Question 1
Which of the following is a characteristic of Guanidine hydroxide compared to other relaxers?
Correct Answer:
Requires a two-part application
Explanation:
Guanidine hydroxide is distinctive in its application process, requiring a two-part application. This characteristic is significant because it involves the use of two separate components that are mixed together before application to the hair. This dual-component system helps to create a more effective and stable product, allowing for a smoother and more manageable relaxer service. In contrast to many single-component relaxers, this two-part system enables hairstylists to have more control over the chemical reaction and the overall relaxation process. This can be particularly beneficial for clients with varying hair textures and conditions, allowing for tailored services.
Question 2
What are peptide bonds also known as?
Correct Answer:
End bonds
Explanation:
Peptide bonds are also known as end bonds because they are the specific type of bond that links amino acids together to form proteins. These bonds are essential in the structure of the hair, as they provide the primary link necessary for the formation of polypeptide chains, which are fundamental components of hair and skin structures. Understanding peptide bonds as end bonds highlights their role in creating the protein chains that ultimately contribute to the overall strength and integrity of hair. The term "end bonds" directly refers to how these bonds connect the terminal ends of amino acids in a chain, facilitating the formation of complex protein structures.
Question 3
What is the effect of applying too much neutralizer?
Correct Answer:
Over-processed hair
Explanation:
The effect of applying too much neutralizer during a chemical texture service leads to over-processed hair. Neutralizers are essential in the perming process as they help to halt the wave formation and lock the curls in place. However, when an excessive amount is applied, it can overly strengthen the disulfide bonds in the hair, causing the cuticle to become extremely tight. This can result in a range of issues, including brittleness, excessive dryness, and a compromised structural integrity of the hair, ultimately leading to breakage. Additionally, over-processing can strip the hair of its natural moisture and oils, making it appear dull and damaged. It's important to use the correct amount of neutralizer to achieve the desired curl pattern without compromising the hair's health. Each hair type and texture may require a different level of neutralization, which is why careful attention to the product application is crucial in chemical services.
Question 4
In which layer of hair are polypeptide chains cross-linked by side bonds?
Correct Answer:
Cortex
Explanation:
The cortex is the correct answer because it is the middle layer of the hair shaft and plays a critical role in the hair's overall strength and elasticity. Polypeptide chains, which are the primary structure of proteins, are found in the cortex, and these chains are organized into long fibers. In the cortex, these polypeptide chains are interconnected by various types of side bonds, including hydrogen bonds, salt bonds, and disulfide bonds. These side bonds are essential for maintaining the structure and integrity of the hair, influencing characteristics like texture, curl, and resilience. The medulla, being the innermost layer of the hair, typically does not contribute to hair's structure in terms of polypeptide chains or side bonds. The cuticle, the outer layer, serves as a protective barrier rather than a structure where polypeptide chains are cross-linked. Lastly, the follicle is not a part of the hair shaft; it is the structure from which the hair grows and doesn't contain the polypeptide chains or side bonds relevant to the question.
Question 5
What is a primary benefit of using Guanidine hydroxide in hair relaxers?
Correct Answer:
Reduces scalp irritation
Explanation:
Guanidine hydroxide is a key ingredient used in no-lye hair relaxers, and one of its primary benefits is its ability to reduce scalp irritation. Traditional lye relaxers, which contain sodium hydroxide, can be quite harsh on the scalp and skin, often leading to discomfort, redness, and irritation. Guanidine hydroxide, on the other hand, offers a gentler alternative, making it suitable for clients with sensitive skin or those who have experienced irritation with lye relaxers. In addition to its milder nature, guanidine hydroxide effectively alters the hair's structure to relax curls and waves. This component allows stylists to provide soothing and less damaging treatments, resulting in a more comfortable experience for clients during the relaxation process. By prioritizing scalp health, this ingredient enhances the overall quality of the chemical service. While the other options may address certain aspects of hair care or styling, they do not reflect the primary attributes of guanidine hydroxide as effectively as its ability to minimize scalp irritation.
