Milady Cosmetology Haircoloring and Lightening Questions and Answers — Questions and Answers
Question 1: A client with natural level 5 hair wants to achieve a level 9 blonde. This process will require lightening the hair first and then applying a separate color to tone it. Which of the following services is being performed?
- A single-process color
- A double-process color (Correct answer)
- A semi-permanent color
- A glaze application
Correct answer: A double-process color
A double-process color is a two-step service. The first step is to pre-lighten the hair, and the second step is to apply a toner or color to achieve the desired shade. This method is necessary when a client wants to go significantly lighter, such as from a level 5 to a level 9.
Question 2: When mixing a primary color with a neighboring secondary color on the color wheel, what type of color is created?
- A complementary color
- An intense color
- A tertiary color (Correct answer)
- A primary color
Correct answer: A tertiary color
Tertiary colors are created by mixing a primary color with its adjacent secondary color. Examples include blue-violet, red-orange, and yellow-green. This is a fundamental concept in the Law of Color used for formulation.
Question 3: Which type of hair lightener is generally used for off-scalp applications like foiling or balayage and comes in a thicker consistency that expands less?
- Oil lightener
- Cream lightener
- Powder lightener
- Clay lightener (Correct answer)
Correct answer: Clay lightener
Clay lighteners are specifically designed for off-scalp, freehand painting techniques like balayage. Their thicker consistency creates a shell-like barrier that keeps the product moist on the inside while preventing it from swelling and bleeding onto other sections of hair.
Question 4: A client's hair is determined to have low porosity. How will this characteristic likely affect the hair coloring process?
- The hair will absorb color very quickly and fade fast.
- The color will process faster and appear lighter than desired.
- The hair will be resistant to color penetration, possibly requiring longer processing time. (Correct answer)
- The hair will accept color evenly but will not hold cool tones.
Correct answer: The hair will be resistant to color penetration, possibly requiring longer processing time.
Low porosity hair has a tightly packed cuticle layer, which resists moisture and chemical penetration. This makes it more difficult for hair color to be absorbed, which can lead to uneven results or require a longer processing time to ensure proper coverage.
Question 5: What is the primary function of hydrogen peroxide (developer) when mixed with an oxidative hair color, such as permanent color?
- To condition the hair shaft during the coloring process.
- To act as a catalyst, activating the color molecules and helping them penetrate the cortex. (Correct answer)
- To coat the outside of the hair cuticle with color molecules for a temporary effect.
- To lower the pH of the hair color formula to prevent scalp irritation.
Correct answer: To act as a catalyst, activating the color molecules and helping them penetrate the cortex.
Hydrogen peroxide, the active ingredient in developer, acts as an oxidizing agent and catalyst. When mixed with permanent hair color, it opens the hair cuticle, allowing the uncolored dye precursors to penetrate into the cortex where they react, oxidize, and form large, permanent color molecules.
Question 6: Which category of haircolor is non-oxidative, does not require a developer, and has large color molecules that only coat the outside of the cuticle, resulting in color that lasts for only a few shampoos?
- Permanent haircolor
- Demi-permanent haircolor
- Temporary haircolor (Correct answer)
- High-lift tint
Correct answer: Temporary haircolor
Temporary haircolor is non-oxidative, meaning it does not use a developer. Its color molecules are large and cannot penetrate the cuticle layer, so they only sit on the outside of the hair shaft. This results in a physical, not chemical, change that is easily removed with shampooing.
