NIC Barber Written (Theory) ExamHair Care ServicesEasy

A barber is performing a consultation for a client who desires to achieve a lighter shade than their natural hair color. The client also wants the color to be long-lasting and provide complete gray coverage. Which type of hair color product would be most appropriate?

  1. ASemi-permanent hair color
  2. BPermanent hair color
  3. CDemi-permanent hair color
  4. DTemporary hair color
Show answer & explanation

Correct answer: B. Permanent hair color

Permanent hair color is the only type capable of both lightening natural hair color and providing long-lasting, complete gray coverage, as it uses an oxidative dye and developer to penetrate the cortex and alter the hair's natural pigment.

Why the other options are wrong

  • A. Semi-permanent hair color deposits color but cannot lighten natural hair.
  • C. Demi-permanent hair color can deposit color but cannot lighten natural hair.
  • D. Temporary hair color only coats the surface and cannot lighten hair.

Permanent Hair Color (Lightening)

Hair color products formulated with an oxidative dye and a developer (hydrogen peroxide) that lift the natural hair pigment and deposit new color simultaneously, resulting in a long-lasting color change, including lightening.

  • Uses developer to lighten natural pigment
  • Deposits new color
  • Provides long-lasting results
  • Offers complete gray coverage
  • Requires a patch test

Memory trick: To lighten and last, permanent color is a must.
