Which hair portion absorbs chemical wave solution faster?
Correct Answer
C. Where hair porosity is greatest
Explanation
Hair porosity refers to the ability of hair to absorb and retain moisture and chemicals. When it comes to a chemical wave solution, the portion of hair with the highest porosity will absorb the solution faster compared to other areas. This is because high porosity hair has a more open cuticle layer, allowing the solution to penetrate more easily. Therefore, the correct answer is where hair porosity is greatest.
2.
How is the hair if the cuticle is slightly raised and accepts color products easily?
Correct Answer
A. Normal
Explanation
If the cuticle is slightly raised and accepts color products easily, it indicates that the hair is in a healthy condition. The cuticle is the outermost layer of the hair shaft and acts as a protective barrier. When the cuticle is raised, it allows color products to penetrate easily, resulting in better color absorption. This is typically seen in normal hair, which is neither too fine nor too coarse. Resistant hair would have a tightly closed cuticle, making it difficult for color products to penetrate. Fine hair would have a very thin cuticle, while coarse hair would have a thick and rough cuticle.
3.
How should the hair be before giving a chemical wave?
Correct Answer
D. It should be analyzed and shampooed
Explanation
Before giving a chemical wave, the hair should be analyzed and shampooed. This is important because analyzing the hair helps to determine its condition and the appropriate products and techniques to use during the chemical wave process. Shampooing the hair beforehand removes any dirt, oil, or product buildup, ensuring that the chemicals can penetrate the hair effectively. This step also helps to create a clean and healthy foundation for the chemical wave, resulting in better results and minimizing potential damage to the hair.

In cosmetology, which ingredient is primarily responsible for the oxidizing action in hair coloring products that enables the hair dye to develop and bind to the hair?
Correct Answer
B. Hydrogen peroxide
Explanation
Hydrogen peroxide is the key oxidizing agent used in many hair coloring products. Its primary role is to open the cuticle of the hair so that the dye can penetrate into the cortex. Once inside, hydrogen peroxide helps to initiate the chemical reaction that leads to the development of color molecules, which are then bound within the hair fiber. This action not only allows for permanent color changes but also ensures the longevity of the color in the hair.
6.
Which of the following determines the texture of the hair?
Correct Answer
C. Diameter
Explanation
The texture of the hair is determined by its diameter. Hair can have a fine or coarse texture depending on the thickness of its individual strands. Fine hair has a smaller diameter, while coarse hair has a larger diameter. The diameter of the hair affects how it feels and behaves, such as how easily it can be styled or how prone it is to frizz. Porosity, elasticity, and density are other factors that can affect the condition and appearance of the hair, but they do not directly determine its texture.
7.
What will it do if a temporary color rinse is applied to normal hair?
Correct Answer
A. Coat the cuticle layer
Explanation
If a temporary color rinse is applied to normal hair, it will coat the cuticle layer. This means that the color rinse will create a layer on the outermost part of the hair shaft, which is the cuticle. This coating will temporarily change the color of the hair without penetrating deeper layers such as the medulla.
8.
Why is it necessary to apply an antiseptic to tweezed areas during arching?
Correct Answer
C. To avoid infection
Explanation
Applying an antiseptic to tweezed areas during arching is necessary to avoid infection. When tweezing, the hair follicles are being pulled out, creating tiny open wounds on the skin. These open wounds can easily become a breeding ground for bacteria, leading to infections. By applying an antiseptic, it kills or inhibits the growth of bacteria, reducing the risk of infection and promoting proper healing of the skin.

14.
What tendency does the hair have during the processing time in chemical waving?
Correct Answer
A. To expand
Explanation
During the processing time in chemical waving, the hair tends to expand. This is because the chemical solution used in the process breaks down the protein bonds in the hair, allowing it to be reshaped. As the bonds are broken, the hair becomes more flexible and expands, allowing it to take on the desired shape or curl.
15.
It is made of cells, blood, calcium carbonate, and calcium phosphate?
Correct Answer
C. Bones
Explanation
Bones are made up of cells, blood vessels, and minerals such as calcium carbonate and calcium phosphate. These minerals give bones their strength and hardness. Nerves, on the other hand, are not made up of cells, blood, or these specific minerals. Teeth also contain calcium phosphate, but they do not have blood vessels or cells. Tendons are made up of collagen fibers and do not contain cells, blood, or these minerals. Therefore, bones are the only option that fits all the given components.
16.
Disulfide bonds are broken by the:
Correct Answer
C. Chemical wave solution
Explanation
Chemical wave solutions are used in hair perming processes to break the disulfide bonds in the hair. These bonds are responsible for the hair's natural shape and structure.

Lightened hair requires the shortest processing time in chemical waving because it has already undergone a chemical process to lighten the color. The hair cuticles are more porous and receptive to chemical treatments, allowing for faster and more effective processing. Fine, coarse, and resistant hair types may require longer processing times as they are less porous and may require more time for the waving solution to penetrate and reshape the hair structure.
21.
What may frequent shampooing with highly alkaline shampoo cause the hair to become?
Correct Answer
A. Dry
Explanation
Frequent shampooing with highly alkaline shampoo can cause the hair to become dry. 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 breakage of the hair strands. It is important to use a shampoo that is pH balanced and suitable for your hair type to maintain its health and moisture.
22.
Which layer of the skin is primarily responsible for producing new skin cells?
Correct Answer
A. Epidermis
Explanation
The epidermis is the outermost layer of the skin and is primarily responsible for producing new skin cells. This layer continuously generates new cells through a process called keratinization. The cells in the epidermis move up to the surface, where they eventually shed off, allowing for the renewal of the skin. The dermis and subcutaneous layer (hypodermis) provide structural support and insulation but do not produce new skin cells.
23.
What should be done to protect a sensitive scalp during a relaxer treatment?
Correct Answer
A. Apply a protective base.
Explanation
To protect a sensitive scalp during a relaxer treatment, it is important to apply a protective base. This is because a relaxer treatment involves the use of chemicals that can be harsh on the scalp and cause irritation or burns. Applying a protective base creates a barrier between the scalp and the relaxer, minimizing the risk of damage. It is not necessary to use a mild shampoo or apply a conditioner during the relaxer treatment, as their main purpose is to cleanse and condition the hair, not protect the scalp. Using an astringent on the scalp is also not recommended, as it can further irritate the sensitive skin.
24.
High elevation in hair cutting is used for what?
Correct Answer
C. Create layers
Explanation
High elevation in hair cutting is used to create layers. When cutting hair with high elevation, the hair is lifted away from the head and cut at an angle, resulting in shorter layers on top and longer layers underneath. This technique adds movement and texture to the hair, creating a layered look. It is commonly used to add volume and dimension to the hair, giving it a more dynamic and versatile style.
