- Q1
Which of the following is a reason cosmetologists should understand hair and scalp properties?
Identifying hair growth cycles and the differences between common and uncommon hair loss will help when recommending hair loss treatments to the client.
Identifying the elasticity of hair helps to better determine treatments to soften coarse gray hairs to match the texture of the client’s pigmented hair.
Identifying the cause of a dry or oily scalp helps to better recommend medication to the client to alleviate the condition.
Identifying the shape of hair follicles can help when recommending methods to make a client’s hair grow faster.
30s - Q2
All of the following are living portions of hair that are below the skin surface EXCEPT __________.
the dermal papilla
the hair follicle
the hair bulb
the arrector pili muscle
30s - Q3
What are the two parts of a strand of human hair?
the dermal papilla and the arrector pili
the root and the shaft
the follicle and the bulb
the cuticle and the cortex
30s - Q4
Which part of the living portion of the hair is defined as the structure in the skin or scalp that surrounds the hair root and anchors the hair in the skin?
the hair bulb
the dermal papilla
the arrector pili muscle
the hair follicle
30s - Q5
Which portion of the hair root structure supplies nutrients so that the hair can grow?
the arrector pili
the hair follicle
the hair bulb
the dermal papilla
30s - Q6
Each of the following is a layer of the hair shaft structure EXCEPT ______.
the medulla
the hair fiber
the cortex
the hair cuticle
30s - Q7
Which sentence best describes the medulla?
The medulla is a cone-shaped elevation at the base of the hair bulb.
The medulla is the hair’s outermost layer.
The medulla is the hair’s pith or core.
The medulla is the fibrous protein layer of the hair.
30s - Q8
Which layer of the hair shaft provides strength, elasticity, and color?
the hair cuticle
the hair fiber
the cortex
the medulla
30s - Q9
What are the major chemical elements that make up human hair?
proteins, water, lipids, and traces of minerals
amino acids and polypeptide chains
hydrogen bonds, side bonds, and salt bonds
carbon, oxygen, hydrogen, nitrogen, and sulfur
30s - Q10
Which of the following best describes how a disulfide bond in human hair is formed?
Sulfur atoms on neighboring cysteine amino acids within polypeptide chains in the hair join.
Oppositely charged atoms in the hair are attracted to one another to form weak physical cross-link side bonds.
Amino acids are chemically bonded to each other, end to end, to form a polypeptide chain.
Oppositely charged atoms are attracted to each other to form cross-linked side bonds between adjacent polypeptide chains.
30s - Q11
Which of the following is a situation in which a cosmetologist would allow the hair to cool before styling?
when disulfide bonds are converted to lanthionine bonds during servicing with a flat iron
when hydrogen side bonds have been broken by the heat from a curling iron
when salt side bonds are being formed by changes in pH during chemical servicing
when peptide bonds between amino acids are broken by a heat lamp during color processing
30s - Q12
If a cosmetologist holds a strand of hair with one hand while sliding the other hand’s thumb and forefinger from the end of the strand to the client’s scalp, what component of the hair is being analyzed?
density
elasticity
texture
porosity
30s - Q13
Which component of hair is defined as the thickness or diameter of an individual hair strand?
porosity
density
texture
curl pattern
30s - Q14
Which of the following can be a cause of dry hair and dry scalp?
absence of melanin
hair follicles growing out of the head at a perpendicular angle
overactive sebaceous glands
inactive sebaceous glands
30s - Q15
Which of the following best describes a procedure a cosmetologist could use to determine how quickly hair will process during chemical servicing?
Feel a strand of hair to determine the hair’s texture.
Determine the slope of the hair follicles to identify the hair growth pattern.
Examine the shape of a cross-section of a strand of hair to determine the wave pattern.
Consider how much of the scalp is visible to determine how many hairs there are on each square inch of the scalp.
