California Cosmetology Written ExamHaircoloringMedium
A client with 30% gray wants to blend her gray hair with a natural-looking result but is concerned about damage and does not want any lift in her natural level. Which product category best meets this need?
- APermanent color mixed with 30 volume developer
- BTemporary color rinse
- CLightener mixed with a color filler
- DDemi-permanent color mixed with a low volume developer (usually 10 volume)
Show answer & explanationAnswer & explanation
Correct answer: D. Demi-permanent color mixed with a low volume developer (usually 10 volume)
Demi-permanent color is a deposit-only oxidative color typically mixed with a low volume developer (around 10 volume), which is enough to open the cuticle slightly for gray blending without lifting the natural pigment, minimizing damage compared to permanent color.
Why the other options are wrong
- A. 30 volume developer would lift the hair, which the client does not want
- B. Temporary color will not adequately blend gray for a lasting result
- C. Lightener with filler is used for color correction, not gray blending without lift
Demi-Permanent Color
An oxidative, deposit-only color mixed with low volume developer that blends gray without lifting natural level.
- Typically mixed with 10 volume developer
- Deposits color only, does not lighten
- Less damaging alternative to permanent color for gray blending
Memory trick: Demi = 'Demi-lift', deposits gently with low volume developer
