Hair Coloring and Lightening — practice questions
19.5% of the exam ≈25 real questions 30 free questions here
The largest block on either exam — 39% of the clinical test, about 25 of its 65 questions. Levels and tones, the underlying pigment exposed at each stage of lift, neutralizing with the complement, developer volumes, the four categories of color product, and virgin application order. Almost everything here is reasoning, not recall: you are shown a starting level and a target and asked what actually gets you there.
Where people lose points
- Level is lightness or darkness. Tone is warmth or coolness. They are two independent axes and the exam separates them on purpose — a level 7 can be ash, neutral or gold, and changing tone is not the same job as changing level.
- Underlying pigment is exposed in a fixed order as you lift: red, red-orange, orange, yellow-orange, yellow, pale yellow. If you cannot recite that sequence you cannot answer a neutralizing question, because the tone you have to cancel is whatever stage you stopped at.
- Neutralize with the complement, not with more of the same family. Blue cancels orange, violet cancels yellow, green cancels red. Adding gold to brassy hair makes it brassier.
- Developer volume controls lift, not deposit: 10 volume deposits, 20 lifts one to two levels, 30 lifts two to three, 40 lifts three to four. More volume is not stronger color — it is more lift and more damage.
- Permanent color cannot lighten hair that has already been tinted. "Color does not lift color" — to go lighter on previously colored hair you need a lightener or a color remover, and the exam will offer you the tempting wrong answer of a higher-volume developer.

Questions and answers, explained
All 10 questions above, with the correct answer and why it is correct. Everything here is on hair coloring and lightening.
A client's hair is described on the record card as a level 6. What does the level number describe?
Why: Level is the measure of lightness or darkness, numbered 1 for black through 10 for the lightest blonde. Warmth and coolness are described by tone, which is a separate axis — a level 6 may be ash, neutral or gold and still be a level 6. Absorption capacity is porosity, and strand diameter is texture; both are recorded during analysis but neither is what a level number means.

Why is the scalp area of a lightening application left until last?
Why: Heat from the scalp speeds the chemical reaction, so new growth lifts sooner than mid-lengths and ends. Timing it last brings the whole head to the same stage together. New growth is in fact the least porous hair on the head, not the most, and neither the weight of the product nor rinsing has anything to do with the sequence.

Before coloring damaged, porous hair several levels darker, what is applied first?
Why: A filler equalizes porosity and replaces missing primary pigment so the darker formula deposits evenly instead of grabbing in the most damaged sections. High-volume developer and powder lightener both lift, which is the opposite of the goal. Clarifying and heat would open the cuticle further and make the unevenness worse.

A client reports using a drugstore product that darkened her hair gradually over several weeks. What is the concern before any oxidative service?
Why: Gradual or progressive darkening describes a metallic salt dye. Those salts react with peroxide and ammonia, producing heat, smoke, an odor and hair that can break off or turn green. The only safe response is a metallic salt test on a cut strand before anything else. A negative patch test rules out allergy, which is a different hazard entirely.

What are the two steps of a double-process blonde service?
Why: A double process decolorizes first and deposits the finished tone second, because lightener removes pigment but cannot control the tone left behind. Patch and strand tests are preliminary checks, not the service itself. Two tint applications would not lift previously colored hair, and combining a relaxer with color on the same day is a damage risk, not a technique.

Why is a color record card kept for each client?
Why: The record card is the working history of the client's hair: formula, developer, timing, result and any reaction. It does not stand in for a release form, which serves a different purpose, and it is a confidential business record rather than something posted publicly. It also never removes the need for testing when the hair's condition has changed.

In which layer of the hair does permanent color deposit its pigment?
Why: The cortex holds the natural melanin and is where oxidative dye molecules form and stay. The cuticle is only the outer scale layer the product passes through. The medulla is the innermost core and is often absent in fine hair, and the follicle is in the skin, below the strand entirely.

A client is a natural level 6 and wants a level 8 with no added warmth. Which formulation is appropriate?
Why: Two levels of lift is exactly what 20 volume delivers, and an ash base counters the orange exposed on the way to level 8. A gold base adds the warmth the client refused. Ten volume deposits without lift so the target level is unreachable, and a level 6 target does not raise the level at all.

Tint has stained the skin along the client's forehead. What removes it?
Why: A proprietary stain remover, or a small amount of the tint worked over the mark and wiped away, lifts the stain without harming skin. High-volume developer is a chemical on unprotected skin. Abrasion irritates freshly exposed skin, and acetone is a solvent intended for nail products and has no place on a client's face.

Into how many sections is the head normally parted before a color application?
Why: The standard is four quadrants, made by parting from the center front to the nape and from ear to ear across the crown. Four sections keep the application orderly and the timing consistent. Two sections are too coarse to control application, and larger numbers belong to specific perm wraps rather than to a routine color service.
