Most relaxers contain the same ingredients used in:
- A.
Permanent haircolors
- B.
Temporary haircolors
- C.
Depilatories
- D.
Epilators
Correct Answer
C. DepilatoriesExplanation
Most relaxers contain the same ingredients as depilatories. Depilatories are products used to remove hair from the skin's surface by breaking down the protein structure of the hair. Similarly, relaxers contain chemicals that break down the protein bonds in the hair, allowing it to be straightened. Therefore, the ingredients used in depilatories are also used in relaxers to achieve the desired effect of straightening the hair.Rate this question:

Extremely curly hair:
- A.
Has a uniform diameter
- B.
Has varying diameters
- C.
Is very strong
- D.
Is thickest at the twist
Correct Answer
B. Has varying diametersExplanation
Extremely curly hair has varying diameters because the curls and coils in the hair cause the strands to bend and twist, resulting in sections of the hair being thicker or thinner than others. This variation in diameter gives curly hair its unique texture and appearance.Rate this question:

Extremely curly hair is weakest at the:
- A.
Midshaft
- B.
Base
- C.
Ends
- D.
Twist
Correct Answer
D. TwistExplanation
Extremely curly hair is weakest at the twist because the twisting motion puts strain on the hair strands, causing them to become more prone to breakage. This is especially true for tightly coiled or kinky hair textures, where the hair shafts are tightly wound and more susceptible to damage when twisted. Therefore, the twist is the weakest point in extremely curly hair.Rate this question:

Thio relaxers:
- A.
Have a ph above 10
- B.
Use less ATG than in perming
- C.
Harden the hair
- D.
Do not use a reducing agent
Correct Answer
A. Have a pH above 10Explanation
Thio relaxers have a pH above 10 because they contain alkaline substances that help to break down the disulfide bonds in the hair. This high pH level is necessary for the chemical reaction to occur and effectively relax the hair. Thio relaxers also use less ammonium thioglycolate (ATG) compared to perming solutions, as the goal is to relax the hair rather than create curls or waves. However, unlike perming solutions, thio relaxers do not use a reducing agent, which is responsible for reforming the disulfide bonds in permed hair.Rate this question:

Each step in the ph scale represents a - change in concentration.
- A.
Twofold
- B.
Twentyfold
- C.
Hundredfold
- D.
Tenfold
Correct Answer
D. TenfoldExplanation
Each step in the pH scale represents a tenfold change in concentration. This means that the concentration of hydrogen ions (H+) or hydroxide ions (OH-) in a solution increases or decreases by a factor of 10 as you move from one pH value to the next. For example, a solution with a pH of 3 is ten times more acidic than a solution with a pH of 4, and a solution with a pH of 9 is ten times more basic than a solution with a pH of 8.Rate this question:

Hydroxide relaxers remove one aton of sulfur from a disulfide bond and convert it into a lanthionin bond in a process called:
- A.
Reduction
- B.
Neuralization
- C.
Lanthionization
- D.
Oxidation
Correct Answer
C. LanthionizationExplanation
Hydroxide relaxers, such as sodium hydroxide or calcium hydroxide, are commonly used in hair treatments to straighten curly or frizzy hair. These relaxers work by breaking the disulfide bonds in the hair, which are responsible for its natural shape and texture. In this process, one atom of sulfur is removed from the disulfide bond and converted into a lanthionine bond. This conversion is known as lanthionization. Therefore, the correct answer is lanthionization.Rate this question:
-
- 7.
The disulfide bonds that are broken by hydroxide relaxers:
- A.
Can never be re-formed
- B.
Are re-formed by lanthionization
- C.
Are changed into hydrogen bonds
- D.
Are re-formed by neutralizer
Correct Answer
A. Can never be re-formedExplanation
The disulfide bonds that are broken by hydroxide relaxers can never be re-formed. This is because hydroxide relaxers permanently break the disulfide bonds in the hair, which are responsible for its natural curl or wave pattern. Once these bonds are broken, they cannot be repaired or re-formed. This is why hydroxide relaxers provide long-lasting straightening effects.Rate this question:

The neutralization of hydroxide relaxers involves the use of:
- A.
Oxidizing neutralizer
- B.
Acid-balanced shampoo
- C.
High -ph shampoo
- D.
Hydrogen peroxide
Correct Answer
B. Acid-balanced shampooExplanation
The neutralization of hydroxide relaxers involves the use of an acid-balanced shampoo. This is because hydroxide relaxers are highly alkaline and can cause damage to the hair if not properly neutralized. Acid-balanced shampoos help to restore the pH balance of the hair and scalp, bringing them back to a more neutral level. This helps to close the cuticle of the hair and prevent further damage. Oxidizing neutralizers are typically used with oxidative hair dyes, not relaxers. High-pH shampoos and hydrogen peroxide are not suitable for neutralizing hydroxide relaxers.Rate this question:

If you have treated a client's hair with a hydroxide relaxer, it cannot be treated with:
- A.
Future hydroxide relaxers
- B.
Thermal waving
- C.
Soft curl permanents
- D.
Permanent haircolor
Correct Answer
C. Soft curl permanentsExplanation
If a client's hair has been treated with a hydroxide relaxer, it cannot be treated with soft curl permanents. This is because hydroxide relaxers break down the protein bonds in the hair, permanently straightening it. Soft curl permanents, on the other hand, work by restructuring the protein bonds in the hair to create curls or waves. Since the protein bonds have already been broken down by the hydroxide relaxer, the soft curl permanents would not be effective in creating curls and waves in the hair.Rate this question:

Metal hydroxide relaxers are ionic compounds formed by a metal combined with
- A.
Oxygen and nitrogen
- B.
Nitrogen and hydrogen
- C.
Hydrogen and sulfer
- D.
Oxygen and hydrogen
Correct Answer
D. Oxygen and hydrogenExplanation
Metal hydroxide relaxers are ionic compounds formed by a metal combined with oxygen and hydrogen. This is because hydroxide ions (OH-) are formed when a metal combines with water, and the hydroxide ions combine with hydrogen ions (H+) to form water molecules (H2O). Therefore, the correct answer is oxygen and hydrogen.Rate this question:

Sodium hydroxide relaxers are commonly called:
- A.
No-lye relaxers
- B.
Lye relaxers
- C.
No-mix no-lye relaxers
- D.
Low-ph relaxers
Correct Answer
B. Lye relaxersExplanation
Sodium hydroxide relaxers are commonly called lye relaxers because they contain sodium hydroxide as the main active ingredient. Lye relaxers are known for their strong alkaline properties, which help break down the protein bonds in the hair, allowing it to be straightened. These relaxers have been used for many years and are known for their effectiveness in permanently straightening hair.Rate this question:

A chemical relaxer that straightens the hair completely but with much less scalp irritation than other hydroxide relaxers is:
- A.
Guanidine hydroxide relaxer
- B.
Sodium hydroxide relaxer
- C.
Lithium hydroxide relaxer
- D.
Low-ph relaxer
Correct Answer
A. Guanidine hydroxide relaxerExplanation
Guanidine hydroxide relaxer is the correct answer because it straightens the hair completely with less scalp irritation compared to other hydroxide relaxers. This suggests that guanidine hydroxide relaxer is a milder and less harsh option for straightening the hair, making it a preferable choice for individuals with sensitive scalps or those who experience irritation from other relaxers such as sodium hydroxide or lithium hydroxide relaxers. Additionally, the term "low-ph relaxer" does not specify a specific type of relaxer and does not provide information about its effectiveness or scalp irritation.Rate this question:

Chemical relaxers marketed as mild alternative relaxers are:
- A.
Guanidine hydroxide relaxer
- B.
Sodium hydroxide relaxer
- C.
Lithium hydroxide relaxer
- D.
Sulfites
Correct Answer
D. SulfitesExplanation
Chemical relaxers are used to straighten curly or kinky hair. Guanidine hydroxide, sodium hydroxide, and lithium hydroxide are all strong chemical relaxers that can permanently alter the hair's structure. Sulfites, on the other hand, are not typically used as relaxers but are sometimes marketed as mild alternatives. They are often used as preservatives or to reduce the harshness of other chemicals. Therefore, sulfites are the correct answer as they are the only option that fits the description of being marketed as a mild alternative relaxer.Rate this question:

Mild strength relaxers are recommended for fine, damaged, or:
- A.
Medium-curly hair
- B.
Medium-texture hair
- C.
Color-treated hair
- D.
Coarse, extremely curly hair
Correct Answer
C. Color-treated hairExplanation
Mild strength relaxers are recommended for color-treated hair because color-treated hair is often more fragile and prone to damage. Using a mild strength relaxer helps to minimize the risk of further damage and breakage, while still providing some relaxation to the hair. Stronger relaxers may be too harsh and can cause the color-treated hair to become even more damaged and weak.Rate this question:

The application for a vigin relaxer begins:
- A.
1/4" to 1/2" away from the scalp
- B.
Along the entire strand
- C.
At the scalp
- D.
At the new growth
Correct Answer
A. 1/4" to 1/2" away from the scalpExplanation
The correct answer is 1/4" to 1/2" away from the scalp. This is because applying the relaxer directly at the scalp can cause irritation and damage to the sensitive skin. By starting 1/4" to 1/2" away from the scalp, the relaxer can be evenly distributed along the entire strand, ensuring that the hair is relaxed uniformly without causing harm to the scalp.Rate this question:

Relaxer should be applied to the most resistant area first, which is uaually the:
- A.
Front hairline
- B.
Temples
- C.
Back of the head
- D.
Nape
Correct Answer
C. Back of the headExplanation
The back of the head is usually the most resistant area when it comes to applying a relaxer. This is because the hair in this area tends to be coarser and more tightly curled, making it harder for the relaxer to penetrate and straighten the hair. By applying the relaxer to the most resistant area first, it allows more time for the product to work on this area before moving on to the less resistant areas, ensuring that all of the hair is properly relaxed.Rate this question:

Normalizing solutions are conditioners with an acidic pH that are used in a relaxing procedure:
- A.
Prior to shampooing
- B.
Before applying relaxer
- C.
After shampooing
- D.
Before rinsing out relaxer
Correct Answer
A. Prior to shampooingExplanation
Normalizing solutions are used in a relaxing procedure to prepare the hair for the subsequent steps. By applying the solution prior to shampooing, it helps to remove any residue or buildup on the hair and scalp. This step ensures that the hair is clean and ready for the relaxer application. Normalizing solutions typically have an acidic pH, which helps to restore the hair's natural pH balance after the relaxer process. Therefore, applying the solution before shampooing is the correct step in the relaxing procedure.Rate this question:

To determine if the hair is sufficiently relaxed, do:
- A.
A patch test
- B.
Periodic strand testing
- C.
A test curl
- D.
A porosity test
Correct Answer
B. Periodic strand testingExplanation
Periodic strand testing is the most suitable method to determine if the hair is sufficiently relaxed. This test involves taking a small section of hair and applying the relaxer to see how it reacts. By observing the results, such as the texture and level of relaxation achieved, one can assess if the hair has been relaxed to the desired extent. This method allows for a more accurate evaluation of the hair's relaxation level compared to other options like a patch test, test curl, or porosity test, which may not provide sufficient information in this context.Rate this question:

To neutralize hydroxide relaxer, shampoo the hair with an acid-blanced shampoo at least:
- A.
Three times
- B.
Once
- C.
Twice
- D.
Five times
Correct Answer
A. Three timesExplanation
To neutralize hydroxide relaxer, the hair needs to be shampooed with an acid-balanced shampoo. Shampooing the hair three times ensures that all traces of the hydroxide relaxer are completely removed and the pH level of the hair is balanced. Shampooing only once or twice may not be sufficient to fully neutralize the relaxer, while shampooing five times may be excessive and could potentially strip the hair of its natural oils. Therefore, shampooing the hair three times is the recommended number of times to neutralize the hydroxide relaxer effectively.Rate this question:

A Jheri curl or soft curl permanent is a combination os a thio relaxer and:
- A.
Thermal waving
- B.
A hydroxide permanent
- C.
A hydroxide relaxer
- D.
A thio permanent
Correct Answer
D. A thio permanentExplanation
A Jheri curl or soft curl permanent is a hairstyle that involves the use of a thio relaxer, which is a type of chemical that breaks down the protein structure of the hair to make it more malleable. In addition to the thio relaxer, a Jheri curl also requires thermal waving, which involves using heat to set the hair in curls. Therefore, the correct answer is a thio permanent, as it is the combination of a thio relaxer and thermal waving that is used to achieve the Jheri curl or soft curl hairstyle.Rate this question:

In a soft curl permanent, the hair is first relaxed, then wrapped:
- A.
On horizontal base sections
- B.
On base
- C.
Off base
- D.
On vertical base sections
Correct Answer
A. On horizontal base sectionsExplanation
In a soft curl permanent, the hair is first relaxed to make it more pliable and easier to work with. Then, it is wrapped on horizontal base sections. This technique helps to create soft and natural-looking curls that flow horizontally along the head. By wrapping the hair on horizontal base sections, the curls will have a consistent shape and direction, resulting in a more uniform and balanced look.Rate this question:

When applying a hydroxide relaxer:
- A.
The client's hair must be damp
- B.
Gloves are not necessary
- C.
Begin at the scalp and hair ends
- D.
Do not shampoo first
Correct Answer
D. Do not shampoo firstExplanation
When applying a hydroxide relaxer, it is important not to shampoo the hair first. Shampooing the hair can remove the natural oils and moisture from the hair, making it more susceptible to damage from the relaxer. Instead, the hair should be dry and unwashed before applying the relaxer. This allows the natural oils to act as a protective barrier and minimize the risk of damage during the relaxing process.Rate this question:

You should not attempt to remove more than _ of the natural curl with chemical relaxing.
- A.
50%
- B.
80%
- C.
30%
- D.
70%
Correct Answer
B. 80%Explanation
Chemical relaxing is a process that is used to straighten curly or wavy hair. It involves the use of chemicals to break the protein bonds in the hair, allowing it to be reshaped. However, removing too much of the natural curl can lead to damage and breakage. Therefore, it is recommended to not remove more than 80% of the natural curl with chemical relaxing to maintain the health and integrity of the hair.Rate this question:
