  1. What underlying pigment is typically exposed when hair at a natural level 4 (medium brown) is lightened to level 6?

    Answer: Orange

    Level 4 hair reveals orange underlying pigment when lifted to approximately level 6 during the lightening process.

  2. Which statement best describes the difference between semi-permanent and demi-permanent hair color?

    Answer: Demi-permanent uses a low-volume developer; semi-permanent typically does not use peroxide

    Demi-permanent color uses a low-volume (5–10) developer to partially penetrate the cortex, while semi-permanent deposits color without peroxide and fades gradually.

  3. A colorist wants to darken a client's hair by two levels using a permanent formula. What should she consider about the natural underlying pigment?

    Answer: It does not affect the result when going darker

    When applying permanent color darker, the underlying pigment is covered and does not significantly affect the final result.

  4. Which mixing ratio is standard for most powder lighteners used with 20 volume developer?

    Answer: 1:2

    Most powder lighteners are mixed at a 1:2 ratio (one part lightener to two parts developer) for proper consistency.

  5. What is 'foiling' designed to accomplish in a highlight service?

    Answer: Isolate color-treated sections from untreated hair

    Foiling isolates highlighted sections from the rest of the hair, preventing unwanted color bleeding and allowing precise placement.

  6. A client's hair has been colored dark brown (level 3) for years. She now wants platinum blonde. What must the stylist explain?

    Answer: Multiple lightening sessions are likely needed to avoid severe damage

    Going from dark permanent color to platinum typically requires multiple controlled lightening sessions to avoid severe breakage and maintain hair integrity.

  7. Which term describes a color formula that contains no ammonia and deposits tone without lightening the natural base?

    Answer: Deposit-only color

    Deposit-only color formulas contain no ammonia and only add tone and depth without lifting the natural hair color.
