larger, permanent dye molecules are called:
Correct Answer
A. Aniline derivitives
Explanation
Aniline derivatives are dye precursors that react with hydrogen peroxide to create larger and more stable dye molecules. These derivatives are commonly used in the production of permanent hair dyes, as they provide long-lasting color. The other options, base colors, primary colors, and demipermanent colors, do not specifically refer to dye precursors that react with hydrogen peroxide to form larger dye molecules.
35.
Natural, vegetable and metallic hair colours are also known as:
Correct Answer
C. Gradual colours
Explanation
Natural, vegetable, and metallic hair colours are known as gradual colours because they gradually change the color of the hair over time. These types of hair colours are often used to achieve a more subtle and natural-looking result compared to other types of hair dyes. They typically do not contain harsh chemicals like ammonia and are considered to be a gentler option for coloring hair. The term "gradual" refers to the gradual change in hair color achieved with these types of dyes.
36.
Haircolouring products that change colour gradually by progressive buildup and exposure to air contain:
Correct Answer
B. Metal salts
Explanation
Haircolouring products that change colour gradually by progressive buildup and exposure to air contain metal salts. Metal salts are used in these products to react with the air and gradually change the hair colour over time. The metal salts undergo a chemical reaction with the air, causing the hair colour to darken or change shades. This gradual process allows for a more natural-looking and long-lasting hair colour change.
37.
The most commonly used developer in hair colour is:
Correct Answer
C. Hydrogen peroxide
Explanation
Hydrogen peroxide is the most commonly used developer in hair color. It is a key component in hair color formulations as it helps to activate the color molecules and allows them to penetrate the hair shaft. Hydrogen peroxide also helps to lighten the natural hair color by breaking down the existing pigment. It is a stable and effective developer that provides consistent and reliable results in hair coloring processes.
38.
The standard volume of hydrogen peroxide used to achieve most results with permanent haircolour is:
Correct Answer
B. 20 volume
Explanation
The standard volume of hydrogen peroxide used for achieving most results with permanent hair color is 20 volume. This volume is commonly used as it provides a moderate level of lift and color deposit without causing excessive damage to the hair. Higher volumes like 30 or 40 can be too harsh for some hair types and may result in over-processing or damage. 20 volume is a safer option that still allows for effective color penetration and coverage.
39.
Chemical compounds that lighten hair by dispersing, dissolving and decolourizing the natural pigment are:
Correct Answer
C. Hair lighteners
Explanation
Hair lighteners are chemical compounds that work by dispersing, dissolving, and decolorizing the natural pigment in hair. They are specifically designed to lighten the hair color, either by lifting the existing color or by creating a lighter shade. Hair oxidizers, on the other hand, are substances that help activate the lightening process by breaking down the natural pigment in the hair. Hair decolorizers and hair levels are not accurate terms for substances that lighten hair.
40.
The process where the hair is prelightened and then toned is:
Correct Answer
B. Double-process application
Explanation
The correct answer is double-process application. In this process, the hair is first prelightened to remove its natural color and then toned to achieve the desired shade. This two-step application ensures that the hair is lightened enough to allow the toner to work effectively and create the desired color result. It is commonly used when wanting to achieve dramatic color changes or when going from dark to light shades.
41.
Decolourizing the hair's natural pigment allows the colourist to create the exact degree of:
Correct Answer
D. Contributing pigment
Explanation
Decolorizing the hair's natural pigment removes the existing color, allowing the colorist to add a new color of their choice. This new color is known as the contributing pigment, as it contributes to the final desired shade. By removing the hair's natural pigment, the colorist has more control over the resulting color and can create the exact degree of contribution from the new pigment.
42.
Hair colouring products that are used primarily on prelightened hair to achieve pale and delicate colours are:
Correct Answer
B. Toners
Explanation
Toners are hair colouring products that are used primarily on prelightened hair to achieve pale and delicate colours. Unlike tints, which are used to change the overall hair colour, toners are specifically designed to neutralize unwanted tones or enhance certain shades in prelightened hair. They are typically used after the hair has been bleached or lightened to achieve a desired pale or delicate colour. Rinses, on the other hand, are temporary colouring products that add a subtle tint to the hair, while organic refers to products made from natural ingredients.
43.
During the process of decolourization, natural hair can go through as many as:
Correct Answer
C. 10 stages
Explanation
During the process of decolourization, natural hair can go through as many as 10 stages. This means that the hair can undergo 10 different levels of lightening or bleaching. Each stage represents a different level of color removal, with the hair becoming progressively lighter as more stages are reached. This process is commonly used in hair dyeing or highlighting to achieve a desired lighter shade.
44.
The most critical part of a colour service is the:
Correct Answer
A. Haircolour consultation
Explanation
The haircolour consultation is the most critical part of a colour service because it allows the stylist to understand the client's desired outcome, assess the condition of the hair, and determine the best approach for achieving the desired colour result. During the consultation, the stylist can discuss any previous colour treatments, allergies, or sensitivities the client may have, ensuring that the chosen haircolour is safe and suitable for them. Additionally, the consultation allows the stylist to educate the client about the maintenance and aftercare required for their new haircolour, ensuring long-lasting results and client satisfaction.
45.
Clients with hair in questionable condition who request chemical services should be require to sign a:
Correct Answer
A. Release statement
Explanation
When clients have hair in questionable condition and request chemical services, it is important for them to sign a release statement. This is necessary because the chemical services may further damage their hair or cause adverse reactions. The release statement ensures that the client understands the risks involved and takes responsibility for any potential damage. It protects the salon or stylist from liability and ensures that the client has given informed consent for the requested services.
46.
When applying colour using the bowl-and-brush method, the mixing bowl should be:
Correct Answer
B. Nonmetallic
Explanation
When applying color using the bowl-and-brush method, the mixing bowl should be nonmetallic. This is because metallic bowls can react with the chemicals in the hair color, potentially causing a negative chemical reaction or altering the color result. Nonmetallic bowls, on the other hand, are safe to use as they do not react with the hair color and ensure the desired color outcome.
47.
Before performing a colouring service with an aniline derivative product, the client must have a(n):
Correct Answer
C. Patch test
Explanation
Before performing a colouring service with an aniline derivative product, it is necessary to conduct a patch test. This is because aniline derivatives can cause allergic reactions or sensitivities in some individuals. The patch test involves applying a small amount of the product to a small area of the client's skin, usually behind the ear or on the inner arm, and observing for any adverse reactions such as redness, itching, or swelling. This test helps to ensure the safety and well-being of the client before proceeding with the colouring service.
48.
The U.S. Federal Food, Drug and Cosmetic Act prescribes that a predisposition test be given:
Correct Answer
C. 24 to 48 hours prior to application
Explanation
The U.S. Federal Food, Drug and Cosmetic Act requires that a predisposition test be given 24 to 48 hours prior to application. This time frame allows for enough time to observe any potential adverse reactions or sensitivities to the product before it is applied. Giving the test too close to the application time may not allow enough time for any reactions to manifest, while giving the test too far in advance may not accurately reflect the individual's current sensitivity to the product.
49.
A predisposition test is generally conducted behind the ear or:
Correct Answer
D. Inside the elbow
Explanation
A predisposition test is generally conducted inside the elbow because this area is easily accessible and provides a suitable location for the test. The inside of the elbow has a thin layer of skin, making it easier to prick and collect a blood sample for the test. Additionally, this area is less sensitive compared to other parts of the body, making it more comfortable for the individual undergoing the test. Overall, conducting the test inside the elbow ensures convenience, efficiency, and minimal discomfort for both the tester and the person being tested.
50.
The process that lightens hair and deposits colour in one application is:
Correct Answer
C. Single-process hair colouring
Explanation
Single-process hair coloring refers to a hair coloring technique where both lightening and depositing color are achieved in one application. This process involves using a permanent hair dye that lightens the natural hair color and deposits the desired color at the same time. It is a convenient and time-saving method compared to double-process hair coloring, which requires separate steps for lightening and coloring the hair. Deposit-only color and semi-permanent color do not involve the lightening process, making single-process hair coloring the correct answer.
