California Barber Written ExamHair Care ServicesHard

A barber is performing a hair coloring service and observes that the client's hair has uneven porosity, with the ends being significantly more porous than the roots. What is the most appropriate strategy to ensure an even color result from roots to ends?

  1. AApply color to the most porous areas first, then the less porous areas.
  2. BPre-condition the porous ends with a protein filler before applying color.
  3. CUse a higher volume developer on the porous ends and a lower volume on the roots.
  4. DApply the color to the roots first, then immediately apply to the ends.
Show answer & explanation

Correct answer: B. Pre-condition the porous ends with a protein filler before applying color.

Uneven porosity means different parts of the hair absorb color differently. Pre-conditioning the highly porous ends with a protein filler helps to even out the hair's porosity by temporarily filling in the gaps in the cuticle. This allows the color to be absorbed more uniformly, preventing overly dark or dull ends and ensuring an even color result from roots to ends.

Why the other options are wrong

  • A. Applying color to porous areas first would likely result in those areas absorbing too much color and becoming darker or duller than the rest.
  • C. Developer volume controls lift, not porosity. Using a higher volume on ends could cause over-processing and damage without addressing porosity.
  • D. Applying to roots first and then immediately to ends would still result in the porous ends grabbing too much color due to their higher absorption rate.

Porosity Equalization

Porosity equalization, typically achieved with protein fillers or porosity equalizers, is a hair coloring technique used to ensure even color absorption on hair with varying porosity levels, preventing uneven color results.

  • Addresses uneven color absorption.
  • Protein fillers temporarily fill cuticle gaps.
  • Creates a more uniform canvas for color.
  • Prevents over-darkening or dullness in porous areas.

Memory trick: Fill the 'pores' for 'perfect' color scores.
