When applying permanent haircolor to a client with resistant gray hair, which technique is recommended?
Answer: Pre-soften with 10-volume developer, then apply color
Pre-softening resistant gray hair with a mild developer opens the cuticle slightly, allowing the permanent color to penetrate and cover gray more effectively.
Which of the following best describes 'ombre' haircoloring?
Answer: A gradual color transition from darker roots to lighter ends
Ombre creates a seamless gradient effect, traditionally with darker color at the roots transitioning to a lighter shade toward the ends.
If a patch test (allergy test) shows redness and swelling 24–48 hours after application, the cosmetologist should:
Answer: Refuse to perform the service and refer client to a physician
A positive patch test indicating allergy means the client could have a severe anaphylactic reaction; the service must be refused and the client referred to a doctor.
Which color theory principle explains why a purple toner neutralizes yellow tones in blonde hair?
Answer: Complementary colors directly opposite on the color wheel cancel each other
Purple and yellow are complementary colors (directly opposite on the color wheel), so purple pigment neutralizes yellow brassiness in blonde hair.
What is the main advantage of balayage over traditional foil highlights?
Answer: Balayage creates a softer, more natural-looking grow-out with less maintenance
Balayage's freehand painting technique produces softer, blended results with a gradual grow-out, reducing the frequency of touch-up appointments.
Which ingredient in permanent haircolor is responsible for opening the cuticle to allow dye penetration?
Answer: Ammonia
Ammonia is an alkaline agent that raises the pH and swells the cuticle open, allowing the dye intermediates to enter the cortex.
A client's hair turned orange after a single-process lightening attempt. This indicates the hair has lifted to approximately which level?
Answer: Level 6–7
Orange contributing pigment is exposed at approximately levels 6–7, indicating the hair has reached that mid-range lift stage and still contains significant warm red-orange melanin.
