A client with naturally dark brown hair (level 3) desires to achieve a vibrant, light blonde result (level 9 or 10). What is the most effective and commonly used two-step hair coloring process to achieve this significant lift and tone?
- ADouble-process blonding (lightener then toner)
- BTemporary color followed by semi-permanent color
- CSingle-process blonding with high-lift tint
- DDemi-permanent color followed by permanent color
Show answer & explanationAnswer & explanation
Correct answer: A. Double-process blonding (lightener then toner)
Double-process blonding involves two distinct steps: first, applying a lightener (bleach) to lift the natural pigment to the desired level, and second, applying a toner to neutralize unwanted warm undertones and achieve the target blonde shade. This is essential for such a significant lift from dark brown to light blonde.
Why the other options are wrong
- B. Temporary and semi-permanent colors only coat the hair surface or stain the cuticle, offering no lift or significant color change, and certainly not a light blonde from dark brown.
- C. Single-process blonding with high-lift tint can achieve 4-5 levels of lift but is typically insufficient for lifting dark brown (level 3) directly to a very light blonde (level 9-10) without undesirable warm undertones.
- D. Demi-permanent and permanent colors are for depositing color, not for achieving such a significant lift from dark brown to light blonde; demi-permanent offers no lift.
Double-Process Blonding
A two-step hair coloring technique involving first using a lightener (bleach) to achieve the desired level of lift, then applying a toner to neutralize unwanted tones and create the final blonde shade.
- Used for significant lift (6+ levels).
- Lightener removes natural pigment.
- Toner refines the desired blonde tone.
Memory trick: DOUBLE-process for DOUBLE the lift and tone.
