Question 1

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

Accepted Answer

Orange

Answer

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

Question 2

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

Accepted Answer

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

Answer

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.

Question 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?

Accepted Answer

It does not affect the result when going darker

Answer

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

Question 4

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

Accepted Answer

1:2

Answer

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

Question 5

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

Accepted Answer

Answer

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