The correct answer is "sterilization, disinfection, sanitation." This order is based on the level of effectiveness in eliminating or reducing the presence of microorganisms. Sterilization is the highest level, as it completely eliminates all forms of microbial life. Disinfection is the next level, which kills or inactivates most pathogenic microorganisms, but may not eliminate all types. Sanitation is the lowest level, which reduces the number of microorganisms to a safe level but does not necessarily eliminate all of them.

Epilation is the removal of hair from the root, which includes methods like tweezing, waxing, and sugaring. These techniques remove hair from beneath the skin's surface, ensuring a longer-lasting result compared to depilation, which only removes hair from the surface. Photo-epilation, on the other hand, uses intense pulsed light (IPL) to target and destroy hair follicles, while electrolysis involves the use of an electric current to permanently remove hair. Therefore, tweezing falls under the category of epilation as it removes hair from the root.

The correct answer is 8.2-9.6. This pH range is the most common for an ammonium thioglycolate perm because it provides the optimal conditions for the chemical reaction to occur. Ammonium thioglycolate is a reducing agent that breaks the disulfide bonds in the hair, allowing it to be reshaped. This reaction is most effective in a slightly alkaline environment, which is why the pH range of 8.2-9.6 is recommended. A pH below or above this range may result in an incomplete or uneven perm.

The term "spiral" is the correct answer because it refers to the technique of rolling the hair from the scalp to the ends in a spiral shape. This technique creates tight, bouncy curls that are uniform in size and shape. The other options, croquignole, piggyback, and tiered, do not accurately describe the rolling technique used for creating spiral curls.

To achieve a more natural look when cutting a wig, it is recommended to taper the ends. Tapering the ends involves gradually reducing the length of the hair towards the ends, creating a softer and more blended effect. This technique helps to avoid a blunt and unnatural appearance, allowing the wig to mimic the look of real hair.

The approximate pH of most alkaline permanent wave solutions is between 8.2 and 9.6. This pH range is necessary for the chemical process of permanent waving to occur effectively. Alkaline solutions help to break down the disulfide bonds in the hair, allowing it to be reshaped into a new curl pattern. The pH range mentioned ensures that the solution is strong enough to break the bonds but not too strong to cause excessive damage to the hair.

A cap wig is usually hand-knotted or hand-tied and has a mesh-like base to which the hair is attached. This type of wig provides a comfortable and secure fit as the cap molds to the shape of the wearer's head. The mesh base allows for breathability and a natural appearance as it mimics the scalp. Cap wigs are popular for their versatility and ability to be styled in various ways.

During the processing stage of the permanent wave or chemical relaxer process, reduction occurs. This is the stage where the chemical product is applied to the hair, and it works to break down the disulfide bonds in the hair shaft. This allows the hair to be reshaped or relaxed, depending on the desired outcome. The reduction process alters the structure of the hair, making it more malleable and able to hold the desired shape or texture.

A healthy nail cuticle will typically be loose and pliable because the cuticle is the layer of skin that protects the nail matrix and the nail bed from infection. If the cuticle is loose, it means that it is not tightly adhered to the nail plate, allowing it to move and flex along with the nail. This flexibility is important for the overall health of the nail as it allows for proper growth and prevents the cuticle from tearing or becoming damaged. Additionally, a pliable cuticle indicates that it is well-hydrated and moisturized, which is essential for maintaining healthy nails.

Both metallic salts/dyes and henna can leave the hair unfit for additional chemical services. Metallic salts/dyes can react with other chemicals, causing unwanted color changes or damage to the hair. Henna is a natural plant-based dye that can also interfere with the results of chemical services. Therefore, both A (metallic salts/dyes) and B (henna) can leave the hair unfit for additional chemical services.

Disulfide bonds are broken and then reformed in the processing action of both permanent waving and chemical relaxer services. Disulfide bonds are strong chemical bonds that hold together the protein structure of the hair. In permanent waving, these bonds are broken using a reducing agent, allowing the hair to be reshaped into a new curl pattern. In chemical relaxer services, the disulfide bonds are broken using a relaxing agent, allowing the hair to be straightened. After the desired shape is achieved, the disulfide bonds are reformed using an oxidizing agent, locking in the new shape.

A capless wig is a type of machine-made wig where the hair is woven into "wefts". Unlike a cap wig, which has a solid cap that covers the entire head, a capless wig has open spaces between the wefts, allowing for better ventilation and a lighter weight. This design makes the wig more comfortable to wear, especially in hot weather. The term "capless" refers to the absence of a solid cap, resulting in a more breathable and lightweight wig option.

The sebaceous glands produce sebum and oil. Sebum is an oily substance that helps to lubricate the skin and hair, keeping them moisturized. It also helps to protect the skin from drying out and acts as a barrier against bacteria and other harmful substances. Oil, on the other hand, is a general term used to describe any lipid-based substance that is produced by the sebaceous glands. Both sebum and oil play important roles in maintaining the health and integrity of the skin.

The sudoriferous glands produce sweat and perspiration, which both help in heat regulation. Sweat helps to cool down the body by evaporating from the skin, while perspiration also aids in regulating body temperature. Additionally, sweat acts as a lubricant for the skin, preventing friction and chafing. Therefore, both options B and C are correct.

The correct answer is spiral. A spiral perm wrap/curling iron set is designed to create a uniform curl from the scalp to the ends of the hair. This type of perm wrap/curling iron set creates spiral-shaped curls that are consistent throughout the hair.

When creating a pin curl, you start at the open end. This is the end of the hair section that is not secured by any clips or pins. Starting at the open end allows you to wrap the hair smoothly around your finger or roller, creating a neat and even curl. It also ensures that the curl will hold securely in place once it is pinned.

The term "the law of color" refers to a system that helps in understanding the relationships of color. This system provides guidelines and principles for combining and using colors effectively. It encompasses various aspects such as color harmonies, color psychology, and color symbolism. By following the law of color, artists, designers, and other individuals can create visually appealing and harmonious color schemes for various purposes.

A solution is a stable mixture of two or more substances that are mixed together and will not separate upon standing. In a solution, the solute particles are evenly distributed throughout the solvent, resulting in a homogeneous mixture. This is different from a suspension, where the particles are larger and will eventually settle out, or an emulsion, where two immiscible liquids are mixed together but can separate over time. A colloid is a type of mixture where the particles are larger than those in a solution but smaller than those in a suspension, and they do not settle out upon standing.

A suspension is an unstable mixture of two or more substances that will separate upon standing. In a suspension, the particles of one substance are dispersed in another substance, but they are not completely dissolved. Instead, they remain suspended in the mixture and can be seen with the naked eye. Over time, the particles will settle at the bottom due to gravity, causing the mixture to separate. This is different from a solution, where the solute is completely dissolved in the solvent, and from an emulsion, where two immiscible liquids are mixed together. A colloid, on the other hand, is a stable mixture where the particles are evenly dispersed and do not settle.

The most popular/common type of permanent wave tool used is concave. This is because concave tools are designed to create curls and waves in the hair, making them ideal for achieving the desired results in a permanent wave. The curved shape of the concave tool allows for better control and manipulation of the hair, resulting in more defined and long-lasting waves.

Metallic salts found in at-home hair-coloring products can darken the hair gradually with repeated usage. However, they are incompatible with permanent wave preparation and other chemical services. This means that using metallic salts may result in hair breakage, hair discoloration, and uneven curl formation. The one thing they will not cause is overly tight curl formation.

Telogen is known as the "resting stage" of hair growth. During this phase, the hair follicle is in a dormant state and does not produce new hair. This stage lasts for about 2-3 months before the hair follicle enters the next phase of growth called anagen. During anagen, new hair starts to grow from the follicle. Halogen, catagen, and anagen are not associated with the resting stage of hair growth.

A straight perm rod tool produces a uniform curl throughout the hair because it has a consistent diameter from top to bottom. This allows the hair to wrap around the rod evenly, resulting in a consistent curl pattern. In contrast, convex, concave, and spiral perm rods have varying diameters, which can create different curl patterns and variations in the final result.

The dermis is the correct answer because it is the layer of the skin that contains the most blood vessels. These blood vessels supply oxygen and nutrients to the skin cells, and help regulate body temperature. The dermis also contains other important structures such as hair follicles, sweat glands, and nerve endings.

The correct answer is A and C, which means that the HIV virus is primarily spread through unprotected sexual contact and food preparation. Unprotected sexual contact is a common mode of transmission for HIV, as the virus can be present in semen, vaginal fluids, and blood. Food preparation can also be a source of transmission if contaminated with HIV-infected blood or other bodily fluids. However, intravenous (IV) drug use is also a significant mode of transmission for HIV, but it is not included in the correct answer.

A wood's lamp is a filtered black light that is used to illuminate various skin disorders, bacterial disorders, fungi, and pigmentation. It emits ultraviolet light, which causes certain substances in the skin to fluoresce or appear differently under the light. This can help in diagnosing conditions such as fungal infections, vitiligo, and melasma. The other options, halogen light, Fitzpatrick scale, and Murad lamp, do not specifically refer to a filtered black light used for skin examination.

The correct answer is anagen. Anagen is the longest stage of hair growth. During this stage, the hair follicle is actively producing new cells and the hair is growing. This stage can last for several years, depending on factors such as genetics and overall health.

Applying more lightener is the correct answer because if dark spots remain on the hair shaft after removing the lightener, it indicates that the initial application was not sufficient to lighten those areas. By applying more lightener, it will help to further lighten the dark spots and achieve a more even color result.

During the growth stage of hair, also known as the anagen phase, the hair follicles actively produce new hair. This phase can last anywhere between 1 to 7 years. After this phase, the hair enters a resting phase called the telogen phase, where it stops growing and eventually falls out. The length of the growth stage can vary depending on factors such as genetics, age, and overall health.

Vertical lines are used to make a hairstyle appear longer and narrower. When hair is styled using vertical lines, it creates an illusion of length and slimness. This is because vertical lines draw the eyes upward and downward, creating a sense of elongation. By using vertical lines in the design of a hairstyle, the overall shape and silhouette can be manipulated to make it appear longer and narrower.

Over-processed hair is usually curly at the roots and straight at the ends. This is because the chemicals used during the hair processing, such as relaxers or perms, can weaken the hair structure and alter its natural texture. As a result, the roots, which are closer to the scalp and receive more exposure to the chemicals, become curly. On the other hand, the ends, which are older and have been subjected to more damage over time, may appear straighter. This difference in texture between the roots and ends is a common characteristic of over-processed hair.

Cutting a wig is best performed on dry hair because wet or damp hair can stretch and change shape when it dries, leading to an inaccurate haircut. Additionally, cutting a wig on the client's head can be difficult as it may not provide a stable and consistent surface for precise cutting. Therefore, dry hair is the ideal condition for cutting a wig as it allows for more control and accuracy in achieving the desired haircut.

A wig is a hair-piece that covers the top and back of the head, and is used to add length to one's hair. It is a common accessory for individuals who want to change their hairstyle or add volume to their natural hair. Wigs are available in various styles, colors, and lengths, allowing people to experiment with different looks without permanently altering their own hair.

The lacrimal bones are small thin bones located at the front, inner walls of the orbits. They are responsible for forming a part of the eye socket and housing the tear ducts. The malar bones, also known as the cheekbones, are not located at the front, inner walls of the orbits. The zygomatic bones, also known as the cheekbones, are not located at the front, inner walls of the orbits. The hyoid bones are located in the neck and are not associated with the orbits.

Depilation refers to the process of removing hair at the surface of the skin. It involves removing hair from the skin's surface without affecting the hair follicle. Waxing, epilation, and electrolysis all involve removing hair from the root or affecting the hair follicle in some way, whereas depilation specifically refers to surface hair removal.

The cortex is composed of millions of polypeptide bonds cross-linked by three types of side bonds. This suggests that the cortex is the structure that contains these bonds, making it the correct answer.

Under-processed hair is usually straight at the roots and curly at the ends. This is because the natural texture of the hair is not evenly distributed throughout the strands. When the hair is under-processed, it means that the chemical treatment or heat styling has not fully penetrated the hair shaft, resulting in a lack of uniformity in the hair's texture. As a result, the roots, which are closer to the scalp and receive more natural oils, tend to be straighter, while the ends, which are older and more exposed to external factors, become more curly or frizzy.

The primary purpose of a scalp treatment is to maintain the scalp and hair in a clean and healthy condition. This includes removing any oil accumulation from the follicles, stimulating blood flow to the hair follicle, and prolonging the anagen stage while diminishing the catagen stage. By keeping the scalp clean and healthy, it promotes overall hair health and growth.

The given answer states that the most expensive type of human hair for wigs is European hair, followed by Indian and Asian hair mixed with yak/horse hair. This implies that European hair is considered the highest quality and therefore commands a higher price in the market. Indian and Asian hair mixed with yak/horse hair is ranked second in terms of pricing, suggesting that it is of slightly lower quality but still more expensive than other options.

The zygomatic and malar bones form the prominence of the cheeks. The zygomatic bone, also known as the cheekbone, is a paired bone that contributes to the lateral wall and floor of the orbit, as well as the prominence of the cheek. The malar bone, also known as the cheekbone or zygomatic bone, is a paired bone that forms the prominence of the cheeks and contributes to the lateral wall and floor of the orbit. Together, these bones give the face its characteristic shape and structure.

The correct answer is B & C. This means that both options B and C are correct. The normal elasticity of dry hair is approximately 1/5th or 20%.

The elasticity test, also known as the pull test, is used to determine the hair's suitability to receive a permanent treatment. This test involves gently pulling a strand of hair to see how much it stretches and returns to its original length. Hair with good elasticity is more likely to withstand the chemical process of a permanent treatment without breaking or becoming damaged. Therefore, the elasticity test is an important step in determining if the hair is strong and healthy enough to undergo a permanent treatment.

The perm tool in #399 will produce a curl that is tighter at the center and ends as well as tighter at the sides and scalp. This means that the curl will be more defined and compact both in the middle and at the sides of the hair, resulting in a tighter overall curl pattern.

During the permanent wave process, chemical changes occur in the hair. These changes can affect the elasticity of the hair, making it important to perform an elasticity test before perming the hair. This test helps determine the hair's ability to stretch and return to its original shape without breaking. By conducting an elasticity test, stylists can assess the hair's condition and determine if it is suitable for the perming process. This ensures that the hair will not be damaged during the treatment and helps achieve desired results.

During a preliminary test curl procedure, it is important to wrap the tools in different areas of the head to ensure an even and balanced result. The top and side sections are commonly chosen, and the occipital area is another crucial area to include. The occipital refers to the back of the head, specifically the lower part where the skull curves inward. By wrapping a tool in this area, it helps to create a well-rounded and uniform curl pattern throughout the entire head.

The neutralization step in hair treatment is primarily focused on rebuilding disulfide bonds. These bonds are responsible for the hair's strength and structure. Rebuilding hydrogen bonds, on the other hand, is not a function of the neutralization step. Hydrogen bonds are weaker and temporary bonds that contribute to the hair's elasticity and manageability. While hydrogen bonds may be affected during the treatment process, they are not specifically targeted for rebuilding in the neutralization step.

The correct answer is cuticle and cortex. The side bonds in the hair are found in the cuticle and cortex layers. The cuticle is the outermost layer of the hair shaft, consisting of overlapping scales that protect the inner layers. The cortex is the middle layer, which contains the protein structures that give the hair its strength, elasticity, and color. These side bonds, such as hydrogen bonds and disulfide bonds, help to maintain the hair's structure and shape.

The croquignole perm wrap or curling iron set is known for producing a curl that is looser at the scalp and tighter at the ends. This technique involves wrapping the hair around the curling iron in a spiral fashion, starting from the ends and moving towards the scalp. As a result, the curl is tighter at the ends where the hair was wrapped first, and looser at the scalp where the hair was wrapped last. This creates a natural-looking curl with more volume and movement.

The half stem pin-curl allows for the greatest movement and mobility because it is positioned halfway between the base and the ends of the hair strand. This placement allows the hair to have some support and structure from the base, while still allowing the ends to move freely. This type of pin-curl is ideal for creating volume and soft waves in the hair.

The correct answer is "fallen" because hair that has fallen naturally from the scalp generally has its cuticle moving in opposite directions, making it more likely to tangle, mat, and lock. Due to this, the cuticle is often removed from fallen hair to prevent these issues.

Decolorizing products are used to remove or lighten hair color, and they do not typically require a patch test prior to the service. Patch tests are usually done for products that have a higher risk of causing allergic reactions or skin sensitivities. While decolorizing products can be harsh on the hair and scalp, they are not typically known to cause allergic reactions, unlike aniline derivative products which can be more irritating to the skin. Therefore, the use of decolorizing products does not require a patch test.

Side bonds, also known as disulfide bonds, are responsible for the elasticity of the hair. These bonds are formed between sulfur atoms in the protein structure of the hair. They provide strength and flexibility to the hair, allowing it to stretch and return to its original shape. When the side bonds are intact, the hair has good elasticity and can withstand styling and manipulation without breaking. However, if these bonds are damaged or broken, the hair becomes weak and brittle, losing its elasticity. Therefore, side bonds play a crucial role in maintaining the elasticity of the hair.
