Cosmetology Test Haircolor and Lightening 2 — Questions and Answers
Question 1: What is the term for the process of removing artificial haircolor from the hair shaft?
- Color correction
- Color extraction
- Color stripping (Correct answer)
- Color lifting
Correct answer: Color stripping
Color stripping (also called color removal) uses reducing agents to break down artificial pigment molecules so they can be rinsed from the hair.
Question 2: Which haircolor level system ranges from 1 (darkest) to 10 (lightest)?
- Tone system
- Depth system (Correct answer)
- Lift system
- Saturation system
Correct answer: Depth system
The depth system (also called level system) classifies hair from level 1 black to level 10 lightest blonde.
Question 3: A client wants to go from level 4 brown to level 9 blonde in one service. What is the most appropriate approach?
- Apply a high-lift tint with 40-volume developer
- Apply bleach only and tone after (Correct answer)
- Apply a single-process color with 20-volume developer
- Use a demi-permanent color with 10-volume developer
Correct answer: Apply bleach only and tone after
Going from level 4 to level 9 typically requires bleach to lift 5 levels, followed by a toner to achieve the desired blonde shade.
Question 4: What causes haircolor to fade faster when exposed to sunlight?
- Oxidation from UV rays breaks down color molecules (Correct answer)
- Melanin reactivates and pushes out artificial pigment
- Sunlight causes the cuticle to permanently close
- Heat from the sun rebuilds disulfide bonds
Correct answer: Oxidation from UV rays breaks down color molecules
UV radiation from sunlight oxidizes and degrades artificial color molecules, causing the color to fade or shift tone.
Question 5: When performing a highlighting service, foils are placed to avoid touching the scalp primarily to:
- Prevent the client from feeling heat
- Avoid scalp irritation and achieve a grow-out effect (Correct answer)
- Prevent bleeding between foil sections
- Allow the color to process at a cooler temperature
Correct answer: Avoid scalp irritation and achieve a grow-out effect
Leaving a small gap from the scalp avoids skin irritation and creates a natural-looking grow-out, which is a hallmark of foil highlights.
Question 6: What is the primary difference between a tint and a toner in haircoloring?
- Tints only deposit color while toners only lift color
- Tints contain ammonia and lift while toners deposit tone without significant lift (Correct answer)
- Toners contain higher developer volumes than tints
- Tints are permanent while toners are always temporary
Correct answer: Tints contain ammonia and lift while toners deposit tone without significant lift
Tints contain ammonia and oxidative dye to lift and deposit, while toners are low-ammonia or ammonia-free formulas applied after lightening to refine the tone.
Question 7: Which of the following best describes 'on-the-scalp' bleach?
- A bleach formula safe for direct scalp application (Correct answer)
- Any bleach applied without foils
- A bleach used exclusively for highlights
- A bleach mixed with a high-volume developer for off-scalp use only
Correct answer: A bleach formula safe for direct scalp application
On-the-scalp bleach formulas are specifically designed to be gentler so they can be applied directly to the scalp without causing excessive irritation.
