Milady Cosmetology Haircoloring and Lightening 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?

Accepted Answer

A double-process color

Answer

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?

Accepted Answer

A tertiary color

Answer

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?

Accepted Answer

Clay lightener

Answer

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?

Accepted Answer

The hair will be resistant to color penetration, possibly requiring longer processing time.

Answer

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?

Accepted Answer

To act as a catalyst, activating the color molecules and helping them penetrate the cortex.

Answer

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.
