Haircoloring Final Review Questions With Answers

A haircolor brush is used to apply color on the hair when taken from a color bowl. It allows for precise and even application of haircolor, ensuring that the color is distributed evenly throughout the hair. The bristles of the brush help to separate the hair strands and deposit the color evenly, resulting in a professional and seamless haircolor application. Gloves are also necessary to protect the hands from staining and to maintain hygiene during the process. A haircolor hook, on the other hand, is not typically used for applying color but may be used for other purposes such as highlighting or creating texture in the hair.

The cap and hook method involves pulling clean, dry hair through a perforated plastic or latex cap using a crochet hook. This technique is commonly used for highlighting or lowlighting hair, as it allows for precise placement of color. The cap is placed on the head and the hook is used to pull strands of hair through the holes in the cap. This method provides control and accuracy in applying color to specific sections of the hair.

Complementary colors are derived from mixing a primary and secondary color that are situated opposite each other on the color wheel. When these colors are combined, they create a strong contrast and enhance each other's intensity. This concept is commonly used in color therapy, where complementary colors are used to create balance and harmony in the mind and body. Brown color, on the other hand, is not a complementary color but rather a tertiary color created by mixing primary and secondary colors.

Eumelanin is the correct answer because it is a pigment that produces brown to black colors in the hair. Eumelanin is responsible for the dark color of hair, while another pigment called pheomelanin produces red and blonde colors. Atoms and henna are not related to the production of pigments in the hair, so they are not the correct answers.

The applicator bottle is used to hold and apply the color mixture to the hair. It is a container that allows for easy and controlled application of the hair color. The bottle typically has a nozzle or brush attachment that helps to distribute the color evenly onto the hair strands. This allows for precise application and helps to prevent any mess or drips during the coloring process. The applicator bottle is an essential tool for anyone wanting to dye their hair at home or in a salon.

Hair lightener is sometimes referred to as bleach or decolorizer because it is a product used to lighten the color of hair. It works by breaking down the natural pigment in the hair, resulting in a lighter shade. The terms "bleach" or "decolorizer" are often used interchangeably with hair lightener because they describe the process of removing or lightening the color of the hair.

Gloves are used to protect the hair colorist's hands from stains and chemical sensitivity. When applying hair color or working with chemicals, there is a risk of the color or chemicals staining the skin or causing irritation. Gloves act as a barrier between the hands and the color or chemicals, preventing direct contact and reducing the chances of stains or sensitivity. This helps to keep the colorist's hands clean and protected during the hair coloring process.

An allergy is a condition in which the body reacts with hypersensitivity to a substance that is normally harmless. This reaction occurs when the immune system mistakenly identifies the substance as harmful and releases chemicals, such as histamines, to fight against it. This can lead to various symptoms, such as sneezing, itching, rashes, and difficulty breathing. Allergies can be triggered by a wide range of substances, including pollen, dust mites, pet dander, certain foods, and medications. Treatment for allergies often involves avoiding the allergen, taking antihistamines, and in severe cases, receiving allergy shots.

Protective cream is applied along the client's or guest's hairline before hair color application to prevent the color from staining the skin. It acts as a barrier between the hair color and the skin, ensuring that only the hair is colored and the skin remains unaffected. This helps in achieving a clean and professional result, as well as preventing any potential irritation or discomfort to the client.

The term "level" refers to the degree of lightness or darkness of a color. It indicates the intensity or brightness of a color, with lighter colors having a higher level and darker colors having a lower level. The level of a color can be adjusted by adding white or black to it, resulting in lighter or darker shades respectively.

A haircolor hook is a tool that is used to pull hair through a haircolor cap. This tool has a small hook at the end which is inserted into the cap and used to grab sections of hair and pull them through the holes in the cap. It is commonly used in hair coloring processes to achieve highlights or lowlights by selectively coloring certain sections of the hair. Gloves are used to protect the hands while applying haircolor, and a haircolor brush is used to apply the color to the hair.

One of the main and most important skills of a client/guest consultation is listening. This is because effective listening allows the consultant to fully understand the needs, concerns, and preferences of the client/guest. It helps in building rapport, showing empathy, and providing personalized solutions. By actively listening, the consultant can gather important information, ask relevant questions, and ensure that the client/guest feels heard and valued. This skill is crucial in creating a positive and successful consultation experience.

The cuticle is the tough, outer protective covering of the hair. It is responsible for providing strength and protection to the hair shaft. The cuticle consists of overlapping scales that help to prevent damage and breakage. It also helps to retain moisture in the hair, keeping it hydrated and healthy. Overall, the cuticle plays a crucial role in maintaining the integrity and overall health of the hair.

Atoms are the basic building blocks of matter and are made up of protons, neutrons, and electrons. These subatomic particles determine the properties and behavior of atoms. Protons carry a positive charge, neutrons carry no charge, and electrons carry a negative charge. The arrangement and interactions of these particles within an atom determine its chemical and physical properties. Therefore, atoms are the fundamental units that make up all elements and compounds in the universe.

The correct answer is "new growth." In hair coloring, retouch color is applied to the area of the hair strand where new growth occurs. This is the part of the hair that has recently grown out from the scalp and has not yet been colored or treated. Applying retouch color to the new growth helps to cover up any visible roots and maintain a consistent color throughout the hair.

Keratin is the strong, fibrous protein derived from the amino acids that make up the hair. It is responsible for providing strength and structure to the hair. Mascara is a cosmetic product used to enhance the appearance of eyelashes. Anagen refers to the active growth phase of the hair follicle. Therefore, the correct answer is keratin, as it directly relates to the composition of hair.

Temporary hair color coats the hair surface, specifically the cuticle. The cuticle is the outermost layer of the hair shaft, and when temporary hair color is applied, it forms a thin layer over the cuticle, providing a temporary color change. This type of hair color is not permanent and can be easily washed out, making it a popular choice for those who want to experiment with different hair colors without long-term commitment.

Hydrogen peroxide is commonly used as a developer in hair coloring products. It acts as an oxidizing agent, helping to remove the natural color of the hair and allowing the new color to penetrate the hair shaft. By breaking down the natural pigment in the hair, the developer allows the hair dye to bond with the hair fibers, resulting in a permanent color change.

A preliminary strand test involves applying a pre-determined color formula to a small section of hair to preview the end color results. This test helps to determine how the hair will react to the color formula and allows for adjustments to be made if necessary. By conducting a strand test, the hairstylist can ensure that the desired color outcome is achieved and avoid any potential unwanted results.

A line of demarcation refers to a visible mark or border where one color or shade transitions into another. In the context of hair coloring, it specifically refers to a dark band on the hair that occurs when new haircolor overlaps onto previously colored hair. This can happen when the roots of the hair grow out and are not colored, causing a noticeable contrast between the new growth and the previously colored hair. The term "line of demarcation" is commonly used in the beauty industry to describe this distinct line or band.

Before and after every haircoloring service, a client/guest record card is filled out. This card contains important information about the client such as their contact details, previous haircoloring history, allergies, and any specific instructions or preferences. It helps the stylist to keep track of the client's haircoloring journey and ensures that the service is tailored to their needs and preferences. Additionally, the record card can be used for future reference and to maintain a consistent and personalized experience for the client.

The given answer "highlighting" is likely the correct answer because the question mentions a "dimensional haircoloring service" that lightens the hair. Highlighting is a common technique used in hair coloring to add lighter strands or sections to the hair, creating a dimensional and lighter look. The other terms mentioned in the question, such as "line of demarcation" and "applicator bottle," are also commonly associated with highlighting techniques.

Capes are used to cover the client/guest's clothing during hair services in order to protect it from any potential damage. They provide a barrier between the client's clothing and any hair products, dyes, or chemicals that may be used during the service. Capes are typically made of a waterproof or water-resistant material to ensure that any liquids or substances used during the service do not seep through and stain the client's clothing. Additionally, capes also help to keep loose hair and cuttings from getting onto the client's clothing, ensuring a clean and comfortable experience.

The chemical symbol for hydrogen peroxide is H2O2. This is because hydrogen peroxide is composed of two hydrogen atoms and two oxygen atoms, represented by the chemical formula H2O2. This formula indicates that there are two hydrogen atoms and two oxygen atoms present in each molecule of hydrogen peroxide.

Hydrogen peroxide should be stored in a cool, dry dark area to maintain its stability and prevent decomposition. Exposure to light, heat, and moisture can cause the breakdown of hydrogen peroxide, reducing its effectiveness. Storing it in a cool and dry place helps to slow down the chemical reactions that can degrade the compound. Additionally, keeping it in a dark area prevents the degradation caused by exposure to light. This storage method ensures that the hydrogen peroxide remains stable and potent for longer periods.

Pre-softening is the process of placing a product on resistant areas of the hair to initiate the process of opening the cuticle scales. This step prepares the hair for further treatments or processes by making it more receptive to chemical treatments. By pre-softening the hair, the cuticle scales are lifted, allowing for better penetration of the product and ensuring that the desired results are achieved. This helps in achieving a more effective and efficient treatment or styling process.

Neck strips are used to prevent direct contact between the client's/guest's skin and the cape during hair cutting or styling. They are wrapped around the neck, creating a barrier that protects the skin from any potential irritation or discomfort caused by the cape. This helps maintain hygiene and ensures a comfortable experience for the client/guest.

Volume is the correct answer because it refers to the amount of oxygen gas released from hydrogen peroxide. The volume of gas produced is a measure of the quantity of oxygen released during the decomposition reaction of hydrogen peroxide.

Henna is a vegetable dye that is not always encouraged for use in a salon due to interference with other chemicals. This is because henna is a natural dye that can react unpredictably with certain hair lighteners or ammonia-based products commonly used in salons. The interaction between henna and these chemicals can lead to undesirable results, such as uneven color or damage to the hair. Therefore, salon professionals may advise against using henna to ensure the best and safest outcome for the client's hair.

When two primary colors are mixed together, they create a secondary color. Primary colors are the basic colors that cannot be created by mixing other colors, and they are red, blue, and yellow. When any two of these primary colors are mixed, they produce a secondary color. For example, mixing red and blue creates purple, mixing blue and yellow creates green, and mixing red and yellow creates orange. Therefore, the correct answer is secondary.

Porosity refers to the ability of hair to absorb water or liquid within a specific amount of time. It is a measure of how porous or permeable the hair shaft is. Higher porosity hair absorbs water quickly, while lower porosity hair takes longer to absorb moisture. Elasticity refers to the hair's ability to stretch and return to its original length without breaking, while density refers to the number of hair strands on the scalp. Therefore, porosity is the most appropriate term to describe the absorption of water into the hair.

The correct answer is brown color. Brown is a combination of three primary colors - yellow, red, and blue. However, these colors are not mixed in equal proportions. In the case of brown, there are three parts yellow, two parts red, and one part blue. This combination creates a unique color that we perceive as brown.

The correct answer is "anagen." Anagen refers to the growing stage of hair, during which the hair continues to survive and grow. This stage is characterized by the active division of cells in the hair follicle, leading to the production of new hair cells. It is an essential phase in the hair growth cycle and can last for several years, determining the length and thickness of the hair. During anagen, the hair is firmly rooted in the scalp and receives nourishment from the blood vessels, enabling its continuous growth.

A filler is a product that is used to add a missing primary color or equalize the porosity of the cuticle. In hair coloring, fillers are often used to even out the hair color and create a more uniform base before applying the desired color. They can also be used to restore moisture and improve the overall condition of the hair. Fillers help to create a more balanced and consistent result in hair coloring processes.

Color blindness is a condition in which a person is unable to visually differentiate between certain shades of color. This condition affects the perception of colors and can make it difficult for individuals to distinguish between specific hues. In the context of the given options, color blindness is the most relevant term that aligns with the description provided. Preliminary strand testing and hair lightener do not relate to the inability to differentiate colors, making them incorrect options.

When melanin production gradually declines in the cortex layer, it leads to gray hair. Melanin is responsible for giving color to hair, and as its production decreases, the hair loses its pigment and appears gray. This is a natural process that occurs with age, but can also be influenced by factors such as genetics and health conditions.

Viscosity is a property of a fluid that refers to its resistance to flow. It can be thought of as the thickness or heaviness of the liquid. A fluid with high viscosity flows slowly and has a thick consistency, while a fluid with low viscosity flows easily and has a thin consistency. In this context, the correct answer is viscosity because it accurately describes the property being discussed.

Oxidation is a chemical reaction that occurs when oxygen is released from a substance. In this process, a substance loses electrons, resulting in a change in its chemical composition. It often involves the addition of oxygen or the removal of hydrogen from a compound. In the given options, ammonia and viscosity do not involve the release of oxygen, but oxidation does. Therefore, oxidation is the correct answer.

For semi-permanent color application, partings of 1/4 to 1/2 inch are used. This means that when applying the color, the hair is divided into sections that are approximately 1/4 to 1/2 inch wide. This allows for even distribution of the color and ensures that all strands of hair are covered. Using smaller partings may result in a more intense color, while larger partings may lead to uneven color application.

Alkaline products cause the hair to swell.

Fluorescent lighting is an indoor light source that produces cool to drab tones on the skin and hair. This type of lighting is known for its harsh and unflattering effect on colors, making them appear less vibrant and dull. It can affect the perception of haircolor families, as the true shades may not be accurately represented under fluorescent lighting. Additionally, when using haircolor, a filler may be required to counteract the undesirable effects of fluorescent lighting and achieve the desired color result.

Permanent haircolor is the correct answer because it is a hair dye that not only deposits artificial color onto the hair but also lightens the natural haircolor simultaneously. This type of haircolor is designed to provide long-lasting and more dramatic color changes compared to other temporary or semi-permanent options. It typically contains ingredients such as ammonia and hydrogen peroxide that work together to penetrate the hair shaft and alter its natural pigment.

A semi-permanent haircolor is a type of hair dye that does not contain hydrogen peroxide, which is commonly used in oxidative haircolors. Hydrogen peroxide helps to open the hair cuticle and allow the color to penetrate the hair shaft. Since semi-permanent haircolor does not contain hydrogen peroxide, it is considered non-oxidative. This type of haircolor is temporary and gradually fades with each wash, making it a popular choice for those who want to experiment with different colors without committing to a long-lasting change.

White hair occurs when there is a complete lack of pigment in the hair strands. This means that there is no presence of eumelanin (which gives hair its dark color) or pheomelanin (which gives hair its red and yellow tones). As a result, the hair appears colorless or white. This can happen naturally as a person ages and their hair follicles produce less pigment, or it can be caused by certain medical conditions or genetic factors.

Powder lighteners are a type of lightening agent that is used to decolorize the hair. They are considered stronger than other lightening agents and have a faster development time. This means that they are more effective in removing color from the hair and can achieve desired results more quickly. Powder lighteners are commonly used in hair salons and are preferred by professionals for their strength and efficiency.

Corrective color is not an example of dimensional hair coloring because it is a technique used to correct or change the existing hair color. Dimensional hair coloring, on the other hand, involves adding different shades and tones to create depth and dimension in the hair. Highlighting and lowlighting are examples of dimensional hair coloring as they involve adding lighter or darker shades respectively to create contrast and dimension in the hair.

The correct answer is "haircolor families." This suggests that the color hues and intensities on the hair swatches are categorized into different groups based on their similarities. These groups are referred to as haircolor families. This categorization helps in organizing and identifying different shades of hair colors.

A molecule is formed when two or more atoms combine together and maintain their chemical identity. In this process, the atoms share electrons or form chemical bonds, resulting in the formation of a stable structure called a molecule. This allows the atoms to exist as a distinct unit with its own unique properties. Therefore, a molecule is the correct answer as it accurately describes the formation of a stable structure from the combination of atoms.

Pheomelanin is a type of melanin that produces yellow to red pigments in the hair. This pigment is responsible for the lighter hair colors such as blonde, red, and strawberry blonde. Eumelanin, on the other hand, produces brown to black pigments, while mixed melanin is a combination of both eumelanin and pheomelanin. Therefore, pheomelanin is the correct answer as it specifically refers to the pigment that produces yellow to red colors in the hair.
