,Question 1. What does a cold wave do to the hair?
A client visits the salon requesting a permanent wave to create long-lasting curls.
Before beginning the service, the cosmetologist explains how the chemical
solution will affect the hair structure during the cold wave process. The client
wants to understand what happens to her hair before it is reshaped around the
perm rods. Based on cosmetology principles, what does a cold wave do to the
hair?
Correct Answer: It softens and expands the hair strand.
Rationale: A cold wave softens and expands the hair strand by breaking down
some of the disulfide bonds within the hair's cortex, allowing the hair to become
flexible enough to assume the shape of the perm rod. Once the desired shape is
achieved, the neutralizer rebuilds these bonds to lock the new curl pattern into
place. Understanding this chemical action is essential because proper processing
ensures predictable curl formation while minimizing unnecessary damage to the
hair shaft.
Question 2. Size of the rod will determine?
A client requests loose, beach-style waves rather than tight curls during a
permanent waving service. Before selecting the perm rods, the cosmetologist
carefully evaluates the client's desired outcome and explains that different rod
sizes produce different curl patterns. Which characteristic of the finished hairstyle
is determined by the size of the perm rod selected?
Correct Answer: The size of the curl.
Rationale: The size of the curl is directly determined by the diameter of the
perm rod used during the service. Larger rods create larger, looser curls or body
waves, while smaller rods produce tighter, more defined curls. Selecting the
appropriate rod size is essential for meeting the client's expectations and
achieving consistent results throughout the hairstyle.
Question 3. A client complained that her hair was straight after a permanent
wave. What is the cause of the problem?
,A client returns to the salon one day after receiving a permanent wave and
reports that her hair appears nearly as straight as it was before the service. Upon
reviewing the procedure, the cosmetologist confirms that the rods were wrapped
correctly and the neutralizer was applied appropriately. What is the most likely
cause of the unsatisfactory result?
Correct Answer: Underprocessing.
Rationale: Underprocessing occurs when the waving solution is not allowed
sufficient time to break enough disulfide bonds to permanently reshape the hair.
As a result, the hair cannot fully conform to the rod pattern, producing weak curls
or little to no curl at all. Monitoring processing time through strand testing and
following manufacturer recommendations helps ensure successful curl formation
while avoiding unnecessary damage.
Question 4. After a chemical relaxer, the cosmetologist noticed the hair went
back to its natural wave. Why is this?
A cosmetologist performs a chemical relaxer service on a client with tightly curled
hair. After rinsing, drying, and evaluating the results, the stylist notices that much
of the hair has reverted to its original curl pattern instead of remaining straight.
What is the most likely reason this occurred?
Correct Answer: Insufficient processing time.
Rationale: Insufficient processing time prevents the relaxer from adequately
breaking enough disulfide bonds to permanently straighten the hair. When the
chemical is removed too soon, the hair retains much of its original texture and
elasticity, causing it to revert to its natural curl pattern. Proper timing according to
the manufacturer's instructions and frequent strand evaluations help achieve
effective straightening while reducing the risk of overprocessing.
Question 5. How long does an alkaline perm process for?
A cosmetologist prepares to perform an alkaline permanent wave on a client with
healthy, resistant hair. Before beginning the procedure, the client asks how long
the chemical solution will remain on the hair during processing. According to
, standard cosmetology guidelines, what is the typical processing time for an
alkaline permanent wave?
Correct Answer: 5 to 20 minutes.
Rationale: An alkaline permanent wave generally processes for 5 to 20
minutes, depending on the client's hair texture, porosity, condition, and the
manufacturer's recommendations. Frequent strand checks should be performed
throughout the processing period to determine when the desired curl formation
has been achieved. Following the recommended timing helps ensure consistent
results while minimizing the risk of hair damage caused by overprocessing.
Question 6. A client comes in need of a touch-up on her roots. She has light
brown hair and her regrowth is dark brown. What is the application process?
A returning client schedules a root touch-up because her natural dark brown
regrowth is visible against her previously colored light brown hair. The previously
colored lengths remain even in tone and require no additional color correction.
During the service, how should the cosmetologist apply the hair color?
Correct Answer: Apply color to the new growth only.
Rationale: Color should be applied only to the new growth because this is the
portion requiring color correction. Reapplying permanent color to previously
processed hair can lead to uneven color, excessive pigment buildup, and
unnecessary chemical damage. Isolating the regrowth ensures uniform color
results while preserving the health and integrity of the previously colored hair.
Question 7. What should the first step be in a haircut?
A cosmetologist welcomes a client who requests a precision haircut with even
layering throughout the head. Before making the first cut, the stylist prepares the
hair to ensure organization, balance, and accuracy during the service. What
should be the first step in the haircutting process?
Correct Answer: Section the hair.
Rationale: Sectioning the hair establishes control and allows the cosmetologist
to work methodically throughout the haircut. Organized sections help maintain
