A client presents with extremely porous hair that tends to absorb color very quickly and unevenly. To ensure a more even color application and prevent over-darkening, what pre-treatment strategy should the cosmetologist consider?

  1. AUse a darker shade of color.
  2. BApply a protein filler.
  3. CIncrease the developer volume.
  4. DPre-lighten the hair.
Show answer & explanation

Correct answer: B. Apply a protein filler.

Extremely porous hair has an open cuticle layer, leading to uneven color absorption. Applying a protein filler before coloring helps to equalize the porosity, filling in gaps in the cuticle and allowing for a more even and consistent color deposit.

Why the other options are wrong

  • A. Using a darker shade might mask unevenness but won't correct the underlying porosity issue, and could still lead to patchy results.
  • C. Increasing developer volume would cause more lift or increased lightening, exacerbating the unevenness on porous hair.
  • D. Pre-lightening would further open the cuticle and increase porosity, making the problem worse.

Protein Filler

A conditioning product containing proteins that is applied to porous hair before a color service to equalize porosity and ensure more even color absorption and retention.

  • Helps porous hair absorb color evenly.
  • Fills in gaps in the hair's cuticle layer.
  • Improves color longevity and vibrancy.
  • Often used before tinting or toning extremely porous hair.

Memory trick: Fill the Pores, Even the Cores
