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?
- ASemi-permanent hair color
- BPermanent hair color
- CDemi-permanent hair color
- DTemporary hair color
Show answer & explanationAnswer & 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.
