,1. A client presents with uneven hair color after using a high-lift
blonde kit. The hair shows warm brassy tones and patchy lightening.
What is the most likely cause?
A) Using a developer with too low volume
B) Inadequate pre-lightening and poor product mixing
C) Too short processing time
D) Hair was overly porous before application
ANS: B
Rationale: Uneven lightening and warm brassiness typically result
from inadequate or uneven pre-lightening and improper mixing of the
product, leading to inconsistent lift and unwanted warm tones.
2. When performing a color correction on hair with previously applied
semi-permanent color, what is the best approach to remove the
semi-permanent pigment?
A) Use a bleach bath (color removal with low volume peroxide)
B) Apply a higher volume developer directly
C) Use a color remover specifically designed for direct dyes
D) Use permanent hair color formulation
ANS: C
Rationale: Semi-permanent colors are usually direct dyes and cannot
be removed effectively with peroxide; a specifically formulated color
remover works by breaking down the dye molecules without
damaging the hair.
3. You are tasked with neutralizing green tones on pre-lightened
blonde hair. Which toner would you select?
A) Red-based toner
B) Magenta or red-violet-based toner
C) Yellow-based toner
D) Blue-based toner
2
,ANS: B
Rationale: Green tones are neutralized by red or red-violet pigments,
which are complementary colors to green, effectively canceling it out.
4. Why is it important to consider the hair’s porosity before selecting a
color formulation?
A) To predict the hair’s ability to absorb and hold dye molecules
B) To determine the correct shampoo to recommend afterward
C) To decide the hair’s cuticle pattern
D) To choose the right haircut style
ANS: A
Rationale: Hair porosity affects how well hair absorbs and retains
color; overly porous hair may absorb color too quickly or unevenly,
necessitating formula adjustments.
5. What is the primary difference between oxidative and direct dyes in
hair coloring?
A) Oxidative dyes require a developer, direct dyes do not
B) Direct dyes only lighten hair
C) Direct dyes last longer than oxidative dyes
D) Oxidative dyes are used only for semi-permanent hair color
ANS: A
Rationale: Oxidative dyes require developers to activate and
penetrate the cortex, resulting in longer-lasting color; direct dyes
deposit color on the hair surface without developer.
6. A client’s hair has been over-processed with bleach leading to
severe elasticity loss. What remedial action should be taken before
attempting further color correction?
A) Immediate application of permanent color
B) Protein treatments and moisture rebuilding services
C) Repeated bleaching to balance hair texture
3
, D) Use a stronger developer to seal the hair
ANS: B
Rationale: Severely damaged hair needs rebuilding through protein
and moisture treatments to restore elasticity before safely applying
further chemicals.
7. You want to formulate a color to achieve a cool beige blonde on
level 8 hair. Which base tone and tone modifier would you choose?
A) Yellow base with gold tones
B) Neutral base with ash (blue-green) tones
C) Red base with copper tones
D) Warm base with orange tones
ANS: B
Rationale: Ash tones (blue-green) cool down warm yellow bases,
helping achieve a cool beige blonde.
8. What is the effect of increasing developer volume from 10 to 30 on
hair color lightening?
A) Decreases lift, intensifies tone
B) Increases lift by opening cuticle and activating more pigment
removal
C) Changes hair porosity
D) Has no effect on lift
ANS: B
Rationale: Higher volume developers produce more peroxide, lifting
more pigment by opening the cuticle more aggressively.
9. How does the Law of Color help in formulating a color to
counteract unwanted tones?
A) It describes hair damage patterns
B) It identifies the direct action of pigment on hair texture
C) It establishes complementary color relationships for neutralizing
