California Cosmetology Written ExamHaircoloringMedium
A cosmetologist wants to use a high-lift blonde permanent color formula to lift a client's level 6 natural hair up to 4 levels lighter in a single application. Which developer volume is typically required for high-lift blonde formulas to achieve this maximum lift?
- A30 volume
- B10 volume
- C20 volume
- D40 volume
Show answer & explanationAnswer & explanation
Correct answer: D. 40 volume
High-lift blonde formulas are specifically designed to achieve maximum lift (typically up to 4 levels) and require 40 volume developer to generate sufficient oxygen release for that degree of lightening.
Why the other options are wrong
- A. 30 volume lifts about 2-3 levels, still short of maximum high-lift results.
- B. 10 volume only deposits color with minimal to no lift.
- C. 20 volume typically lifts about 1-2 levels, insufficient for high-lift results.
High-Lift Blonde Developer
High-lift blonde permanent color formulas require 40 volume developer to achieve their maximum lightening capability (up to 4 levels).
- High-lift lines are designed for maximum lift with minimal deposit
- 40 volume is the standard developer strength used
- Requires healthy hair to avoid excessive damage
Memory trick: '40 for the max'—high-lift blondes need the strongest developer.
