Chemical texture services refer to hair services that involve the use of chemicals to permanently alter the natural wave pattern of the hair. This can include procedures such as relaxing, perming, or straightening the hair using chemical treatments. Thermal waving, wet setting, and hair coloring services do not involve permanent alteration of the hair's wave pattern, making chemical texture services the correct answer.

The correct answer is "coarse, medium, and fine". Hair texture can be described using these terms because they refer to the thickness or diameter of individual hair strands. Coarse hair is thick and has a larger diameter, while fine hair is thin and has a smaller diameter. Medium hair falls in between these two categories. This classification helps in understanding the overall appearance and behavior of different hair types.

The second part of any perm involves the application of waving solution and neutralizer. These chemicals work together to break and reform the disulfide bonds in the hair, which results in a permanent change in the hair's structure. This process is a chemical change because it involves the breaking and forming of new chemical bonds.

A bookend wrap is a technique used in hair styling where one end paper is folded in half over the hair ends, resembling the way an envelope is folded. This technique helps to secure the hair ends and create a neat and polished look. It is called a bookend wrap because the folded end paper resembles the shape of a bookend, which is used to support and hold books upright on a shelf.

The correct answer is "piggyback wrap". The piggyback wrap is another term used to refer to the double tool perm technique. This technique involves wrapping two rods together, with one rod piggybacking on top of the other. It is a common method used in perming to create a variety of curl patterns and textures in the hair.

Coarse hair is typically harder to penetrate when treated with chemical texture services. This is because coarse hair has a thicker and more tightly packed cuticle layer, making it more resistant to chemical penetration. As a result, it may require more time and effort to achieve the desired results when treating coarse hair with chemical services.

The size of the perm tool determines the size of the curl. The larger the perm tool, the larger the resulting curl will be. Conversely, a smaller perm tool will create smaller curls. The size of the perm tool does not affect the base control, placement of the curl, or base direction.

End wraps are absorbent papers used when winding hair on perm tools to control the hair ends. By wrapping the hair ends with these papers, they provide a barrier between the hair and the perm tool, preventing any loose ends from unraveling during the perming process. This helps in achieving a more uniform and controlled curl or wave pattern.

Rods with the same circumference along their entire length or curling area are called straight rods. This means that the rods have a consistent thickness or width from end to end, without any tapering or curvature. They are completely straight and do not have any convex or concave shape.

A strong, compact cuticle refers to the outermost layer of the hair shaft being healthy and intact. This means that the hair is less prone to damage from external factors such as heat, chemicals, or environmental stressors. It also implies that the hair is less likely to absorb moisture or lose moisture, making it resistant to becoming dry or frizzy. Therefore, a strong, compact cuticle contributes to having resistant hair.

Fine hair is the most fragile and easiest to process with permanent waving solution because it has a smaller diameter and is more delicate compared to other hair textures. The smaller diameter makes it more susceptible to damage from chemical treatments, such as permanent waving. Additionally, fine hair has a lower density, which allows the waving solution to penetrate and process more quickly. This makes it easier to achieve the desired wave or curl pattern in fine hair compared to other hair textures.

Wet hair with normal elasticity can stretch up to 50 percent of its original length and then return to that length without breaking. This means that when wet, the hair can be stretched to half of its original length and still retain its elasticity, allowing it to bounce back to its original length without any damage or breakage.

The first part of a perm, which involves wrapping the hair on perm rods, causes a physical change. This is because the hair is being manipulated and reshaped into a new form, but there is no alteration to the chemical composition of the hair or its bonds. The physical change is temporary and can be reversed by washing or applying heat to the hair.

Perm solution should be rinsed from the hair for at least five minutes. This is because rinsing the hair for a sufficient amount of time helps to remove any residual chemicals from the perm solution, reducing the risk of damage to the hair and scalp. Rinsing for a shorter duration may not effectively remove all the chemicals, while rinsing for a longer duration may lead to overexposure and potential harm to the hair.

Porous, damaged, or chemically treated hair is already in a weakened state and using a high pH or more alkaline perm solution can further damage the hair. Therefore, a perm solution that is less alkaline is recommended for such hair types. This solution will be milder and gentler on the hair, minimizing the risk of further damage.

The double flat wrap technique provides the most control over the hair ends and keeps them evenly distributed. This technique involves folding the end paper in half and placing it flat against the hair ends, then folding another end paper in half and placing it flat on top of the first end paper. This double layer of end paper helps to secure the hair ends in place and prevent them from sticking out or becoming unevenly distributed during the wrapping process.

After rinsing the perm solution from the hair, the next step is to blot the rods with towels. This is done to remove any excess moisture from the hair and the rods, ensuring that the hair sets properly and the desired wave or curl pattern is achieved. Blotting the rods with towels also helps to prevent any dripping or running of the perm solution, which could potentially cause uneven results or damage to the hair. Once the rods are blotted, the next step would typically be to apply the neutralizer to set the hair in its new shape.

Disulfide bonds are the strongest type of side bonds. These bonds are formed when two cysteine amino acids come together and form a covalent bond between their sulfur atoms. Disulfide bonds are very stable and require a significant amount of energy to break. They play a crucial role in maintaining the structure and stability of proteins, such as in the formation of the tertiary structure. Therefore, among the three types of side bonds, disulfide bonds are the strongest.

In permanent waving, the processing time refers to the amount of time it takes for the solution to effectively change the structure of the hair. The correct answer, 5 to 10 minutes, suggests that the majority of this process occurs within this time frame. This indicates that the solution is able to penetrate the hair and initiate the desired chemical reaction within the first 5 to 10 minutes.

Chemical hair relaxing is the process of rearranging the basic structure of extremely curly hair into a straight form. This is achieved by using chemical products that break down the hair's protein structure and then reforming it into a straight shape. Thermal hair relaxing, on the other hand, involves using heat styling tools to temporarily straighten the hair. Chemical hair waving is a process used to create curls or waves in the hair, while permanent waving is a technique used to create long-lasting curls.

A wet set is an example of a physical change because it involves temporarily altering the shape or texture of the hair using water and styling products, but does not involve any chemical reactions or permanent changes to the hair structure.

Circle tools or loop rods are ideal for spiral wrapping very long hair. This is because spiral wrapping involves creating a spiral shape with the hair, and circle tools or loop rods are specifically designed to help achieve this shape. They provide a larger surface area for the hair to wrap around, making it easier to create defined and uniform spirals in long hair. Additionally, the size and shape of circle tools or loop rods are not suitable for wrapping small sections or croquignole wrapping short hair, as these techniques require smaller tools for better control and precision.

Rods with a smaller circumference in the center than at the ends are called concave rods. This is because the term "concave" refers to a surface or shape that curves inward or has a hollowed-out appearance. In the case of these rods, the center is narrower or hollowed out compared to the ends, creating a concave shape.

Soft bender rods are unique because they have the ability to be bent into various shapes. Unlike other types of rods, they offer flexibility and can be molded according to the desired hairstyle. This feature allows for versatile styling options, making them suitable for creating different types of curls and waves. Whether it's a loose wave, tight spiral, or any other shape, soft bender rods can be easily manipulated to achieve the desired look.

The natural wave pattern of the hair is determined by the side bonds in the hair structure. By breaking these side bonds, it is possible to change the natural wave pattern of the hair. Peptide bonds are responsible for the formation of protein structures, not the wave pattern of the hair. End bonds and polypeptide chains are not relevant to the wave pattern of the hair.

Ammonium thioglycolate is produced by adding ammonia to thioglycolic acid. Ammonia reacts with thioglycolic acid to form ammonium thioglycolate.

Hair that has just been permed may be colored with demipermanent haircolor because demipermanent haircolor does not contain ammonia or peroxide, which can further damage the hair. It is a gentler option that can add color and shine to the hair without causing additional irritation to the scalp.

Hydrogen bonds, although individually weak, play a significant role in the overall strength of hair. These bonds form between the hydrogen atoms of one hair strand and the oxygen or nitrogen atoms of another strand. Due to the large number of hydrogen bonds present in hair, they collectively contribute to approximately one-third of its total strength. Therefore, the correct answer is 1/3.

Off-base placement creates the least amount of volume among the various base controls. This technique involves wrapping the hair around the base of the tool, away from the scalp. Since the hair is not wrapped tightly against the scalp, it does not create as much lift or volume as the other placement options. On-base placement, croquignole placement, and half-off-base placement all involve wrapping the hair closer to the scalp, which creates more volume.

The spiral perm technique is a method of perming hair that involves using two tools on one strand of hair. This technique is known for producing a uniform curl from the scalp to the ends of the hair. It is particularly well-suited for short hair and follows the curvature of the head, resulting in a natural and even curl pattern.

Relaxers and permanents change the shape of the hair by breaking disulfide bonds. Disulfide bonds are strong chemical bonds that hold the structure of the hair together. By breaking these bonds, the hair can be reshaped or straightened. This process is typically achieved by using chemicals that break the disulfide bonds and then reform them in a new shape.

Salt bonds are formed between positively and negatively charged ions in a molecule. These bonds are relatively weak and can be easily broken when the pH of the environment changes. When the pH changes, the concentration of hydrogen ions in the solution alters, which affects the charge distribution in the molecule and weakens the salt bonds. This makes changes in pH the most likely factor to break salt bonds.

When hair is wrapped on small tools, it increases the tension on the hair strands. This tension causes the hair to stretch and conform to the shape of the tool, resulting in a larger curl size. Therefore, the correct answer is tension.

If the hair is underprocessed, it means that too few disulfide bonds are broken. Disulfide bonds are responsible for the shape and structure of the hair. When these bonds are broken, it allows the hair to be reshaped or styled. If too few bonds are broken, it means that the hair hasn't been processed enough to achieve the desired result. This can result in the hair not being as soft or as curly as intended.

Metallic salts, when left on the hair, can cause severe discoloration, hair breakage, or uneven curls. This is because metallic salts can react with other chemicals in hair products or with the natural compounds in the hair, resulting in an unpredictable and uneven curl pattern. The coating left by metallic salts can disrupt the hair's natural texture and structure, leading to irregular and inconsistent curls.

In hair analysis for chemical texture services, growth direction is an important factor to consider. This is because the direction in which hair grows can affect the outcome of the chemical treatment. The growth direction can determine how the chemicals will interact with the hair, and it can also impact the overall look and style of the hair after the treatment. Therefore, understanding the growth direction is crucial in order to achieve the desired results in chemical texture services.

A single flat wrap is when one end paper is placed over the top of the hair strand as it is wrapped around the perm tool. This technique helps to create a smooth and even curl pattern.

Alkaline waves, also known as cold waves, are a type of permanent wave solution used in hair styling. They are called cold waves because they do not require heat to set the hair, unlike other types of permanent waves. Instead, alkaline waves use a chemical process to break and reform the disulfide bonds in the hair, resulting in a new curl pattern. This term is commonly used in the hairdressing industry to differentiate alkaline waves from other types of permanent waves that may use different pH levels or ingredients.

Permanent waves that require heat from an outside source, usually a hair dryer, are called endothermic. Endothermic waves are a type of permanent wave that require the application of heat to activate the waving lotion or solution. The heat helps to open up the hair cuticle, allowing the waving solution to penetrate and reshape the hair. This type of permanent wave is typically used for clients with resistant or coarse hair, as the heat helps to break down the protein structure of the hair, allowing for a more effective and longer-lasting curl.

In off-base placement, the hair is wrapped 45 degrees below perpendicular to its base section. This means that the hair is wrapped at an angle that is below the 90-degree angle formed by the base section. This technique is commonly used in hair styling to create volume and movement in the hair. By wrapping the hair at a downward angle, it allows the hair to fall in a natural and flowing manner.

Elasticity is the ability of hair to stretch and return to its original shape without breaking. It is the most important factor in determining the ability of hair to hold a curl because hair that is more elastic will be able to stretch and conform to the shape of the curling iron or other styling tool, and then bounce back into a curled shape. Hair that lacks elasticity may not be able to hold a curl as well because it may not be able to stretch and conform to the shape of the curling iron, resulting in a looser or less defined curl.

The curvature perm wrap is the correct answer because it is the perm wrap technique that creates a movement that curves within sectioned-out panels. This technique is used to add volume and create natural-looking waves or curls in the hair. The other options, such as the weave technique, straight perm wrap, and bricklay perm wrap, do not specifically create this type of curved movement within sectioned-out panels.

Zigzag partings are used in the weave technique of perm wrapping. This technique involves dividing the base areas of the hair into zigzag sections and wrapping the perm rods in a crisscross pattern. The zigzag partings create a more natural and blended look, as they allow the hair to fall in a more random pattern, rather than in uniform rows. This technique is commonly used to achieve a more textured and voluminous result in perming.

Ammonia is used to test for metallic salts in the hair because it forms a complex with the metal ions present in the salts. This complex usually has a distinct color, allowing for easy identification of the presence of metallic salts. Peroxide is typically used as a bleaching agent in hair treatments, and thio is not commonly used in this context. Alcohol does not have the ability to form complexes with metallic salts, making it an ineffective choice for testing.

A wet set and a perm both involve curling the hair, but the major difference lies in the type of bonds broken. In a wet set, the curls are achieved by breaking the hydrogen bonds in the hair, which can be easily reformed when wet. On the other hand, a perm breaks the stronger disulfide bonds in the hair, which permanently alters the hair's structure and allows it to hold the curl even when dry. Therefore, the correct answer is "type of side bonds broken."

Perm wrapping involves dividing the hair into panels, which are then further divided into base sections. Base sections are the subsections of each panel where the hair is wrapped around the perm rod. This allows for even distribution of the perm solution and creates consistent curls or waves throughout the hair.

Croquignole wrapping is the wrapping technique in which the hair is wrapped from the ends to the scalp in overlapping layers. This technique creates a tighter curl and is commonly used for creating spiral curls or waves. Basic wrapping involves wrapping the hair in a single layer from the ends to the scalp, while spiral wrapping involves wrapping the hair in a spiral pattern from the ends to the scalp. Circular wrapping refers to wrapping the hair in a circular pattern around the head.

The neutralizer in this context is responsible for deactivating any remaining waving solution in the hair and rebuilding broken disulfide bonds. Disulfide bonds are responsible for the hair's structure and strength, and during the waving process, these bonds are broken to reshape the hair. The neutralizer helps to reform these bonds, ensuring that the hair retains its desired shape and strength. Conditioning the hair and re-forming broken hydrogen bonds are not mentioned as functions of the neutralizer in this question. Breaking remaining disulfide bonds would not be desirable as it would weaken the hair further.

Applying a pre-neutralizing conditioner after blotting the hair helps to prepare the hair for the neutralizer. This conditioner helps to restore moisture and balance the pH levels of the hair, ensuring that it is in the best condition to receive the neutralizer. By applying the pre-neutralizing conditioner, the hair is protected from potential damage that the neutralizer may cause, and it also helps to enhance the effectiveness of the neutralizing process.
