- APre-lighten the hair using a bleach or decolorizer.
- BApply a toner to neutralize unwanted underlying pigments.
- CApply a permanent hair color with a high-volume developer.
- DPerform a strand test to determine processing time.
Show answer & explanationAnswer & explanation
Correct answer: A. Pre-lighten the hair using a bleach or decolorizer.
To lighten natural hair four levels (from 4 to 8), pre-lightening (bleaching or decolorizing) is the essential first step. Permanent hair color can only lift 3-4 levels on its own, and attempting to achieve a light blonde from a medium brown in one step with color alone often results in unwanted warm tones or insufficient lift. Toning comes after pre-lightening.
Why the other options are wrong
- B. Toner is applied after the desired lightening level is achieved to neutralize undertones, not as the first step.
- C. A single application of permanent hair color with high-volume developer might not achieve enough lift (4 levels) and could leave unwanted warm tones.
- D. While a strand test is crucial throughout the process, it is not the 'first crucial step' of the chemical service itself; pre-lightening is the first application.
Double-Process Blonding
Double-process blonding involves two main steps: first, pre-lightening the hair with bleach to achieve the desired lightness, and second, applying a toner or permanent color to achieve the final desired shade and neutralize unwanted undertones.
- Required for significant lightening (4+ levels).
- First step: pre-lighten with bleach.
- Second step: tone or color to desired shade.
- Crucial for achieving clean, light blonde results.
Memory trick: Lighten first, then perfect the blonde.
