COMPREHENSIVE TEST BANK COMPLETE QUESTIONS WITH
100% VERIFIED ANSWERS
Question 1: Compound dyes are a combination of metallic salts dyes and:
A) Synthetic dyes
B) Vegetable dyes
C) Mineral dyes
D) Oxidative dyes
Correct Answer: B) Vegetable dyes
Rationale: Compound dyes are formulated by combining metallic salts with
vegetable dyes to create a product that deposits color onto the hair shaft.
Vegetable dyes, such as henna, are natural colorants that coat the hair surface,
while metallic salts provide additional color deposition. This combination creates a
more stable color product than either component alone.
Question 2: The direction of hair growth results from:
A) The angle of the hair shaft
B) The direction of the hair follicle
C) The shape of the hair bulb
D) The size of the papilla
Correct Answer: B) The direction of the hair follicle
Rationale: The direction of hair growth is anatomically determined by the
orientation of the hair follicle within the dermis. The follicle is positioned at a
specific angle in the skin, and the hair grows in the same direction as the follicle's
alignment. This cannot be permanently changed through styling or chemical
,treatments, as it is a structural characteristic of the individual's hair growth
pattern.
Question 3: During a lightening process, which of the following will lighten the
fastest:
A) Coarse dark hair
B) Fine light hair
C) Medium brown hair
D) Coarse light hair
Correct Answer: B) Fine light hair
Rationale: Fine light hair lightens fastest during chemical processing because it
has less melanin pigment to break down and a thinner cuticle layer that allows
lightening agents to penetrate more quickly. The smaller diameter of fine hair
means the lightening agent reaches the cortex faster, while less pigment requires
less time to decolorize compared to darker or coarser hair types.
Question 4: An example of a progressive hair color product is:
A) Semi-permanent dyes
B) Demi-permanent dyes
C) Metallic tints
D) Permanent oxidative dyes
Correct Answer: C) Metallic tints
Rationale: Progressive hair colors, also known as metallic tints, gradually darken
the hair with each application through the buildup of metallic salts on the hair
shaft. These products contain metal compounds such as lead acetate, silver
nitrate, or bismuth, which oxidize and deposit color progressively over time. They
are considered difficult to remove and can cause adverse reactions with other
chemical services.
,Question 5: A flexible comb, well suited for closed tapering at the nape using the
scissors over comb technique is a:
A) Wide-tooth comb
B) Tail comb
C) Fine-tooth barber comb
D) Pick comb
Correct Answer: C) Fine-tooth barber comb
Rationale: The thin, flexible, fine-tooth barber comb is specifically designed for
the scissors-over-comb technique used in tapering. Its flexibility allows it to
conform to the contour of the head, particularly in the nape area, while the fine
teeth grip and lift the hair effectively. This comb enables precise control when
creating close, tapered finishes at the hairline.
Question 6: Which of the following statements about Demi-permanent hair color
is not true?
A) It deposits color without lifting
B) It contains low levels of peroxide
C) It lifts and deposits color
D) It lasts longer than semi-permanent color
Correct Answer: C) It lifts and deposits color
Rationale: Demi-permanent hair color deposits color onto the hair without lifting
or lightening the natural pigment. It uses a low-volume developer (usually 3-10
volume) to activate the color molecules, which penetrate the cuticle and deposit
color within the cortex. Unlike permanent color, demi-permanent does not
contain ammonia and cannot lighten hair, making statement C false.
Question 7: An important rule of safety when using disinfectants is to:
A) Use stronger concentrations for better results
B) Mix different disinfectants together
, C) Follow manufacturers directions
D) Reduce contact time to save time
Correct Answer: C) Follow manufacturers directions
Rationale: Following manufacturer directions is the most critical safety rule when
using disinfectants because these products contain chemicals that can be
hazardous if misused. Manufacturer guidelines specify proper dilution ratios,
contact times, and safety precautions based on extensive testing. Deviating from
these instructions can result in ineffective disinfection, chemical burns, toxic
fumes, or damage to surfaces and implements.
Question 8: The difference between Vellus and lanugo hair is that:
A) Vellus hair is thicker than lanugo
B) Vellus hair does not have a medulla or pigment
C) Lanugo hair is found only on adults
D) Vellus hair grows faster than lanugo
Correct Answer: B) Vellus hair does not have a medulla or pigment
Rationale: Vellus hair is the fine, soft, non-pigmented hair that covers most of the
body surface, characterized by the absence of a medullary canal and pigment.
Lanugo hair, in contrast, is the fine, unpigmented hair that covers fetuses and may
be present in some newborns, but it has a different structure and developmental
purpose. The absence of medulla and pigment distinguishes vellus hair
structurally from other hair types.
Question 9: Approximately 1% of the scalp hair is in this phase at any one time:
A) Anagen
B) Catagen
C) Telogen
D) Exogen
Correct Answer: B) Catagen
