State Board Cosmetology Exam Quiz! MCQ

An antiseptic is applied to tweezed areas during arching to avoid infection. When tweezing, the hair follicles are being pulled out, which can create small openings in the skin. These openings can potentially allow bacteria to enter and cause an infection. By applying an antiseptic, it helps to kill any bacteria present on the skin's surface and reduce the risk of infection.

Oil is suggested for dry cuticles and brittle nails because it helps to moisturize and nourish the cuticles, making them softer and less prone to cracking. Additionally, oil can also help to strengthen and hydrate brittle nails, preventing them from breaking or peeling. Regular use of oil in manicures can improve the overall health and appearance of the nails and cuticles.

Frequent shampooing with highly alkaline shampoo may cause the hair to become dry. This is because alkaline shampoos have a high pH level, which can strip the hair of its natural oils and moisture. This can lead to dryness, brittleness, and frizz. It is important to use a shampoo with a pH level that is closer to the natural pH of the hair, which is slightly acidic, to maintain its health and moisture balance.

To protect a sensitive scalp during a relaxer treatment, it is important to apply a protective base. This is because relaxer treatments involve the use of chemicals that can be harsh on the scalp. Applying a protective base, such as petroleum jelly or a specialized scalp protector, creates a barrier between the scalp and the relaxer, reducing the risk of irritation or burns. This step is crucial in ensuring the safety and comfort of the client during the treatment.

A protective cream is used to create a barrier between the skin and external irritants, such as hair products, that can cause irritation and stains around the hairline. It forms a protective layer on the skin, preventing the products from directly contacting the skin and causing any adverse reactions. This helps to keep the skin healthy and free from any discomfort or discoloration.

Scalp manipulations should not be performed if there are abrasions present. This is because manipulating the scalp in such a condition can cause further irritation, pain, and potential infection. It is important to allow the abrasions to heal before performing any scalp manipulations to ensure the safety and well-being of the individual.

Hair is primarily composed of keratin, a protein that is also found in the outer layer of the skin and nails. Keratin provides strength and structure to the hair shaft, making it resilient and resistant to damage. It is formed by the cells in the hair follicles and is responsible for the texture, strength, and elasticity of the hair. Calcium, cortisone, and magnesium are not primary components of hair.

High elevation in haircutting refers to cutting the hair at a higher angle or lifting it away from the head while cutting. This technique is used to create layers in the hair. By cutting the hair at a higher elevation, the stylist is able to remove more length from the top layers of the hair, resulting in a layered and textured look. This technique is commonly used to add movement, volume, and dimension to the hairstyle.

Before giving a chemical wave, it is important to analyze and shampoo the hair. This is necessary to ensure that the hair is clean and free from any dirt, oils, or product buildup that could interfere with the chemical process. Analyzing the hair helps to determine its condition and any specific needs it may have, such as dryness or damage, which can then be addressed during the shampooing process. By analyzing and shampooing the hair beforehand, the chemical wave can be applied to clean, healthy hair, resulting in better and more consistent results.

A conditioning treatment is the correct answer because it helps to add strength and body to damaged hair. Conditioning treatments are designed to nourish and hydrate the hair, providing it with essential nutrients and moisture. This helps to repair and strengthen the hair, making it less prone to breakage and damage. Additionally, conditioning treatments can also improve the appearance and texture of the hair, making it look healthier and more voluminous. Overall, a conditioning treatment is an effective solution for addressing damage and improving the overall health and appearance of the hair.

During the processing time in chemical waving, the hair has a tendency to expand. This is because the chemical solution used in the waving process breaks down the protein bonds in the hair, allowing it to take on a new shape. As the hair absorbs the solution, it swells and expands, resulting in a larger volume and a different texture.

The correct answer is "where hair porosity is greatest". Hair porosity refers to the hair's ability to absorb and retain moisture and chemicals. When the hair has high porosity, it means that the cuticle layer is more open and allows for faster absorption of chemicals. Therefore, the portion of the hair with the highest porosity will absorb the chemical wave solution faster.

If the cuticle is slightly raised and accepts color products easily, it indicates that the hair is normal. This is because normal hair typically has a cuticle that is slightly raised, allowing it to easily absorb and accept color products.

The correct answer is "bed" because the nail bed is the area underneath the nail plate where the nerves and blood vessels are located. It provides nourishment and support to the nail as it grows. The nail plate is the hard, visible part of the nail, the lunula is the white, crescent-shaped area at the base of the nail, and the cuticle is the layer of skin that protects the nail matrix.

When lightened hair is tinted back to its natural shade, it is necessary to apply a filler. This is because lightening the hair removes its natural pigment, leaving it porous and lacking in color. Applying a filler helps to restore the missing pigment and create a base for the desired natural shade. Without a filler, the tinted color may not adhere properly to the hair, resulting in an uneven or unnatural-looking result.

Coarse and overly curly hair is the most difficult to press because it is thick and has a tight curl pattern. The texture of this hair type makes it resistant to heat and harder to straighten. Additionally, the tight curls can easily revert back to their natural state, making it challenging to maintain a straightened style.

Shears should be used to slither a client's hair. Shears are specifically designed scissors that are used for cutting hair. They have sharp blades that allow for precise and controlled cutting, making them ideal for creating texture and movement in the hair. Slithering is a technique used to remove bulk and add texture to the hair, and shears are the most suitable tool for this technique. Razors, clippers, and thinning shears are not typically used for slithering as they may not provide the desired effect or level of precision.

The peak of a finger wave refers to the highest point or crest of the wave pattern created in the hair. It is the point where the hair is pushed upward and forms a raised ridge. The ridge is created by combing the hair in a specific direction and then using styling techniques to create a wave-like pattern. The ridge is an essential element of a finger wave hairstyle and adds volume and texture to the hair.

Metal implements should be disinfected with a hospital grade solution because it is specifically designed to kill a wide range of bacteria, viruses, and other pathogens that may be present on the surface of the metal implements. This solution is typically more effective than antibacterial soap, which is primarily designed to kill bacteria rather than other types of pathogens. Additionally, hydrogen peroxide may be effective in disinfecting metal implements, but it is not as commonly used or recommended for this purpose. 2% boric acid is not typically used as a disinfectant for metal implements.

Effleurage is a facial massage movement that involves gentle, gliding strokes using the fingertips or palms of the hands. This technique is known for its soothing and relaxing effect on the facial muscles and the overall relaxation of the client. The repetitive and rhythmic nature of effleurage helps to increase blood circulation, reduce tension, and promote a sense of calmness and tranquility.

When a temporary color rinse is applied to normal hair, it coats the cuticle layer. The cuticle layer is the outermost layer of the hair shaft and acts as a protective barrier for the inner layers of the hair. The temporary color rinse forms a thin layer on top of the cuticle, giving the hair a temporary color change without penetrating deeper into the hair shaft. This coating can be easily washed out with shampoo, making it a temporary and non-permanent change to the hair color.

A lightener retouch should first be applied to new growth because this is the area where the hair has grown out and is closest to the scalp. Applying the lightener to the new growth ensures that it will lift and lighten the roots, blending them with the rest of the hair. This helps to maintain a consistent and even color throughout the hair. Applying the lightener to the hair ends or mid-shaft may result in uneven color and potential damage to the already processed hair. The hair follicle is not a suitable area for applying lightener as it is the root of the hair and not visible.

Bones are made of cells, blood, calcium carbonate, and calcium phosphate. The cells in bones help in their growth, repair, and remodeling. Blood vessels supply nutrients and oxygen to the bone cells. Calcium carbonate and calcium phosphate provide strength and rigidity to the bones, making them hard and durable. Therefore, bones are the correct answer.

Disulfide bonds are strong chemical bonds that hold together the protein structure of the hair. Chemical wave solutions, also known as permanent wave solutions, are used to break these bonds and reshape the hair. They contain chemicals like ammonium thioglycolate or ammonium sulfite, which break the disulfide bonds, allowing the hair to be reshaped into curls or waves. Shampooing, winding (hair curling), and neutralizing solutions are not specifically designed to break disulfide bonds, making the chemical wave solution the correct answer.

When removing lightener from hair, it is recommended to rinse with tepid water. Tepid water refers to water that is neither too hot nor too cold, but rather at a moderate temperature. This is because using water that is too hot can cause the hair cuticles to open excessively, leading to damage and dryness. On the other hand, cold water may not effectively remove the lightener. Therefore, rinsing with tepid water provides a balance, allowing for thorough removal of the lightener without causing unnecessary harm to the hair.

Prelightening the hair is usually necessary when using a toner because toners are used to achieve specific hair colors, such as platinum blonde or silver, which require a very light base. Toning is a process that involves depositing color onto pre-lightened hair to neutralize unwanted tones or enhance desired tones. Without prelightening the hair, the toner may not be able to effectively achieve the desired color result.

Onychomycosis is a fungal infection of the nails which can cause discoloration, thickening, and brittleness of the nails. It is a condition that typically requires medical treatment, so a client with onychomycosis should be referred to a physician for proper diagnosis and management. Blue nails can indicate poor circulation or oxygenation, white spots can be a sign of minor trauma or nutrient deficiency, and onychophagy refers to nail biting, which is a habit rather than a medical condition.

Prior to a permanent wave, it is important to drape the client with a towel and plastic cape. This is done to protect the client's clothing from any chemicals or water that may be used during the process. The towel helps to absorb any excess moisture, while the plastic cape acts as a barrier to prevent any liquids from seeping through and staining the clothing. This draping technique ensures that the client remains comfortable and their clothing remains clean and dry throughout the permanent wave procedure.

When the lightener overlaps during a retouch, it means that the product is applied on already lightened or processed hair. This can lead to hair breakage because the overlapping areas receive a higher concentration of chemicals, causing excessive damage to the hair strands. The overlapping of lightener can weaken the hair structure, making it more prone to breakage and damage.

Spirilla is the correct answer because it refers to a coiled, corkscrew-shaped bacteria cell. This type of bacteria is responsible for causing diseases like syphilis and cholera. Bacilli, streptococci, and cocci are not coiled or corkscrew-shaped, so they are not the correct answer.

The texture of hair is determined by its diameter. Hair can be classified as fine, medium, or coarse based on its diameter. Fine hair has a smaller diameter, while coarse hair has a larger diameter. The diameter of the hair shaft affects how the hair feels and behaves, such as its ability to hold styles, its susceptibility to damage, and its overall appearance.

The follicle is the tube-like pocket that contains the hair. It is located within the skin and extends down into the dermis and sometimes even into the subcutaneous tissue. The hair shaft, which is the visible part of the hair, grows from the follicle. The follicle also contains the hair papilla, which is a structure at the base of the hair follicle that supplies nutrients to the growing hair. The arrector pili muscle, on the other hand, is a small muscle attached to the hair follicle that causes the hair to stand up when it contracts.

Sodium hydroxide is a strong base, and when it dissolves in water, it dissociates completely into hydroxide ions (OH-) and sodium ions (Na+). The hydroxide ions are responsible for the basic properties of sodium hydroxide. The pH scale measures the concentration of hydrogen ions (H+) in a solution, and since sodium hydroxide is a base, it has a high concentration of hydroxide ions and a low concentration of hydrogen ions. Therefore, the pH of sodium hydroxide is high, typically ranging from 10.5 to 11.5.

Sterilization is the most effective level of infection control because it completely eliminates or destroys all forms of microorganisms, including bacteria, viruses, and fungi. This process is achieved through various methods such as heat, chemicals, and radiation, ensuring that no infectious agents are left behind. Sanitation and disinfection may reduce the number of microorganisms but may not completely eliminate them. Ventilation helps in reducing the concentration of airborne pathogens but is not sufficient on its own to control infections. Therefore, sterilization is the most effective method for ensuring a completely sterile and safe environment.

Sodium hydroxide is a main ingredient in a chemical hair relaxer because it is a strong alkaline substance that helps break down the protein structure in the hair, allowing it to be reshaped and straightened. It is commonly used in hair relaxers due to its ability to penetrate the hair shaft and alter its texture. Sodium hydroxide is known for its high pH level and can cause damage if not used correctly, so it is important to follow proper safety precautions when using hair relaxers containing this ingredient.

Tint removers are specifically formulated to remove artificial pigment from the hair. This means that they are effective in removing hair dyes or color treatments that have been applied to the hair. Natural pigment refers to the color that is naturally present in the hair and is not targeted by tint removers. Temporary colors are designed to fade over time and can be washed out with regular shampooing, so tint removers are not necessary for their removal. Conditioner build-up refers to a buildup of product residue on the hair and scalp, which can be addressed with clarifying shampoos or regular cleansing routines, rather than tint removers.

Color fillers are specialized preparations that are designed to equalize porosity and deposit a base color in one application. These fillers help to create a uniform and smooth surface, ensuring that the subsequent color application appears even and vibrant. They are commonly used in hair coloring processes to enhance the absorption and longevity of the color.

Tinea capitus is a fungal infection of the scalp that can cause hair loss and inflammation. It is highly contagious and can easily spread to others. Therefore, a cosmetologist would not perform a service on a client with tinea capitus to prevent the infection from spreading to other clients or themselves.

By highlighting the cheekbone, it will appear more prominent and defined. This is because highlighting creates a lighter area on the cheekbone, which attracts light and draws attention to that area. This technique is commonly used in makeup to enhance facial features and create a more sculpted look. Therefore, the correct answer is "emphasized."

A face that is composed of straight lines with a wide forehead and jawline is considered to be square. This is because a square face shape typically has equal width and length, with a strong jawline and a wide forehead. The straight lines in the face structure contribute to the square appearance.

Lightened hair usually requires the shortest processing time in chemical waving because the hair has already been chemically treated to remove its natural pigment. This means that the hair is more porous and can absorb the waving solution more quickly, resulting in faster processing time. Fine, coarse, and resistant hair types may require longer processing times as they are less porous and may need more time for the waving solution to penetrate and create the desired wave pattern.

An emulsion is formed when two or more non-mixable substances are united with the help of a binder or gum-like substance. In an emulsion, one substance is dispersed in the form of small droplets throughout the other substance. The binder or gum-like substance helps to stabilize the emulsion and prevent the separation of the two substances. Emulsions are commonly used in various products such as creams, lotions, and salad dressings.

A conditioner-filler is necessary during a chemical relaxer retouch service because it helps even the porosity of the hair. Porosity refers to the hair's ability to absorb and retain moisture. If the hair has uneven porosity, it may result in an uneven distribution of the relaxer, leading to inconsistent results. The conditioner-filler helps to fill in any gaps or inconsistencies in the hair's porosity, ensuring that the relaxer is applied evenly and consistently throughout the hair shaft. This helps to achieve a more uniform and desired result.

An antiseptic is a chemical compound that is used to slow the growth of bacteria. It is commonly used to disinfect wounds and prevent infection. Antiseptics work by killing or inhibiting the growth of microorganisms on the skin or other surfaces. Unlike antibiotics, which are used to treat infections, antiseptics are primarily used to prevent infections from occurring in the first place. They are commonly found in first aid kits and are an essential component of maintaining hygiene and preventing the spread of bacteria.

Alum powder should be used to stop the bleeding of a minor cut during a manicure. Alum powder has astringent properties, which means it can constrict blood vessels and help stop bleeding. It is commonly used in traditional medicine for its hemostatic (bleeding-stopping) properties.

The mobility of a pin curl is determined by the stem. The stem refers to the central part of the curl, which is responsible for holding the curl in place. The length and flexibility of the stem affect how easily the curl can be moved or adjusted. A longer and more flexible stem allows for greater mobility, while a shorter and less flexible stem restricts movement. Therefore, the stem plays a crucial role in determining the mobility of a pin curl.

Semipermanent hair coloring is designed to last for 4 to 6 shampoos. Unlike permanent hair dyes, which penetrate the hair shaft and last until new hair grows in, semipermanent dyes only coat the outside of the hair and gradually wash out over time. This type of hair coloring is a good option for those who want to experiment with different shades without committing to a long-lasting color change.

The test that determines if a wig is made of human hair or synthetic fiber is the match test. This test involves taking a small strand of hair from the wig and holding it close to a lit match. If the hair melts and smells like burning plastic, it is synthetic. If it burns and smells like burning hair, it is human hair.

Myology is the correct answer because it specifically refers to the study of muscles. Neurology is the study of the nervous system, osteology is the study of bones, and physiology is the study of how living organisms function. Therefore, myology is the most appropriate term to describe the science of muscles.

Keratin is a fibrous protein that forms the base of all horny tissue. Horny tissue includes structures like hair, nails, and the outer layer of the skin. Keratin provides strength, structure, and flexibility to these tissues, allowing them to withstand wear and tear. It also helps protect the skin from injury and provides nourishment to the connective tissue.
