A client with natural level 4 (medium brown) hair desires to achieve a level 8 (light blonde) result. This transformation will likely require a two-step process. What is the first crucial step in this type of major lightening service?

  1. APre-lighten the hair using a bleach or decolorizer.
  2. BApply a toner to neutralize unwanted underlying pigments.
  3. CApply a permanent hair color with a high-volume developer.
  4. DPerform a strand test to determine processing time.
Show answer & 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.
