NIC Barber Written (Theory) ExamHair Care ServicesHard

A barber is performing a consultation for a client who desires to achieve a lighter shade of blonde from their current light brown hair. The client has some existing highlights. During the hair analysis, the barber notes that the hair has uneven porosity, with the highlighted areas being more porous. Which product application technique should the barber consider to ensure even lifting and minimize damage?

  1. AApply the lightener uniformly from scalp to ends simultaneously.
  2. BApply the lightener to the ends first, then mid-shaft, then scalp.
  3. CApply the lightener to the darker, less porous areas first, then to the lighter, more porous areas.
  4. DApply a protein treatment before lightener application and then apply uniformly.
Show answer & explanation

Correct answer: C. Apply the lightener to the darker, less porous areas first, then to the lighter, more porous areas.

Applying lightener to the darker, less porous areas first allows these sections more processing time to lift. The more porous, previously highlighted areas, which lift faster, should receive the lightener last to prevent over-processing and damage.

Why the other options are wrong

  • A. Uniform application would lead to over-processing and damage on the more porous highlighted areas before the darker areas have adequately lifted.
  • B. Applying to ends first is typically for virgin hair darker than mid-shaft/scalp, not for uneven porosity where highlights exist.
  • D. While a protein treatment can help, it does not address the need for a differential application strategy for uneven porosity.

Porosity-Controlled Lightener Application

A hair lightening technique where the product is applied strategically to different sections of the hair based on their porosity levels. Less porous (darker, virgin) areas receive the lightener first, allowing more processing time, while more porous (lighter, previously treated) areas are addressed later to prevent over-processing.

  • Essential for achieving even lift on hair with uneven porosity.
  • Protects previously lightened or damaged areas from further harm.
  • Requires careful assessment of hair's condition and history.

Memory trick: Dark first, then light to balance the lift.
