Question 1: Which relaxing solution is applied to extremely resistant hair?

A. Ammonium persulfate.

B. No-lye relaxer.

C. Ammonium thioglycolate.

D. Sodium hydroxide.

The correct answer is D. Sodium hydroxide. Here are four detailed reasons

1. Sodium hydroxide relaxers, also known as lye relaxers, are best suited for extremely resistant hair types due to their strong alkaline formula. This type of relaxer is capable of breaking down the strong protein bonds in resistant hair, resulting in a more effective straightening outcome.

2. The high pH level of sodium hydroxide relaxers allows for a more thorough and long-lasting straightening effect on resistant hair. This type of relaxer penetrates the hair shaft deeply, resulting in a significant reduction of curl or wave pattern in highly resistant hair textures.

3. Sodium hydroxide relaxers are known for their fast-acting properties, making them ideal for use on extremely resistant hair that requires more processing time and stronger chemical action to achieve desired results. The efficiency of sodium hydroxide relaxers can help to effectively relax even the most stubborn or coarse hair types.

4. It is important to note that sodium hydroxide relaxers are powerful chemical treatments that can cause damage if not applied correctly. Therefore, it is crucial to follow proper application techniques, timing, and post-treatment care to ensure the safety and health of the hair during and after the relaxing process on extremely resistant hair.

Question 2: When cutting hair with medium graduation, at which angle must the hair be held?

A. 0°

B. 45°

C. 90°

D. 135°

The correct answer is B. 45°. Here are four detailed reasons

1. When cutting hair with medium graduation, the hair should be held at a 45° angle to the head. This angle helps to create a balanced and layered effect in the haircut, with a gradual increase in length from the shorter to longer sections of hair.

2. Holding the hair at a 45° angle allows the stylist to control the amount of weight removal and layering in the haircut. This angle is ideal for achieving medium graduation, where the hair cascades down smoothly with a soft transition between lengths.

3. The 45° angle is often used in haircutting techniques to create movement and texture in the hair. By holding the hair at this angle, the stylist can achieve a natural and blended look that enhances the shape and silhouette of the haircut.

4. Maintaining a consistent 45° angle while cutting ensures that the graduation is even and well-balanced throughout the haircut. This angle helps to create a seamless flow of layers and adds dimension to the hair, resulting in a polished and stylish finish.

Question 3: What is the effect of a damp comb on thermally straightened hair?

A. No effect.

B. It increases volume.

C. It reverts to natural curls.

D. It controls static.

The correct answer is C. It reverts to natural curls. Here are four detailed reasons

1. When thermally straightened hair comes into contact with dampness, such as from a damp comb or humidity in the air, it can cause the hair to revert to its natural curls or wave pattern. The moisture disrupts the temporary alteration of the hair's structure achieved through thermal straightening, leading to the hair returning to its original texture.

2. The heat and styling process involved in thermal straightening temporarily alters the bonds within the hair shaft to create a straightened appearance. However, moisture can disrupt these altered bonds, causing the hair to revert to its natural state, which may include curls or waves.

3. Dampness can also affect the smoothness and sleekness of thermally straightened hair, as it can cause the hair shaft to swell and become frizzy or unruly. This can result in a loss of the straightened effect and a return to the hair's natural texture.

4. To maintain the straightened result of thermally straightened hair, it is important to avoid exposure to dampness or humidity. Using products that help to protect against moisture and maintaining a good hair care routine can help prolong the effects of thermal straightening and keep the hair looking sleek and straight.

Question 4: What hairspray is used when brushing out a hot roller set?

A. Wet hairspray.

B. A working hairspray.

C. Non-aerosol hairspray.

D. Firm hairspray.

The correct answer is B. A working hairspray. Here are four detailed reasons

1. A working hairspray is the most suitable option for brushing out a hot roller set because it provides a flexible hold and allows for manipulation of the hair without stiffness or stickiness. This type of hairspray offers a workable hold that can be restyled as needed during the brushing-out process.

2. Working hairsprays typically have a light to medium hold, making them ideal for setting styles like hot roller sets that require flexibility and movement. The hairspray helps to maintain the shape and volume of the curls while allowing the hair to be brushed out and styled without becoming stiff or crunchy.

3. Using a working hairspray during the brushing out of a hot roller set helps to control frizz, add shine, and enhance the overall finish of the hairstyle. The hairspray provides a light hold that keeps the curls in place while allowing for smooth brushing and styling.

4. Working hairsprays are designed to be brushed out easily, making them a suitable choice for hairstyles that require manipulation and shaping, such as hot roller sets. The hairspray can be used to set the style and then brushed out to achieve a soft, natural-looking finish while maintaining hold and control.

Question 5: When relaxing permanent waved hair, which product is applied?

A. Thioglycolate relaxant.

B. Stabilizing relaxant.

C. Sodium hydroxide relaxant.

D. Sodium bromate relaxant.

The correct answer is A. Thioglycolate relaxant. Here are four detailed reasons

1. When relaxing permanently waved hair, a thioglycolate relaxant is typically used. Thioglycolate-based relaxers work by breaking the disulfide bonds in the hair, allowing for the restructuring of the hair's protein bonds to create a straighter or smoother texture.

2. Thioglycolate relaxants are commonly used for relaxing hair that has been previously permed with a waving lotion containing thioglycolate. This type of relaxant is compatible with the chemical composition of the previously permed hair, ensuring a safe and effective relaxing process.

3. Thioglycolate relaxants are milder than sodium hydroxide relaxants, making them a preferred choice for relaxing hair that has been previously chemically treated. They work by softening and loosening the hair's natural curl pattern, resulting in a straighter and more manageable texture.

4. It is important to follow the manufacturer's instructions and recommended application techniques when using a thioglycolate relaxant to relax previously permed hair. Proper timing, sectioning, and rinsing procedures should be followed to ensure a successful relaxing process and minimize the risk of damage to the hair.

Question 6: What is done to avoid offshades when blending grey hair with semi-permanent colour?

A. Fill the hair first.

B. Condition the hair first.

C. Add warmth to the formula.

D. Add natural to the formula.

The correct answer is D. Add natural to the formula. Here are four detailed reasons

1. Adding natural tones to the formula helps to balance the color and prevent offshades when blending grey hair with semi-permanent color. Natural tones help to mimic the underlying pigments in the hair and create a more harmonious and flattering result.

2. Grey hair often lacks pigment, which can lead to unpredictable color results when applying semi-permanent color. By adding natural tones to the formula, the colorist can create a base that complements the existing hair color and helps to achieve a more natural-looking blend with the grey hair.

3. Adding natural tones can help to create depth and dimension in the hair color, especially when blending grey hair. Natural tones provide a subtle undertone that enhances the overall color result and prevents any unwanted offshades or tones from appearing in the final color.

4. Natural tones can help to soften the contrast between the grey hair and the semi-permanent color, creating a seamless and blended transition. By incorporating natural tones into the formula, the colorist can achieve a more cohesive and flattering color outcome that enhances the overall look of the hair.

Question 7: When colouring hair, which volume of peroxide is required to lift a natural level of 5 to 8?

A. 10

B. 20

C. 30

D. 40

The correct answer is C. 30. Here are four detailed reasons

1. When lifting natural hair levels of 5 to 8, a 30-volume peroxide is typically required to achieve the desired level of lift. The higher the volume of peroxide, the more lifting power it has to lighten the hair.

2. Using a 30-volume peroxide is suitable for lifting the natural pigment in hair that is within the range of levels 5 to 8. This strength of peroxide helps to lighten the hair to a desired level while also minimizing the risk of damage.

3. A 30-volume peroxide is a moderate-strength developer that provides sufficient lift without excessive damage to the hair. It is effective for lightening natural hair colors within the specified range while maintaining the hair's condition and integrity.

4. It is important to consider the starting level of the hair and the desired result when selecting the appropriate volume of peroxide for the color process. Using a 30-volume peroxide ensures controlled and effective lightening of natural hair levels 5 to 8, resulting in a successful and balanced color outcome.

Question 8: What results from overlapping when applying a lightener on previously lightened hair?

A. Breakage of the hair.

B. Under porous hair.

C. Brassiness.

D. A chemical blowout.

The correct answer is A. Breakage of the hair. Here are four detailed reasons

1. Overlapping a lightener on previously lightened hair can lead to breakage of the hair strands. Repeated exposure to the strong chemicals in the lightener can weaken the hair's structure, causing it to become brittle and prone to breakage.

2. When a lightener is applied to areas of the hair that have already been lightened, the overlapping sections can become overprocessed. This can result in the hair becoming more fragile and susceptible to damage, leading to breakage and potential hair loss.

3. Overlapping lighteners can also cause uneven lightening and patchy results on the hair. The overlapping sections may lift more quickly or to a lighter level than the rest of the hair, creating an uneven and discolored appearance that may require corrective color treatments.

4. To prevent breakage and damage from overlapping lighteners, it is important to carefully section the hair and apply the lightener only to the regrowth or new growth areas. Avoiding overlap and monitoring the processing time closely can help to achieve a uniform and healthy lightening result without compromising the hair's integrity.

Question 9: What is the first step to shape a wig?

A. Hold it in the hand.

B. Lay it flat.

C. Pin it to a block.

D. Place it on the client's head.

The correct answer is C. Pin it to a block. Here are four detailed reasons

1. Pinning the wig to a block is the first step in shaping a wig because it provides a stable and secure foundation for styling. The block mimics the shape and size of a human head, allowing the stylist to work on the wig in a controlled and realistic manner.

2. Pinning the wig to a block helps to maintain the shape and structure of the wig while styling. This allows the stylist to shape the wig, add volume, and create the desired hairstyle without causing damage to the wig or distorting its original form.

3. By pinning the wig to a block, the stylist can easily access all parts of the wig for styling. This ensures that the styling process is even and consistent throughout the wig, resulting in a cohesive and polished look.

4. Pinning the wig to a block also allows the stylist to adjust the fit and balance of the wig during the shaping process. This step ensures that the wig sits comfortably on the client's head and that the style is customized to suit the client's preferences and needs.
