Haircolor and Lightening Flashcards

What is the term for the process of removing artificial haircolor from the hair shaft?

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.

Which haircolor level system ranges from 1 (darkest) to 10 (lightest)?

Answer: Depth system

The depth system (also called level system) classifies hair from level 1 black to level 10 lightest blonde.

A client wants to go from level 4 brown to level 9 blonde in one service. What is the most appropriate approach?

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.

What causes haircolor to fade faster when exposed to sunlight?

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.

When performing a highlighting service, foils are placed to avoid touching the scalp primarily to:

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.

What is the primary difference between a tint and a toner in haircoloring?

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.

Which of the following best describes 'on-the-scalp' bleach?

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.
